The average kinetic energy of the molecules in a gas sample depends only on the temperature, T. But given the same kinetic energies, a lighter molecule will move faster than a heavier molecule. rms speed = Squareroot 3RT/ where R=6,314 J/(mol middot K) and is molar mass in kilograms per mole. What is the rms speed O_2 molecules at 333 K? What is the rms speed of He atoms at 333 K?
