At constant temperature, the product of an ideal gas's pressure and volume is always constant.

k=PV

For an ideal gas at constant pressure, the volume is proportional to the absolute temperature.

V=kT

The pressure exerted on a container's sides by an ideal gas is proportional to the absolute temperature of the gas.

P=kT

The volume occupied by an ideal gas is proportional to the number of moles of gas present in the container.

V=kn

Shows the relationship between the pressure, volume and temperature for a fixed mass of gas.

PV=kT

Shows the relationship between the pressure, volume, number of moles, and temperature of a gas.

PV=nRT

The rate at which gas molecules diffuse is inversely proportional to the square root of its density.

(rate 1)/(rate 2)=(M2/M1)^(1/2)

The pressure of a mixture of gases is the sum of the partial pressures of the individual components.

Ptotal=P1+P2+...Pn

At a constant temperature, the amount of a given gas dissolved in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with
