    Given below are two statement: Statement - I : When μ\mu amount of an ideal gas undergoes adiabatic change from state (P1, V1, T1)\left( P_{1},{\text{ }V}_{1},{\text{ }T}_{1} \right) to state (P2, V2, T2)\left( P_{2},{\text{ }V}_{2},{\text{ }T}_{2} \right), the work done is  W=μR(T2−T1)1−γ\ W =\frac{\mu R\left( T_{2}-T_{1} \right)}{1 - \gamma}, where γ=CPCV\gamma =\frac{C_{P}}{C_{V}} and R=R = universal gas constant, Statement - II: In the above case. when work is done on the gas. the temperature of the gas would rise.
