$\frac{1}{2} P V$
$3 P V$
$\frac{3}{2} P V$
$\frac{5}{2} P V$

A

\frac{1}{2} P V

B

\frac{5}{2} P V

C

Solution

Verified by Toppr

The no of translational degrees of freedom for mono atomic or diatomic gas is same and is 3.
Hence, translational KE will be same at same temp for both gases.
Mono atmic gas has only translational degree of freedom.
Hence, translational kinetic energy for diatomic gas is $\frac{3}{2} P V$
