What Does Solubility Mean in Chemistry?
What Does Solubility Mean in Chemistry?What does solubility mean in chemistry? If you are looking for a simple, easy to understand answer to this question, it's simple - it means how solids dissolve in liquids. This is the basis of all chemists' work - from the experiments to the charts and records that they write.It's important to think about solubility in terms of viscosity. Visible solid substances are either very thin or very thick when they pass through a liquid. It can be described as their 'apparent' thickness. Think of it as if you were measuring the space between two thin pancakes, one which is already baked and the other which is just being cooled off. The first one will fall into the second - so when passing through the latter one, the first one will seem thinner.Now, let's say we have a mixture of things, each of which is water, but with different properties: each has a density which is different to the other, and each one has its own viscosity. Each time a piece of the m ixture touches a piece of the solid, it will push its density towards the thinner one, which is then pulled back out by the thicker one - until the two get to a state of equilibrium, where they are evenly dispersed.This applies to all liquids: water for example. Any of the water molecules in the mixture are required to push their own density towards the denser one, which is in turn pulled back out, leaving the more dense part in contact with the less dense. Think of it like the way cars push towards each other - the more popular the car, the faster they move. The more the car is needed to push itself forward, the slower it goes, and if you add more speed, you need more force to push it forwards.Solubilityis also a very important concept in chemical bonding. One of the main principles behind chemistry is that molecules should form stable bonds between themselves. You can't achieve this when you use different types of atoms for the different elements, so you have to use the same type of atom for all - because otherwise, when one of the atoms is excited, it causes a change in the properties of the rest of the molecule, leading to undesirable behaviour.Another example of solubility in chemistry is the fact that polar molecules (those that are in a solution) can 'float' on top of a non-polar one, allowing the solution to have a high-viscosity. This means that the amount of energy required to stop the polar molecules is much less than that required to stop the non-polar ones. So, when you don't allow the solution to form the correct type of ice crystal, the solution becomes highly viscous. Imagine the amount of power that is required to turn a car, when it has no power - the problem with this is that the friction will wear out the car! And this is exactly what happens when you apply a non-polar solution to the polar ones.Solubility is a very important concept in chemistry - and many other fields as well. So, if you want to learn more about it, you can go to your loc al library or bookshop, and you'll probably find plenty of information and references.

Mobile Minds Tutoring Suitability - The Role of Mobile Lawyer
Mobile Minds Tutoring Suitability - The Role of Mobile LawyerA few years ago I was tutoring a young lady for a month and to my surprise she told me that she had been through a lawsuit and was so upset by the experience, she couldn't see me again. I've seen a number of students in this same position, it's a serious issue that should be addressed in all classrooms, especially at first grade level. My response was that although it can be very upsetting, this was a tutor, she wasn't your typical first grader and she really didn't understand what she was talking about, so I suggested she go to a lawsuit mediation class, teach herself the legal terms and concepts and bring it up when she had time.I'm not saying that I'm the only person to have advised such a suggestion, but I did encounter it on more than one occasion. More importantly it didn't make much sense and frankly the issues that she was facing were more complicated than I could explain in a written piece.A few years ago, I worked on a case where a young lady with little experience in the law went to court and claimed that her personal injury attorney lied to her on more than one occasion during the litigation process. Her lawyer attempted to get her a continuance, but there were enough other issues to warrant the continuance, he was simply covering his behinds. What happened next is that the case dragged on for several years and then after several rounds of appeals all the way to the Supreme Court she was awarded a settlement, but not until after she had died of a heart attack.With all due respect to any first graders in elementary school, it's important to teach them everything they need to know to handle themselves in court, if for no other reason than because they are going to be sitting in the courtroom with their lives on the line and with the opportunity to teach the rest of us a lesson we might not be ready for. Since so many people have commented, I will now explain how it works.The courtroom is a v ery serious environment and one that can easily burn a hole in your pocketbook. These cases can take months and even years to resolve and a lawyer is going to work on a contingency basis, so it is possible that your case can be settled much faster than you anticipate. When a lawyer is representing a client, they get paid based on the results of the case, which means the more wins, the higher the monthly retainer fee, but it also means that if they lose the case and the client pays a retainer, that lawyer is not getting paid. There are a lot of issues that come into play when a lawyer gets compensated based on their win rate, which is why it is imperative that everyone who is working as a lawyer understands the various aspects of a case, both for themselves and for their clients.Most attorneys would be very happy to give you a referral to a personal injury lawyer, but since so many people are asking, I will give my personal advice, I've done it and I think I've helped a few individua ls find the right type of attorney for their situation. The best personal injury attorney is going to take the time to take an in depth look at the situation, look at the facts of the case and do their research.That doesn't mean they are going to fix your problem overnight, but if you take the time to work with them on your own case they can assist you in developing your own case strategy and they have the knowledge base to guide you through the legal system to see if your situation fits in with their specialty. They will discuss with you what you may not be entitled to in compensation, then evaluate whether or not they believe your case merits the attention of a specialized attorney.
