ideal gas constant

8.31 (L ** KPA)/(K**mol)

Boyles Law

For a given mass of gas at constant temperature, the volume of gas varies inversly with pressure

Dalton's Law of partial pressures

At constant volume and temperature,the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures of the component gases

ideal gas law

p ** v = n ** R * T

Combined gas law

(p1 ** v1)/(t1) = (p2 ** v2)/(t2)

Charles law

the volume of a fixed mass of gass is directly proportional to the Kelvin temperature if the volume is kept constant

diffusion

a gas tends to move to an area of lower concentration until the concentration is uniform throughout

partial pressure

the contribution each gas in a mixtur makes to the total pressure

effusion

a gas escapes through a tiny hole in its container

Grahams law

the rate of effusion of a gas is directly proportional to the square root of the gas's molar mass.

Compressability

a measure of how much volume of matter decreases under pressure
