Law of Equipartition of Energy

A polyatomic gas with nn degrees of freedom has a mean energy per molecule given by

Show answer and solution

Answer: (c)

  1. Law of equipartition: each degree of freedom has average energy 12kT\dfrac{1}{2}kT per molecule.
  2. With nn degrees of freedom: E=n×12kTE = n \times \dfrac{1}{2}kT
  3. So the answer is (c) nkT2\dfrac{nkT}{2}.
