where T is the Kelvin temperature, M is the molar mass in kg/mol, and
R= 8.314 J/(mol - K) is the gas constant. Effusion is the escape of gas
molecules through a tiny hole into a vacuum. The rate of effusion of a gas is
directly related to the rms speed of the gas molecules, so it's inversely
proportional to the square root of its mass. The rms speed is related to
kinetic energy, rather than average speed, and is the speed of a molecule
possessing a kinetic energy identical to the average kinetic energy of the
sample. Given its relationship to the mass of the molecule, you can
conclude that the lighter the molecules of the gas, the more rapidly it
effuses. Mathematically, this can be expressed as
