Solution

The correct option is B 1.4
Potential energy, $U = \frac{f}{2} n R T$ and $C_{V} = \frac{f}{2} R$

Where,

$f$ is degree of freedom.

For diatomic gas, $f = 5$

$C_{V} = \frac{5}{2} R$

$C_{P} = C_{V} + R = \frac{5}{2} R + R = \frac{7}{2} R$

Specific heat ratio, $γ = \frac{C_{p}}{C_{v}} = \frac{7}{5} = 1.4$

Hence, specific heat ratio is $1.4$
