Solvents - What Do They Do?

Solvents - What Do They Do?Physical Chemistry is sometimes referred to as Physical Chemistry, and Chemical Kinetics is the Science of reactions. Understanding this might help you understand the physical actions of solvents and gases. When considering how your solvents react in your material, it's vital that you understand Chemical Kinetics and its relationship to Physical Chemistry.The chemistry of solvents is highly complex, but the result is actually quite predictable. When considering your material and how it reacts, it is important to understand what solvents do to your material. First, it's important to understand what solvents do to your material. Next, when we understand the relationship between solvents and solids, we can better understand Physical Chemistry and the chemistry behind solvents.It's important to understand how solvents interact with solids and liquids in order to develop a good understanding of how solvents work within a Physical Chemistry lab. If you're not sur e what solvents due to solids, then you may want to consider a Molecular Approach Solutions Manual PDF. It might be worth your time to consider a PDF before you do any research, because it will go over what solvents due to solids, what solvents do to liquids, and how solvents and liquids interact.Solvent saturation may occur at any place on a solid surface. Solvent saturation is something that is dependent on the molecular weight of the solvent, which is determined by the amount of water that has already been dissolved within the solute. Solvent saturation occurs where the molecules of the solute are the same as those of the solvent. At other times, the solute may have the right number of molecules for solvent saturation, but the molecule that would form an H-bond would have one extra atom which would make the bond break instead of the H-bond forming. At other times, the bond formation may occur due to the presence of a chiral element, where the component that has the right number o f atoms for solvent saturation has the wrong number of chiral atoms.Physically, solvents work on solids by combining the surface area of the solid with a solid which will further increase the surface area. In doing so, the solute can spread out, allowing more surface area to be exposed. A solute can spread out in a variety of ways. If the solute is moving slowly, it will create a very large droplet of the solute on the surface, allowing it to allow more surface area to be exposed.Surfactants which come into contact with solids are known as solutes. These solvents react with the surface of the solute to make the surface of the solute more permeable. In other words, the solute will not only penetrate but it will also allow more surface area to be exposed. These solvents are usually a mixture of water and an alcohol, as an example.Solvents which are not liquids will often be referred to as gasses. The gasses generally have a lower density than solvents and will typically come in a gel form. Gases react to a solid material by giving up a little bit of their volume. The gasses that react to the solute's surface have a greater density than the gasses that react to the solid's volume. This means that the gasses are attracted to the solid by the surface tension and are driven to the surface.When gasses react to a solid, it's important to understand what solvents are. Solvents act as modifiers and help a solvent to be transported on the surface of a solid. Examples of solvents include: ether, phosphoric acid, caustic soda, and many others. Gases and solvents can react on a solid surface, and when they do, they will cause a reaction that leads to either an increase or decrease in the solute's concentration on the surface.

4 Tips to Get a Study Abroad Experience at Home

4 Tips to Get a Study Abroad Experience at Home Tips From an Irvine College Consultant: 4 Tips to Get a Study Abroad Experience at Home Many students would like to study abroad but simply dont have the opportunity for one reason or another. Students who would like to become global citizens can mimic the study abroad experience to some degree without actually spending a semester in another country. Here are four tips from a private Irvine college consultant to get a study abroad experience at home. 1. Join an international club or society Students who are new to college can join the International Students Club or other multicultural society on campus. One of the greatest things about visiting another country is meeting the local people. Although it is good to learn about new people in their home environment, students who join an international club will get to meet new friends and classmates from all over the world. These friendships can be just as valuable as if they were made in another country (READ: 4 Things Study Abroad Students Dont Expect to Find in America). 2. Visit an urban area near campus Although many students do not have the opportunity to travel abroad, they will likely have the opportunity to travel to a major city within the US. In some ways, and when done right, this experience can mimic a small portion of the study abroad experience. For instance, cities such as San Francisco, Chicago, and New York all have vibrant and diverse cultural communities. Students who are able to travel to these types of cities on vacation can sample the foods, cultures, and living experiences of people throughout the world. This is one of the reasons why living in the melting pot of the US is so advantageous. 3. Study art or art history Students who take a class in art or art history will learn about artistic and cultural expression from all over the globe. Students can generally choose from Western art or Eastern art and will have the opportunity to view the history of other cultures through the eyes of their artists and musicians. Art history students are also encouraged to visit a local art museum with an international collection to get some insight into other cultures (CLICK: Best Art Museums in Orange County). 4. Choose a university that boasts an international student community Many major public universities will make a huge effort to have a diverse and international student population living and studying on campus. US-based students who would like to have a multicultural experience, but who are not able to study in another country, are advised to do research about the percentage of international students on campus at the colleges they are intending to apply. Students at such universities are bound to run into a diverse group of people and engage in a multicultural education (READ: How Should I Start My College Entrance Essays?). In short Although the study abroad experience isnt for everybody, (it’s a big step and is also quite expensive) there are several ways that students can stay at home in the US but still begin to become global citizens. Learning about different cultures, backgrounds, and languages is a great first step to becoming a well-rounded and educated adult. It is also a wonderful way to learn to communicate effectively and enjoy the company of different types of people once in the work place. The US is such a diverse melting pot where students can enjoy an excellent international experience right here at home.

Why Your Lack Of Sleep Might Also Be The Cause Of Your Weight Gain

Why Your Lack Of Sleep Might Also Be The Cause Of Your Weight Gain image via Pixabay A recent experiment that focused on the question of over-eating revealed the neurological impulses (triggered by lack of sleep) that compel people to snack more during the day. The reason for this phenomenon? After a poor night’s sleep, junk food becomes far more appealing due to the marijuana-like chemicals already present in the brain, whether you’re a smoker or not. This chemical, scientifically known as endocannabinoid 2-arachidonoylglycerol (2-AG), resembles the same chemicals found in cannabis, but is naturally created by the brain. The chemical affects pain, pleasure and, no surprise here, appetite. As reported in the journal, “Sleep,” when test subjects were deprived of sleep, their 2-AG levels stayed higher, longer, and they consequently snacked on unhealthy foods. To put it simply: people find junk food harder to resist at this stage. The study was fairly small, but intensive, as there were 14 participants (all in their 20’s) who agreed to stay at the University of Chicago’s sleep center for four days. These subjects stayed in light and sound controlled rooms and had meals that were measured and prepared by the researchers so that everything that was eaten could be properly recorded. These subjects underwent strict sleep schedules, some allowed to sleep eight and a half hours and others only allowed to sleep four and a half. Researchers also took blood samples and chose what and when the volunteers could eat. For four nights, no one could eat until 3 p.m., at which point they were allowed to eat their fill of their favorite foods. Another meal was served at 7:30 p.m. According to the research, everyone overate at the 3 p.m. meal (an average of 2,000 calories taken in during this sitting). However, at the 7:30 meal time, those that got more sleep only ate an average of 600 more calories, while those awakened every day at 5:30 a.m. (which cut their sleep time in half) ate another 1,000 calories at that time. Typically, blood levels of 2-AG are low overnight and rise slowly and peak in the early afternoon. In the sleep-deprived test subjects, these 2-AG levels rose higher and remained higher throughout the evening. According to Erin Hanlon, a research associate in endocrinology at the University of Chicago that helped to lead the study, “We know sleep restriction inhibits cognitive performance. It inhibits impulsivity. You are more driven to overeat.” This relationship between poor sleep and overeating is of course far more complicated than it may seem after this study, as it probably lies in several other biological compounds as well, but it’s nevertheless there, and it’s something that needs to be taken more seriously. According to NBC, “Two thirds of Americans are overweight or obese. And the CDC says more than a third of Americans are not getting enough sleep. Obesity and a lack of sleep both raise the odds of heart disease and other health problems and a lack of sleep is clearly linked with obesity.” So what’s the next step? See where the 2-AG is getting overproduced. “I’d love to be able to figure out where the endocannabinoids are coming from. We know that it is made in the brain,” but Hanlon also said it may be made in the stomach or fat cells. According to Hanlon, “We are hoping to bring awareness to the fact that individuals need to think of adequate sleep and a good sleep routine as important aspects of maintaining good health. People need to stop invoking the old adage of I’ll sleep when I am dead.” However, this idea may be much harder to implement than meets the eye. Studies continuously show that artificial lights in computer and television screens are capable of causing insomnia and so can the overuse of social media and as college students, it’s safe to say those three components compose the entirety (or at least a majority) of our day. Also, the CDC says that there isn’t any real, proven sleep aid. So those 9 million Americans that claim to take sleeping pills may not be seeing any benefits. So get some sleep tonight your health may just depend on it.

The Advantages of Teaching Group Tutorials

ChaptersIndividual Private Tutorials or Group Private Tutorials?How Should Group Tutorials Be Conducted?Group Tutorials: Why Learn in a Group?What Are the Disadvantages of Group Lessons?“Tell me and I forget. Teach me and I remember. Involve me and I learn.” - Xun KuangPrivate tutorials are recommended for pupils who are struggling in a variety of subjects: languages, music, science, humanities, etc.The tutoring market in the UK is estimated at £2bn per year and has been growing in recent years with over 40% of pupils in London having received tutoring in some form.This can make teaching private tutorials very appealing to aspiring tutors. Home tutoring is becoming increasingly popular for test prep, helping students with their homework or an assignment, and providing academic support for a semester or throughout the whole academic year.Not convinced?In our final  article in our series on teaching group tutorials, we’re looking at the advantages of teaching multiple students i n private tutorials.

(Source: StockSnap)Private tutorials are an opportunity for a student to go back over something they didn’t understand in class in a relaxed environment where they won’t be scared of giving a wrong answer or being judged by the peers.Sociologists have noted that it’s normally the upper classes who can afford private tutorials for struggling students. Additionally, th e children of the upper classes are statistically less likely to fail at school than those from the working classes, which you might think isn’t really fair.Private tutorials are a significant expense for some families and can put a bigger strain on those with lower household incomes.  That said, academic support can still help close the gap between the classes in terms of education as students can get help with subjects they might be having trouble with at school.Private tutorials and academic support provide students with a number of benefits: some children prefer to work in a group tutorial as they work better than they do in class at school.Let’s have a look at the two options available to parents and students: individual private tutorials and group private tutorials.A group class will have the costs divvied up between all the students. Group classes provide learning in a friendly environment where students are encouraged to share learning with each other.The classes normall y include a group no larger than 10 (though this will vary depending on age and subject) and students are supposed to learn from both the tutor and one another.Some subjects are better for group lessons than others, especially subjects like languages, music, sport and fitness, and maths.  On the other hand, group sewing classes or group exam prep classes aren’t really as good.It completely depends on what the objectives of the tutorials are...How Should Group Tutorials Be Conducted?You’ll read that you can get group classes in any subject you like for students in primary school, secondary school, and beyond.Group tutorials can be really sociable. (Source: Free-Photos)There are different types of group classes such as intensive tutorials, catchup tutorials during the school holidays, and preparation classes for the upcoming school year. The main benefit is that the tutors and students can develop a better rapport with one another than they can in individual private tutorials.They can also learn at a quicker rate than in class as their tutor can spend more time with them, adapt to their learning style, and help them achieve the grades that they really deserve.Another difference with group tutorial is that they tend to take place at a dedicated classroom rather than a student’s home.  Flexibility is essential for private tutors.  The more tutees the private tutor has, the more flexible they’ll need to be, both in class and when they plan their lessons.Private tutorials can take place in the evenings and during the school holidays.  This is especially true for the tutors on Superprof, who often offer tutorials to individual students and to groups of students in dedicated classrooms either at their home or elsewhere.Can you really teach all subjects to groups at any level?Even for the best tutors, there are some subjects that can’t be taught in groups.  A guitar lesson tends to be better with individuals whereas language lessons and subjects which require discussion are much better in groups.Group Tutorials: Why Learn in a Group?Learning in a group is a great way for some students to catch up with what they’re struggling with at school.Learning with others can be far more enjoyable than learning on your own. (Source: coyot)There are plenty of other advantages to private group tutorials.Firstly, the law of supply and demand can help: The more students in a class, the less per person that each student has to pay.Generally, a private tutorial costs between £15 and £30 per hour.  In a group class, a tutor could charge £30 per student for a two-hour tutorial.The student can learn twice as much for less.The tutor can also earn more. For example, £150 for two hours of classes with 5 students rather than £60 for two hours with a single student.Group classes can be more effective than individual classes: students learn together and share.  They also create social bonds with other students.  This can help students rebuild their confide nce after a bad year at school or when their confidence is knocked when they start struggling in a certain subject.Let’s consider a Spanish lesson, for example: having the group discuss a Spanish text and speaking to one another than encourage students to learn. Another advantage is that most teachers in state schools have to plan a class for dozens of students at once.Even with the best intentions and a myriad of teaching approaches, they can’t always teach in exactly the way they’d like.  Instead, they may have to digress, focus on a particular point, and make sure every student is on the same page before advancing.Let’s go back to our example of a Spanish class. Rather than doing a list of irregular verbs, a private tutor could make Spanish conjugation into a game.How?By incorporating the verb conjugations into simple phrases in a conversation with the students.  Thus, they’ll improve their speaking and listening skills without realising they’re even studying.Private tutorials are an opportunity for students to catch up, consolidate their studies, and feel equal to their peers by being helped academically in the heart of a group experiencing the same difficulties as them.What Are the Disadvantages of Group Lessons?It’s not all good, though. Everything has its pros and cons.Of course, group tutorials aren't always fun and games. (Source: WokinghamLibraries)A private group tutor summed it up perfectly:“One of the disadvantage of group classes is that certain students are more advanced than others, which can demotivate those who don’t have the resources to catch up with them.”The problem is that not every student advances at the same rate, just like in primary school or secondary school.There’s also geography. If students need to travel across town by car, bus, tram, or metro to get to the classroom, they can get demotivated on the way.  In some cases, parents just don’t have the time to take their kids to another class.Not bothered by the disadvantages?You can find a tutor on Superprof easily by searching your subject and where you live. This will provide you with a list of tutors providing academic tutoring in your area. If you select “via webcam” when you search, you can find an online tutor.If you're worried about the cost or getting the wrong tutor, don't forget that most of the tutors on Superprof offer free tutoring for the first hour so you can see if you or our child get along with them and whether the tuition they're offering is for you.Interesting in providing your own private tutoring services?If you create your profile on Superprof, you can offer instruction in plenty of subjects including physics, mathematics (calculus, algebra, geometry, trigonometry, etc.), chemistry, biology, English, French, Spanish, etc.You just have to create your profile and state what you teach and where you teach it. You have the option of offering individual tutorials or group tutorials.As we mentioned earlier, you can also offer online tutoring via webacm. However, unless you and all your students have a really good internet connection, this is much better for one on one tutoring than for group tutoring jobs.With all that said, nothing's impossible and since you're your own boss, it's up to you to decide to solution that works for you and what you want to teach!
