The average kinetic energy of a molecule of the gas is (a) proportional to volume (b) dependent on the nature of the gas (c) proportional to absolute temperature (d) proportional to pressure

Answer: (c). Average KE of a molecule = 3/2kBT. It depends only on absolute temperature, not on volume, pressure or type of gas. So the answer is (c) proportional to absolute temperature.

Pressure & Kinetic Energy of a Gas

The average kinetic energy of a molecule of the gas is

Show answer and solution

Answer: (c)

Average KE of a molecule $= \frac{3}{2}k_BT$ .
It depends only on absolute temperature, not on volume, pressure or type of gas.
So the answer is (c) proportional to absolute temperature.
