The temperature of a gas is measure of (a) the average kinetic energy of gas molecules. (b) the average potential energy of gas molecules. (c) the average distance between the molecules of a gas (d) the size of the molecules of a gas

Answer: (a). Average KE per molecule = 3/2kT, so T ∝ average KE. Ideal gas molecules have no potential energy, and T does not depend on spacing or size. So the answer is (a).

The temperature of a gas is measure of

Show answer and solution

Answer: (a)

Average KE per molecule $= \frac{3}{2}kT$ , so $T \propto$ average KE.
Ideal gas molecules have no potential energy, and $T$ does not depend on spacing or size.
So the answer is (a).
