Degrees of Freedom & Internal Energy

An insulated container contains a diatomic gas of molar mass ' m '. The container is moving with velocity ' $V$ ', if it is stopped suddenly, the change in temperature is ( $R =$ gas constant)

Show answer and solution

Answer: (b)

Per mole: $\frac{1}{2}mV^2 = C_v\Delta T$ (no heat lost, insulated).
Diatomic: $C_v = \frac{5}{2}R$ .
$\Delta T = \frac{mV^2}{5R}$
So the answer is (b) $\frac{mV^2}{5R}$ .
