Physics - Heat & Thermo Question with Solution | TestHub

Two moles of monoatomic gas is expanded from $\left(P_0,V_0\right)$ to $\left(P_0,2V_0\right)$ under isobaric condition. Let $\Delta Q_1$ be the heat given to the gas, $\Delta W_1$ the work done by the gas and $\Delta U_1$ the change in internal energy. Now the monoatomic gas is replaced by a diatomic gas, other conditions remaining the same. The corresponding values in this case are $\Delta Q_2,\Delta W_2,\Delta U_2$ respectively, then
