Kinetic Energy
When the temperature in a gas increases, the gas molecules will become
faster and therefore more energetic.
We may say that the temperature represent "the average kinetic energy
of the particles of a substance".
Knowing that two ideal gases with the same amount of molecules occupies
the same volume and that the total amount of kinetic energy
in these two volumes must be the equal, less massive gases will diffuse
more rapidly than more massive gases at equal pressure and temperature.
This according to the kinetic energy equation:
Ek=1/2mv2
