Q.32. Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Statement I: Change in internal energy of a system containing n mole of ideal gas can be written as $\Delta U = nC_v (T_f - T_i) = \frac{nR}{\gamma-1} (T_f - T_i)$, where $\frac{C_P}{C_V} = \gamma = \frac{T_f}{T_i}$ = initial temperature, T = final temperature. Statement II: Relation between degree of freedom f and $\gamma (= C_P/C_V)$ is $\gamma = 1 + \frac{2}{f}$. Choose the correct answer from the options given below
