Average Kinetic Energy and Temperature

State

A gas sample's average molecular kinetic energy is directly proportional to its kelvin temperature, regardless of the gas's identity.

Show

Helium and xenon at the same kelvin temperature share identical average kinetic energy, despite xenon's much greater molar mass.

Watch for

Equal average kinetic energy does not mean equal average speed — Chem 1318 shows the lighter gas moves faster on average.
