A poly atomic gas with n degrees of freedom has a mean kinetic energy per molecule given by (if N is Avogadro's number)

Options

  1. An K T N
  2. Bn K T 2 N
  3. Cn K T 2
  4. D3 K T 2

Correct answer

C. n K T 2

Step-by-step solution

The mean kinetic energy of a polyatomic gas per molecule per degree of freedom is K .E /dof/molecule aligned & = 1 2 KT & K . E / molecule = ( 1 2 KT ) f = nKT 2 aligned
