The Gas Laws

emperature :
The temperature of a gas is a measure of the amount of kinetic energy the gas particles possess, and therefore reflects their velocity distribution. If we followed the velocity of any single particle within a gas, we would see it changing rapidly due to collisions with other particles and with the walls of the container. However, since energy is conserved, these collisions only lead to exchange of energy between the particles, and the total number of particles with a given velocity remains constant i.e. at a given temperature, the velocity distribution of the gas particles is conserved.

Pressure Volume Temperature Relationships
Boyle s Law: The Pressure-Volume Law
Boyle s law or the pressure-volume law states that the volume of a given amount of gas held at constant temperature varies inversely with the applied pressure when the temperature and mass are constant.N
Another way to describing it is saying that their products are constant.
PV = C
When pressure goes up, volume goes down. When volume goes up, pressure goes down. From the equation above, this can be derived:
P1V1 = P2V2 = P3V3 etc.
This equation states that the product of the initial volume and pressure is equal to the product of the volume and pressure after a change in one of them under constant temperature. For example, if the initial volume was 500 mL at a pressure of 760 torr, when the volume is compressed to 450
mL, what is the pressure? Plug in the values:
P1V1 = P2V2
(760 torr)(500 mL
