Gassy

So we started gas laws today, and they are not that bad. Mostly its math, and we have a lot of rules, but it doesn't matter, as I am sort of good a math. Anyway the first thins to know is the basic principles of a gas,being that:

they expand spontaneously to fill their container,
they are highly compressible,
they form homogeneous mixtures,
and they have molecules relatively far apart from one another and exert little influence on each other.

For more information refer to THIS video.

One of the key parts of a gas, and Gas Laws, is pressure, which we will define as the frequency of the gas particles contacting the side of its container. The more common units of measuring pressure of a gas are as follows:

However we are not likely to use Bar. It is also good to know that 1 atm. is equivalent to air pressure at sea level.

Now that that's out of the way,it would be good for you to learn Boyle's Law. It is the simplest and easy to learn. So Boyle's Law states that if you have a gas, and keep the temperature of that gas, as well as the amount of that gas constant, then the pressure of that gas multiplied by the volume of that gas will be equal to the changed pressure of that gas multiplied by the changed volume of that gas. If that didn't make sense, go HERE to learn more. The equation looks a little like this:

And the relationship, in a graph, looks like this.

In short, the volume of a substance is in a inverse relationship with the pressure if, and only if, the temperature and amount are held constant.

Thanks for watching.
