Thermodynamics and Chemistry

Thermodynamics and ChemistryPhysical Chemistry Thermodynamics is the study of the structure and change of molecules in solution or gas. Molecules are made up of atoms, atoms of lighter elements and electrons, and their structures are determined by physical properties of the molecules.Chemists are now using the study of Chemistry as a tool for discovery and understanding our world around us. There are many different techniques and tools for this kind of research. One is the Theory of the Casimir force, which describes how different materials work and provides useful information on the behavior of atoms and molecules.Metals are separated into different layers according to their concentrations of metals in the molecule and how the concentration changes with the environment or energy level. Then, it is determined whether the concentration changes in a plane or a curve.As atoms move through different areas of the molecules, they attract each other. They are put together according to their energies. The concentration of atoms is changed according to the mass and the length of the atoms. The concentration depends on the interactions between the atoms.The movement of molecules can change in two ways. First, the atoms are being attracted to one another and then they separate. These are known as voids and the change of concentration in the atoms is called vacancy formation.Second, the atoms do not move around anymore but remain at the same place. The atoms have changed their position and that is called molecular motion. In this case, there is no new pattern and there is no disturbance to the environment.Models for this type of study were first developed to help researchers find out the characteristics of materials. Other models developed include particle models, which are used in physics and engineering for understanding how particles interact with the environment. In the Physics and Engineering software (PE) today, it is available for helping researchers with the study of Chemistry.

Last-minute tips for the June SAT and ACT

Last-minute tips for the June SAT and ACT As the final SAT and ACT administrations of the academic year approach, my students are asking how they should productively spend the days before the tests.  Here are a few ideas to keep in mind:Assemble everything you need for the test several days in advance.  This includes: your admission ticket, photo ID, calculator (with fresh batteries), number 2 pencils (not mechanical), an eraser, a watch, snacks and drinks.  A few notes about the watch: youre not guaranteed to have a clock in your testing room, and unfortunately the quality of proctors can be uneven.  If you bring a watch, you can time yourself on each section of the SAT or ACT and make sure that you wont be caught off guard when time is called.Sleep, stay physically active, and eat nutritious food in the few days leading up to the test.  This is good life advice in general, but its especially important when the SAT or ACT are on the horizon.  Both tests demand a great deal of endurance, and you need to be physically a nd mentally on top of your game to make it through 5 stressful hours.  Your brain will perform at its peak if your body is well-nourished and rested.  Along those lines, eat a balanced and filling breakfast on test day!Dont cram.  The SAT and ACT are not memorization tests.  While its very possible to prepare for them and improve your score, you wont significantly improve by cranking out five practice tests on Thursday and Friday.  When its a week before the test, youve already done most of the important work.  Now its about staying the course.  I recommend doing at most one section per day (for the SAT, this would be one critical reading, math, or writing section; for the ACT, either English, math, reading, or science).  Completing one section per day will help you stay fresh with the material and roll into the test on Saturday feeling confident and prepared.  Some students even benefit from doing a couple problems the morning of the test to wake up their brain but only d o that if it wont add to your stress!Keep the proper perspective.  Yes, the SAT and ACT are important tests for college admissions, but no, they wont determine the outcome of your life and your ultimate happiness.  Stay calm and confident, aim for that great score, and if you dont quite get there, remember that you can always retake in the fall!Good luck to AJ Tutorings June SAT and ACT test-takers, and enjoy your summer!

Qualities teachers appreciate in a principal

Qualities teachers appreciate in a principal We know that almost everyone sets out to be the best professional they can be - and most principals were, at one time, a teacher themselves. That being said, we understand that most principals have some ideas around what qualities make an ideal principal and school administration team. But as a world-leading teacher recruitment agency, we are well-positioned to ask teachers what qualities they think make the best principals. So what are some of the most agreed-upon qualities? Read below to see what teachers have said. Teachers like when principals model the behaviors they would like to see This is the perfect example of the expression, “show, don’t tell.” Modeling what you find to be an important quality at your school is one of the most important behaviors teachers appreciate in their principals. This could mean that you model active listening, relationship building with students, and respect. Whatever you tote as the most important qualities at your school should be modeled by both the principal and the whole administration team. It’s important for teachers to not just hear what’s valued, but see it as well. Principals demonstrate respectful listening Listening, in most professions, tops the list of important qualities. Building a strong relationship with your teachers means creating a safe environment where they feel comfortable to come forth with their feedback and concerns. One of the best tools that you can provide to teachers so that they can do their jobs well is an open ear. This needn’t require a huge time commitment either. An open door policy, or dedicated monthly meetings to allow your teachers to share their thoughts with you, can create a really healthy environment of respectful listening. You’ll also inspire your teachers to share their valuable perspectives - they’re zoomed in on the day to day classroom issues, after all. Principals are forward-thinking Being able to develop an innovative school policy and vision and then share this with all your teachers is important. This demonstrates leadership, and it means that teachers are more likely to be positively influenced by a principal’s vision. Being forward-thinking could mean any number of things for individual schools, from focusing on high expectations to using classroom data to inform school-wide decisions and promote higher performance - teachers just like to know that their principals are looking to the future. Principals consult their teachers when making school-wide decisions It’s important for teachers to feel as though they play an important part in the school and its outcomes. Teachers are, after all, the lifeblood of a school, so principals who engage their teachers at crucial decision-making opportunities can build a better relationship that benefits everyone at the school, including students. In seeking the best teachers worldwide, your school has likely acquired an intelligent and skilled arsenal of teachers. And with all this top teaching talent in-house, the need to consult outside experts is diminished. Your teachers are best positioned to help a school’s administration make the best decisions for the health of the school.

A Closer Look 8 Major World Languages Thatll Steal Your Heart

A Closer Look 8 Major World Languages Thatll Steal Your Heart One of the great thrills  of language learning is just in choosing a new system of culture, symbols and meaning to tackle.Often, the choice is not made in the head, but in the heart:Were in love with Brazilian music, and so we learn Portuguese.Were in love with a Catalan girl, and so we learn Catalan.Or were in love with cheese  and cinema, and so we learn French.But when those sorts of adventures are conquered or run aground, we might next want to pick from among the worlds 6,000 languages based on some actual foresight and pondering of the evidence.Now maybe you prefer the obscure, but if you find it  most practical to  consider one of the major world languagesâ€"which are generally defined as languages that get some use and respect beyond their own cultural/geographical groupâ€"then heres a closer look at eight of the big ones. How and Why to Pick a World  Language to LearnSince  high school, I have taken on  six languages in which I eventually became fluent, but I have also spe nt a significant amount of time (more than a year total) on completely failing to learn three more. Languages are intoxicating, alluring temptresses. It is fun to grab a textbook  and jump in.But before I had poured so much  time and effort into those three failures, I wish I had more carefully weighed their benefits, and the costs and practical issues that would eventually drag me down and cause my motivation to flag. Heres what I have found to be the top considerations to make  before taking the plunge in terms of world languages and their practicality for you.Practical considerations:Travel: How will this language enrich or enable travel experiences?Business: In my line of work, what opportunities could this language open up?Personal: Does this enrich my personal, social, family or romantic possibilities?Cultural: What music, literature, film, theater, television, etc. can I enjoy or create in this language? What activities (dance, martial arts, sports, etc.) can I take part in w ith it?Linguistic considerations:Difficulty:  How far removed is this from the languages that I know? What special challenges does this language present in terms of grammar, vocabulary, pronunciation and writing systems?Linguistic appeal:  What are the wild and interesting thrills that this languages grammar and vocabulary may open up as ways to  experience and reflect on the worlds events  and emotions?A Closer Look: 8 Major World Languages Thatll Steal Your HeartHere are the major world languages to consider, and a look at their selling points for the language-learning addict.EnglishIf youre reading this, you of course probably already speak English. But for the purposes of comparison with those to follow, consider that this is the worlds lingua franca in just about every domain.  One larger estimate puts the total number of (native, fluent and attempted) speakers at 2 billion, or roughly one-third of the worlds population. There are so many enriching thrills to be had in speaking other languages, but this is the single most practical language you can speak.That said, consider that another two-thirds of the planet dont  speak English, and that many (well, most) of those who do  speak it do so pretty badly. Youre going to have more interesting adventures in human  communication if you can master one or more of the other major world languages below.SpanishSpanish is spoken in Spain and in a large swath of the Americas, both of which are very appealing areas in which to live and travel. Instituto Cervantes puts the total number of native speakers at 470 million, and the total number of speakers worldwide at 559 million.Spanish also has an outsized cultural presence in the world thanks in particular to its contributions to music, film, literature and television. Ive met a number of people in my travels in Eastern Europe and Brazil, for instance, who have picked up Spanish simply because they enjoy dancing tango or watching telenovelas (soap operas).Many learners find this to be a relatively easy language to tackle, though any such judgement is of course subjective based in particular on your experience with languages close to it. But, if youve studied Latin, French or other Romance languages, you will of course find this approachable.It also shares a lot of words with English, particularly those which in English are descended from Latin.Pronunciation for many learners can be quite easy to approach, since there are only five base vowels to deal with and they are quite separate from each other; even if you dont hit them exactly youre still going to be understood. The writing system is also quite simple to learn, with very nearly one sound for each letter of the alphabet.FrenchThe French government tells us that there are 220 million French speakers on the planet, including those who speak it partially. It is, after English, the most taught language on the planet, and an important language for diplomacy. It is one of six working languages for the U.N., one of three procedural languages for the E.U., and the sole language for deliberations of the Court of Justice of the European Union.The language can be relatively easy to understand for English speakers because it shares a lot of cognates with English, thanks to the two languages intertwined histories. On the other hand, it has up to 17 vowels, depending on what you count, which  can make pronunciation a bit difficult, and the spelling system, while better than that of English, is not exactly straightforward.Mandarin ChineseThe Chinese government insists that Chinese is one single language, but since there are quite a number of not particularly mutually intelligible varieties under that umbrella, as a language learner youre going to have to start with just one. And in terms of practicality as a world language, your best choice is Mandarin, which has 897 million native speakers.Even Mandarin has a wide range of variation, but the standard version is a lingua franca in Ch ina, and can be used by Mandarin speakers from various dialects to communicate.For those coming from a tone-free, Latin-script-using language like English, Mandarin can certainly appear frightening, and it is indeed a challenge. It is difficult for adult learners to get used to using tones as part of communication  and memorizing the 4,000 characters known to  an average educated Chinese person is daunting.One blogger points out  the many challenges, including cultural factors that can be discouraging as well, including a Chinese propensity to laugh at any mispronounced phrase. On the other hand, Chinese has no cases, declensions or genders, and the tense system is relatively straightforward. If you have a personal desire to learn Chinese, you can rise to the challenge!ArabicAs with Chinese, Arabic is considered a single language, but from the point of view of a language learner it is a variety of not-mutually-intelligible, um, dialects, and you will have to pick one. There are 267 million total Arabic speakers in the world, and no one dialect is dominant, so youll have to pick based on which region or culture interests you the most.There is also the literary version of the language, Modern Standard Arabic. It is used in most written documents and in news broadcasts, and spoken as a second language by educated people throughout the Arab world. It is one of the six official languages of the United Nations, and it is related to Classical Arabic, which is the language of the Quran.However, from the point of view of a language learner it can be quite frustrating to have the purely spoken dialect used by people in conversations and the written form to learn as well, with little overlap between them. This means that  a decision to learn Arabic generally means learning two languages.The writing system is from right to left, and the cursive (connection of an entire word) can make it difficult to approach at first. But there is at least much more consistency between sp elling and pronunciation than one finds in English, and so reading and writing can be mastered rather quickly. The language uses  three cases, eight noun declensions, and lots of other inflections that can be challenging.RussianNative Russian speakers number 171 million  according to one count, and the language is important on the world stage, with second-language speakers located particularly in the former Soviet republics. One count puts total speakers at 260 million.This gives you a huge range of lands that you could travel over and make use of the language, and these are places where often it can be harder to find people with passable English skills.The spelling system is not as scary as it looks. The 33 letters indicate mostly regular pronunciation patterns (though stress and what it does to vowels can be hard for learners to predict). The grammar on the other hand is duly frightening; cases are complex and there are many irregularities.The same is true for verb conjugations, t hough the use of perfective and imperfective aspects  to indicate the degree to which something is finished can be rather new and fun.PortuguesePortuguese counts some 202 million native speakers in the world, and one of the main appeals is that the language provides  the best music on the planet. For me, listening to music was an unending source of motivation in  learning the language.Most learners  will decide between the European or Brazilian varieties, which are written similarly, particularly since the recent standardization, but have quite different pronunciations and vocabularies.Like Spanish and French, this is a Romance language, so if you speak either one of those languages or Latin, this will be a relatively easy project. Pronunciation of some sounds, particularly open and closed vowel sounds, can be difficult for language learners.In terms of grammar it could be considered a bit more complex than other Romance languages, as Portuguese has  more total ways to inflect verbs , although in practice many of these are not used so much, particularly in the Northeast of Brazil and among less-educated speakers.HindiHindi has  some 260 million native speakers, is the official language of a number of Indian states and is used at the national level as well by many non-native speakers. It is written in the Devanagari script, from left to right, and the pronunciation is phonetic and regular.Hindi  is an Indo-European language, and that coupled with British colonization has left some cognates between English and Hindi. Tenses are straightforward but do not of course correspond exactly to English tenses, which can make choosing the right one a bit of a challenge.Which is the best language for you? I cant tell you that, of course, but I hope that this has given you a few clues as to where you might want to head.While this post focused on world languages, you definitely may also want to consider smaller, regional languages. While they can be less useful in a practical sense, there is a real joy in being able to speak a bit of Quechua or Catalan with a native speaker, who will often be surprised and quite  grateful for your efforts.So whether you go for one of the big world languages or a lesser-known dialect, I hope you enjoy the journey!Mose Hayward blogs about language learning, dating and failure at TipsyPilgrim.com.

Chemists Guide to Nucleophilic Sites

Chemist's Guide to Nucleophilic SitesMany students taking a chemistry course want to find out more about nucleophilic sites. This information is essential for all students who take chemistry courses, whether they are taking GCSE or A-Level. The chemists will use these sites on certain molecules in various ways. An understanding of the chemistry of nucleophilic sites will give the student a much better chance of success in chemistry than a poor grasp of the subject.The knowledge of the chemistry of nucleophilic sites will enable students to learn more about molecules and how to choose those that work best for them. Students must be able to identify which of these sites would work best in their molecules and also which would need to be ignored or used carefully. With this information they will be in a position to select the sites that would work best for them.Students can obtain more information about nucleophilic sites by enrolling in the Chemistry for Science and Math (CASM) or the C hemistry for Science (CHEM) subjects. Some universities will offer courses that help students in mastering the chemistry of nucleophilic sites, as well as the molecular geometry of molecules. Other universities may offer better preparation through the preparation courses in chemistry that help students master the chemistry of nucleophilic sites.Chemists often fail to understand how molecules form and what can happen to molecules when they reach the point where they interact with other molecules. One of the main responsibilities of the chemistry tutor is to help students understand this, and to explain how to predict how a chemical reaction will go if there are a number of different reactions involved. It can sometimes be difficult for students to understand what is happening when they are not looking at the material.You can join a Texan School's Chemistry for Science and Math section and learn more about the chemistry of nucleophilic sites. They will advise youon what sites you shou ld choose for your different molecules and help you choose which site works best for you. This includes the material that will help you identify which sites will work well in your molecules and how the sites will interact with other sites, and which sites you should try to ignore, and which sites you should carefully study.You can select the site from the site selection guide given to you in the material you receive. You can also have the tutor help you select the site and will explain to you how it works and how it will affect your molecules.On the last day of the semester you can join a Texan School's Chemistry for Science and Math section. This will give you an opportunity to get more information about the chemistry of nucleophilic sites, the different molecules, and how they interact with other molecules. It will also give you the opportunity to meet some of the people involved in the section and ask questions to help you understand the material better.

What is Standard Form

What is Standard Form Standard form in Algebra is the most accepted form of a particular formula or concept. In math, standard forms can be seen in most of the topics because it gives a particular format to follow while we are performing calculations on numbers. For instance, standard form of a number 450 in general is 450, but we can also rewrite this number in another form popularly known as scientific notation as, 4.50 * 102. Hence a standard form is considered to be the format, mostly preferred in common. Example 1: Write the given equation, y = 5 2x in the standard form. Given linear equation: y = 5 2x The standard form of a linear equation is: Ax + By = C, where A, B, and C are integers and A, B are not equal to 0. Writing the given equation in standard form, we get y = 5 2x == Add 2x on both sides. This gives: y + 2x = 5 also written as 2x + y = 5. Therefore the standard (or the general) form is 2x + y = 5. Example 2: Write the given equation x(x 3) = 4 in the standard form. Given equation: x(x 3) = 4 The standard form of a quadratic equation is: ax2 + bx + c = 0, where a, b, c are integers and a is not equal to 0. Writing the given equation in standard form, we get x (x 3) = 4 == x2 3x = 4 Subtracting 4 on both sides gives: x2 3x 4 = 0 Therefore the standard (or the general) form is x2 3x 4 = 0.
