Ideal Gas Law Chemistry

Ideal Gas Law ChemistryAn ideal gas law can be defined as a model of chemical equilibrium. This model has many aspects to it, but the key aspect is that each chemical reaction generates heat (in the form of kinetic energy) to balance the activity of each molecule.The idea behind this law is that gases are very rarely exactly the same in concentration and in the molecules they contain. For example, a gas that contains carbon monoxide can vary from one molecule to the next depending on the kind of reaction that produces the carbon monoxide. Therefore, if we could take a mass of any kind of molecule and then analyze the chemical reactions that produced the gas, we would have a pretty good idea of what the equilibrium mixture is and how much variation is normal.We all know that a very large quantity of gas will produce a much higher temperature than a smaller quantity of the same gas. In other words, there is no reason why a gas's temperature should ever decrease. If the gas were to decr ease in temperature, the equilibrium would not be present. That is why we see water boils at relatively high temperatures compared to gasoline or other fuels.An ideal gas law basically states that the heat of combustion is inversely proportional to the energy released by the combustion process. This law is based on the idea that the bigger the volume of the combustion zone, the greater the heat is produced and the higher the temperature that the gaseous mixture will reach in the long run.On a microscopic level, chemical reactions always take place in a highly ordered fashion. When you break these chemical systems down, it is possible to observe what is happening at the molecular level, and the ideal gas law is very effective for predicting how the system will react.To understand the best way to use the ideal gas law, you must first understand that any chemical reaction that causes an atom to lose a small amount of energy is referred to as 'decay'. It is important to remember that ev ery reaction has a corresponding molecular mechanism. A similar type of diagram is used to explain this kind of fact.Just like the gases we were discussing earlier, the ideal gas law also comes into play when studying the atomic structure of a molecule. When this happens, one may ask what kind of reaction is happening. In order to answer this question, a set of chemical equations is used to calculate the amount of heat needed to cause the atoms to lose their electrons.Another important point to note is that the ideal gas law is still applicable when dealing with organic molecules. In fact, the efficiency of the combustion is significantly higher when using organic substances. We could say that the chemistry of gases and organic chemistry are closely linked.

According to a study by the American Foreign Service Institute, or FSI, the Romance language is one of the easiest living languages in the world to learn.As with all language programs around the world, the levels of French language have been set out in a framework created by the European Union known as the CEFRL for European languages. These levels aren’t just for English speakers, but for everyone trying to gauge their knowledge of French. There are six levels ranging from the basic, A1, to the level of complete fluency, C2.The B2 level, an intermediate step that means you are able to listen to French audio and express yourself easily in both written and oral terms, is the one normally required for entry into public un iversities for a language study or maths and sciences. Oral expression is particularly important in French universities, meaning you will have to work on perfecting your accent.The FSI study has grouped some popular living languages into different groups corresponding to the amount of time it will take to reach an advanced level of knowledge.Group 1, 24 to 30 weeks of learning: French, Danish, Dutch, Italian, Norwegian, Portuguese, Romanian, Spanish, SwedishGroup 2, 36 weeks of courses: German, Indonesian, MalaysianGroup 3, 44 weeks: Armenian, Czech, Farsi, Finnish, Greek, Hebrew, Hindi, RussianGroup 4, 88 weeks: Arabic, Chinese, Japanese, KoreanAccording to this guide, you might be able to get by in French by trying out some coffee break French podcasts or by listening to some modern French radio channels â€" something that would be near impossible to do with a language like Mandarin Chinese.However, looking at the study, if you’re interested in learning more than just basic gram mar rules or French verb and syntax rules, you’ll need to put in more than 480 hours. Using a coffee break or podcast method should, theoretically, be enough to get you to a level A1 or even A2.If you’d like to reach a more advanced level, however, you might want to consider taking a French lesson either online or with a language institute. According to the study, the FSI recommends spending 600 to 750 hours over 24 to 30 weeks in order to reach a B2 or C1 level in French.This is pretty significant, considering that as a foreigner, you will be able to reach high degrees of autonomy in a language in as little as 6 months!In conclusion, to reach an intermediate level, you will need to study 10 hours a day for 48 days â€" which is the some actually many choose.However, many of us don’t actually have that sort of time to set aside for language â€" unless you’re Canadian French and probably spend most of your day practicing anyways. Here are some tips on what to expect on your jo urney towards becoming fluent.Discover the best French classes London here.One way to get free lessons in French is to simply move to a Francophone cityWhat Are the Components in Learning FrenchWhether you’re studying through a language exchange, French classes or simply by memorizing your phrasebook â€" it’s clear that the amount of time you spend learning is one of the most important factors in language acquisition.There are, however, several other components you’ll have to take into account when studying both French or any of the other Romance languages. Not mentioned below, but can be found with this guide, is a price comparison between the different types of courses you're likely to encounter.What is the Right Methodology?The methodology under which you learn French will vary significantly from the type of learning you’re engaging in â€" be it through Duolingo or through live, conversational French practice with French people.For most people, taking French courses at a university or through private lessons with a native French speaker will result in a much quicker understanding of the language than through self-teaching methods.From walking you through the basics of the French alphabet to understanding the complex rules of French verbs, following a French course has many benefits â€" the most important one being regularity. A French language school or tutor won’t just guide you to your desired level of French, be it beginner French or bilingualism, but it will also help you appreciate French culture and history.The Framework of Studies in FrenchAs with studying any of the many unofficial and official languages around the world, practising French daily is an imperative step towards mastering the linguistics of the language.In order to do this, it will be important to define your goals from the beginning. Whether your goal be in the form of a French internship to living and working in the country, chances are you’ll probably have to take a stand ard French exam.The acronyms for these tests are the DELF, DALF and the TCF, all of which do not have the same levels. In order to prepare for these, the ideal framework would be to study under an intensive program.If you’re looking for free French language resources, there are plenty of French online options: Campus France, Le Point du FLE, Bonjour de France, and the Alliance Franciase. Fortunately, you don’t have to be a master at French to be able to access these sites.MemorizationLearning French, as with all languages, will involve some memorization skills. The recommended way to learn French vocabulary is to divvy up the words you want to learn by what they deal with. For example, for vocabulary words concerning the hospitality sector, you will have to learn specific vocab like the words for hotel, restaurant, bar service, building, tourism, etc.Learning vocabulary doesn’t just deal with memorization, but also the frequency with which you learn these words â€" a lesson al ong the lines of the phrase “use it or lose it.”A study by Harry P. Bahrick concluded that without practicing, people who had studied a language forgot about 60% of their vocabulary in the 3 years after they stopped actively learning it.French people are some of the best language teachers!Living in France to Become a FrancophoneWhile a French course might teach you about French pronunciation or French conversation, there is no language course that can teach you â€" whether it be online French or through a private French teacher â€" better than your own ears.In the mid-1960s, linguist and neurologist Eric Lenneberg developed an important theory on language which stated that acquiring an native accent in a language after puberty is impossible if someone has only been surrounded exclusively in their maternal language their whole lives.More generally, this is known as synaptic pruning â€" a process in which your brain gets rid of informational ties it has not used until then.While t his might seem like a dreary picture for those looking to acquire perfect French as an adult, a French immersion program might be in your best interest. While learning a new language is always stressful and language courses can sometimes conflict with even the most flexible of schedules - becoming a native speaker through intensive French lessons is highly effective.While acquiring your second language can be accomplished through beginners and intermediate level courses, where your language skills will be refined by learning about French language and culture - you can also consider moving to France. Whether it be through an student, internship or another professional opportunity - you will learn new words and phrases daily just as a product of living there.If you'd like to learn French while living somewhere that you can still speak your native language, there are many options to start learning French in the UK. From tutors on our website to UK universities - your journey to master French doesn't have to start tomorrow.

Charcoal Drawing

Charcoal Drawing An Introduction To Drawing with Charcoal ChaptersCreating Highlights Using CharcoalSketching With CharcoalChoosing And Sticking With The Best BrandsThe Benefits Of A Simple Medium For BeginnersCharcoal is a dry art technique often made from natural or organic resources like wood. Some vine charcoal is literally made by burning willow. Just like graphite pencils, charcoal can be used on a smooth surface. However, for best results, charcoal should be used on textured paper.Charcoal is an art medium that is made from natural sources like wood. Photo on VisualHuntThe Freedom Charcoal Offers To NovicesLearning to draw with charcoal is very fun as the key to this style of art is to make big, bold, sweeping movements across your surface, and it doesn’t matter how messy it gets! The various types of charcoal are great for creating highlights and shadows to give the illusion of basic forms and light.The technique comes in either sticks, which you can break down as you so wish, or in pencil form. As you can imagine, the raw sticks of charcoal offer you more flexibility as you can either draw straight onto your surface, scratch the pigment off of them to blend on the paper, or rub them on their side to create large blocks of colour.Keeping On Top Of The MessWhile charcoal drawings are intended to look rough and ready, one thing to remember is that you too will get a bit messy - it has that in common with pastel and chalk drawing. If you don’t want to end up with dirty prints all over your clothes, house or, worse, your piece of art, then make sure you keep some cleaning wipes close by and regularly wash your hands.It can be so disappointing to create a wonderful piece of art that you are really happy with and then ruin it with silly mistakes like leaving grubby fingerprints on it! A blessing is that charcoal doesn't require much, if any clearing up afterwards like paints and clay. You just put your charcoal pencils or sticks away ready for the next drawing session - no having to wash up endless paintbrushes in the sink!Charcoal is a low-maintenance medium but it might leave your hands a bit messy! Photo credit: Scott Woods-Fehr on VisualhuntImportant Questions To Ask Yourself Before You StartBefore you begin to sketch with charcoal, you will need to think about a few things like what you want to draw, what equipment you will need and what surface you will use.There are three types of charcoal: pencil, vine and stick.Pencil charcoal offers a finer point and is cleaner to apply, plus pencils come in a range of styles from hard to soft, just like normal pencils. Vine charcoal, meanwhile, is a soft form of the medium that will create very solid black lines, getting inside the grooves of your textured paper.The last, however, offers the deepest black but it can also come in other colours too. You can find hard or soft charcoal sticks and use them to create the darkest shadows of your piece.You can create highlights and definition in charcoal drawings by applying pressure and using a rubber to take colour away. Photo credit: Neil Tackaberry on VisualHunt.comSo when we said that you could create highlights with charcoal, that was a small white lie! You will need a secondary tool like a rubber (or another medium like white chalk) to add this definition in to your shading.Choosing And Sticking With The Best BrandsYou can research the best brands of mediums online or ask someone who has experience using them, but the best way to decide which is right for you is to actually try them yourself. Get a good feel for what they are like to hold, their smell, how smooth the application is and so on. Even the tiniest elements can make a big difference in how happy you are drawing with them.If you feel comfortable using a particular brand, then you will be more confident and this will be reflected in your drawing.Canson Mi-Teintes, Canson Ingres, Strathmore 500 Series and Fabriano Tiziano are popular choices of charcoal, while good pencil forms are often from firms that also make co loured pencils or crayons  Conte and Faber-Castell Pitt, Grumbacher, Winsor Newton, Derwent and Coates.The Benefits Of A Simple Medium For BeginnersOne thing to remember is that, as its name suggests, charcoal is a simple and often monotone material. Yet, it can still be used to produce some fantastic pieces of work. Impressive drawings have been created by artists all over the world displaying landscapes and portraits in both traditional and contemporary styles.If you want to see just how far the technique can be manipulated, search 3D charcoal drawings on your Internet search bar to find clever images that quite literally jump out at you.You wouldn’t have believed it possible to create such life-like drawings with just your hand and a piece of charcoal!Another big draw is that charcoal is cheap to buy and is a low-maintenance medium. All you need is some paper, your charcoal pencils or sticks, a chamois and a rubber and you're ready to get started!Some artists choose to lock th eir final image in place with a specialist a fixative spray.  You can find this product in most art shops.Find drawing classes with a tutor on Superprof -Drawing courses LondonDrawing courses EdinburghOnline drawing lessons

How to make changes that stick - Introvert Whisperer

Introvert Whisperer / How to make changes that stick - Introvert Whisperer How to make changes that stick Change is really at the heart of any goal if you think about it and making a change is tough for many reasons.   First, you have to be motivated enough to tackle an issue that you’ll take action on.   But, if starting isn’t a challenge, keeping the momentum and focus can be the place where all good goals meet their death. How do you avoid derailing your goal?   Glad you asked! :- You have to plan for failure, diversion or loss of focus.   You can call it whatever you want but you have to realize that in all goals or changes, the initial enthusiasm will evaporate so you have to plan ahead before you even get started.

The power of another person to help you stay accountable to help you focus on the end result is the very best structure you can have. Put some skin in the game â€" I have found both as a business owner and personally that when a person has to shell out money, they are more invested in their outcome.

Guide to Language Learning Goals

Guide to Language Learning Goals Why You Need Language-Learning Goals ChaptersWhat to Avoid When Setting Language Learning GoalsHow to Successfully Approach Language LearningLanguage Is ComplexWhat Is a Goal?How to Break Apart Your Language Learning GoalsHow to Set S.M.A.R.T. GoalsKeep Your Language-Learning Goals RealisticOften, when people start learning a new language, they jump right into it. They’ll download an app and start swiping and typing away to fluency. Or so they think. But jumping into language-learning with this mindset can not only lead to wasted time, but it can also prevent you from actually learning a new language.If you’re going to learn a new language, then you need goals. Without them, you’ll get lost in the forest, looking for the trees. To help you make the most of this process, you need a guide to creating language learning goals that will help you rapidly reach fluency.Specific: In detail, describe what you want to achieve. List out why, how, and under what conditions you wish to achieve them. The more details you can pr ovide, the better.Measurable: In what objective way can you measure your progress to gauge success?Attainable: Is your goal realistic? Analyze yourself as a learner and make sure that you’re not creating unrealistic expectations for yourself.Relevant: How does this goal relate to your overall goal?Timely: Set a specific and reasonable deadline to achieve your goal.Setting goals for your learning can help you keep on track.What’s An Example of a S.M.A.R.T. Goal?A general goal would be saying something like, “I want to speak German.” A more specific goal would be saying something like, “I want to speak German at a B2 level.”But a S.M.A.R.T. goal goes much deeper and more specific:“I want to speak German at a B2 level in 1 year so that I can travel to Germany for 2 weeks practising my language skills on a language holiday. I’m going to do this by sitting down every day for 45 mins and working on my language skills using my favourite languaging program, YouTube, and Netf lix.Plus, I’m going to reach out to friends that I know speak the language and ask them to help me practice. I’ll make sure to spend time on each domain as well, but because my goal is to speak the language, my primary focus will be on listening comprehension and speaking. I also plan on taking the B1 Test at 6 months and then the B2 test before I go on my trip.”Keep Your Language-Learning Goals RealisticThis point bears repeating and revisiting. While some language-learners will promise unrealistic progress with various programs, the key to success is being realistic language learning. Know who you are, how you learn, and why you want to reach fluency in a foreign language. Then take the time to layout your specific, detailed goals.With a clear plan and focus, you’ll achieve results much faster. With achievable goals, you’ll also have far more moments where you can take a step back and reflect on your success, giving you the motivation you need to keep going until you fin ally reach fluency.

Teacher Tips to Get the New Year off to a Great Start

Teacher Tips to Get the New Year off to a Great Start Holiday break is behind you, yet your students still seem to be in vacation mode. What can you do to get things back on track quickly? Here are a few ideas for how to re-energize students for the winter semester: Catch up. Talk with your students about what they enjoyed about their breaks. Make the transition a little smoother by easing into the work and giving students a chance to restore that camaraderie with their classmates. Set class goals. Surely you have an agenda for this semester, but rather than tell students what it is, talk through your objectives for student outcomes and get their buy-in. Invite student input where you can. Go over expectations. January is a good time to refresh students memories on class expectations and processes that you went over at the start of the school year. Share your expectations and consequences for not meeting them and trust your students to behave accordingly. Have students write their own goals. Some students might have already thought about their New Years resolutions why not dedicate some class time to that process, too? The first week back to school, ask students to think about what they want to accomplish this semester, academically and otherwise, the steps theyll need to take to get there, and how you as their teacher can support them. Tidy up. Get your classroom in order, and have your students get their desks, binders, and backpacks in order, too. Yes, you could spend your free time doing this, but getting your students involved gets them more invested. Survey students. What did they like about the fall semester? What projects or lessons were particularly engaging? Talk about things youd like to do differently throughout the winter and spring and ask for their ideas. Lastly, be enthusiastic yourself! Nothing is more inspiring than your own attitude, so if youre eager and forward-looking, theres a greater chance that your students will be, too.
