Kinetic Theory Gas Box

Medium+70 XP

Billions of molecules crashing into the walls — that's pressure. Heat the box and watch them speed up. The math behind it is elegant: PV = nRT.

›rms speed: v_rms = √(3RT/M); most probable v_mp = √(2RT/M).
›PV = nRT; for 1 molecule, PV = NkT (k = Boltzmann constant).
