A polyatomic gas with n degrees of freedom has a mean energy

Home » Thermal Physics » Kinetic Theory » Question

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

1. nkT
  N
2. nkT
  2N
3. nkT
  2
4. 3kT
  2

Correct Option: C

According to law of equipartition of energy, the energy per degree of freedom is

	1	kT
	2

For a polyatomic gas with n degrees of freedom, the mean energy per molecule

=	1	nkT
	2
