What will be the average value of energy along one degree of freedom for an ideal gas in thermal equilibrium at a temperature T ? ( k B is Boltzmann constant)

Question

TestHub · Accepted Answer

Energy associated with each degree of freedom per molecule $= \frac{1}{2} k_{B} T .$

Hence, the average value of energy along one degree of freedom for an ideal gas in thermal equilibrium at a temperature $T =$ $\frac{1}{2} k_{B} T .$
