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) | The work done is maximum in case \(\mathrm{I}.\) |
| (d) | The work done is minimum in case \(\mathrm{II}.\) |
Which of the following options contains only correct statements?
| 1. | (b), (c) and (d) only | 2. | (a) and (d) only |
| 3. | (b) and (c) only | 4. | (a), (c) and (d) only |

An ideal gas undergoes a cyclic process \(ABCDA\) as shown in given \(P\text-V\) diagram given below. The amount of work done by the gas is:
1. \(6 P_0 V_0\)
2. \(-2 P_0 V_0 \)
3. \(+2 P_0 V_0 \)
4. \(+4 P_0 V_0\)
1. \(6 P_0 V_0\)
2. \(-2 P_0 V_0 \)
3. \(+2 P_0 V_0 \)
4. \(+4 P_0 V_0\)
