Question

Kinetic Interpretation of Temperature

Answer 1

Kinetic Interpretation of Temperature

Average kinetic energy per molecule of a gas is —

$E=\frac{1}{2} m v^{\overline{2}}=\frac{3}{2} \dot{k}_{B} T$

Average kinetic energy per molecule of a gas depends only on its absolute temperature. It is independent of pressure, volume and nature of the ideal gas.

At a given temperature, the average kinetic energy per molecule of all the gases is same.

Average kinetic energy per mole of a gas is

$E=\frac{3}{2} R T$
