An effusion law that states lighter molecules will effuse faster than heavier ones. Dalton's law of partial pressure Effusion Charles's law Graham's law of effusion

Graham's law of effusion

A gas law that associates the product of the pressure and volume with the number of moles, temperature, and a universal proportionality constant. Ideal gas law Dalton's law of partial pressure Kinetic molecular theory Effusion
