Q. No.The figure shows the \((P\text-V)\) diagram of an ideal gas undergoing a change of state from \(A\) to \(B\). Four different paths \(\mathrm{I, II, III}\) and \(\mathrm{IV}\), as shown in the figure, may lead to the same change of state.
| (a) | The change in internal energy is the same in cases \(\mathrm{IV}\) and \(\mathrm{III}\) but not in cases \(\mathrm{I}\) and \(\mathrm{II}\). |
| (b) | The change in internal energy is the same in all four cases. |
| (c) | Work done is maximum in case \(\mathrm{I}\). |
| (d) | Work done is minimum in case \(\mathrm{II}\). |
