Choose an option

Show full solutionCorrect option: A
Correct answer
A12kBT

Step-by-step explanation

Energy associated with each degree of freedom per molecule =12kBT.

Hence, the average value of energy along one degree of freedom for an ideal gas in thermal equilibrium at a temperature T =12kBT.
