Q5NEET 1989 · AIPMTEasy

Law of Equipartition of Energy

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

Show answer and solution

Answer: (c)

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