Solution

The correct option is B Statement -1 is True, Statement-2 is True; Statement -2 is NOT a correct explanation for Statement-1.
Average energy of a molecule of an ideal gas at temperature T= $\frac{1}{2} m v^{2} = \frac{3}{2} k T$
Therefore the total energy of the gas = $\frac{3}{2} N k T$
where N is the total number of molecules.
Since Nk=nR,
Average energy = $\frac{3}{2} n R T = \frac{3}{2} P V$
