Even though the average speed of a carbon monoxide molecule is greater than that of a sulfur dioxide molecule at the same temperature, the average kinetic energy of the molecules is the same.

Question

Quizplus · Accepted Answer

The average kinetic energy of gas molecules depends only on the temperature, not on the mass of the molecules. At the same temperature, all gas molecules have the same average kinetic energy, regardless of their mass.
