The molecules of different samples of an ideal gas have the same average kinetic energies, at the same
A) pressure.
B) temperature.
C) volume.
D) density.

Question

Quizplus · Accepted Answer

The average kinetic energy of a gas molecule is directly proportional to the temperature of the gas. Therefore, if different samples of an ideal gas have the same average kinetic energies, they must have the same temperature. The pressure, volume, and density of the gas do not affect the average kinetic energy of the gas molecules, as long as the temperature is held constant.
