Oxygen molecules are 16 times more massive than hydrogen molecules.At a given temperature,the average molecular kinetic energy of oxygen molecules,compared to that of hydrogen molecules,
A)is greater.
B)is less.
C)is the same.
D)cannot be determined without knowing the pressure and volume.

Question

Quizplus · Accepted Answer

The average molecular kinetic energy of gases depend on their temperature only, and not their mass. Therefore, at a given temperature, the average kinetic energy of both oxygen and hydrogen molecules will be the same.
