Refer to figure given below. Let \(ΔU_1\) and \(ΔU_2\) be the change in internal energy in processes \(A\) and \(B\) respectively, \(ΔQ\) be the net heat given to the system in process \(A + B\) and \(ΔW\) be the net work done by the system in the process \( A + B.\)
For the above figure:
| (a) | \(\Delta U_1+\Delta U_2=0\) |
| (b) | \(\Delta U_1-\Delta U_2=0\) |
| (c) | \(\Delta Q-\Delta W=0\) |
| (d) | \(\Delta Q+\Delta W=0\) |
Choose the correct option from the given ones:
| 1. | (a), (b) | 2. | (b), (c) |
| 3. | (c), (d) | 4. | (a), (c) |
