Q. No.The following figure shows two processes \(A\) and \(B\) for a gas. If \(\Delta Q_A\) and \( \Delta Q_B\) are the amount of heat absorbed by the system in two cases, and \(\Delta U_A\) and \(\Delta U_B\) are changes in internal energies, respectively, then:
| 1. | \( \Delta Q_A>\Delta Q_B,~ \Delta U_A>\Delta U_B \) |
| 2. | \( \Delta Q_A<\Delta Q_B,~ \Delta U_A<\Delta U_B \) |
| 3. | \( \Delta Q_A>\Delta Q_B, ~\Delta U_A=\Delta U_B \) |
| 4. | \( \Delta Q_A=\Delta Q_B, ~\Delta U_A=\Delta U_B \) |
