At the same temperature, how does the average kinetic energy of H₂ molecules compare with that of O₂ molecules?

Correct answer A. It is the same

Explanation

Average kinetic energy depends only on absolute temperature, not on molar mass. Lighter H₂ molecules move faster, but their average kinetic energy equals that of O₂.
