PhysicsNEET 2020Degrees of freedom, law of equipartition, specific heats

Kinetic Theory

The average thermal energy for a mono-atomic gas is: ( $k_{B}$ is the Boltzmann constant and $T$ is the absolute temperature)

A. $\frac{1}{2} k_{B} T$
B. $\frac{3}{2} k_{B} T$ ✓
C. $\frac{5}{2} k_{B} T$
D. $\frac{7}{2} k_{B} T$

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
