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 less.
B) is greater.
C) is the same.
D) cannot be determined without knowing the pressure and volume.

Question

Quizplus · Accepted Answer

The average molecular kinetic energy of a gas at a given temperature is the same for all gases, regardless of the molecular mass, according to the kinetic theory of gases. This is because the kinetic energy is directly proportional to the temperature (in Kelvin).
