So my book say's
I mean, wouldn't molecules with bigger mass have more inertia and therefore would travel slower with the same amount of energy (which is related to temperature)?
"A molecule's average translational kinetic energy depends only on the temperature, not on the molecule's mass. If two gases have the same temperature, their molecules have the same average translational kinetic energy."
My question is, why?I mean, wouldn't molecules with bigger mass have more inertia and therefore would travel slower with the same amount of energy (which is related to temperature)?
