Today I will be about how temperature pressure affect a gas. There are two laws that apply to this topic. They are Charles Law and Boyle's Law. First off you need to know why the volume of a gas changes. The volume of gas because of the increase and decrease in the speed in which the molecules bounce around. Okay, now that you know that I can tell you about Charles Law.

Charles Law states that if the pressure remains the same, the amount of space a gas takes up will increase if the temperature rises and will decrease if the temperature is lowered.
The formula for Charles Law is...

Example of this is if you take a half- empty balloon and put it in a freezer. As the temperature is decreased because its in a freezer the amount of space the gas takes up will decrease. If its put next to a heater the amount of space a gas takes up will increase because the temperature is being increased.

Now to Boyle's Law.
Boyle’s Law states that if temperature stays the same, the amount of space a gas takes up will increase if the pressure decreases. The amount of gas will take up less space if the pressure is increased.
The formula for Boyle's Law is....
Example of this is if you squeeze a balloon together. As you squeeze your hands together the pressure will increase and the amount of space the gas takes up will decrease. As you take your hands off the balloon and the pressure decreases the amount of space the gas takes up will increase.
