Q. No.An ideal gas undergoes four different processes from the same initial state as shown in the figure below. Those processes are adiabatic, isothermal, isobaric, and isochoric. The curve which represents the adiabatic process among \(1,\) \(2,\) \(3\) and \(4\) is:
| 1. | \(4\) | 2. | \(1\) |
| 3. | \(2\) | 4. | \(3\) |

Match the thermodynamic processes taking place in a system with the correct conditions. In the table, \(\Delta Q\) is the heat supplied, \(\Delta W\) is the work done and \(\Delta U\) is the change in internal energy of the system.
| Process | Condition | ||
| (I) | Adiabatic | (A) | \(\Delta W=0\) |
| (II) | Isothermal | (B) | \(\Delta Q=0\) |
| (III) | Isochoric | (C) | \(\Delta U\neq0, \Delta W\neq0,\Delta Q\neq0\) |
| (IV) | Isobaric | (D) | \(\Delta U=0\) |
Codes:
| 1. | (I) – (B), (II) – (A), (III) – (D), (IV) – (C) |
| 2. | (I) – (A), (II) – (A), (III) – (B), (IV) – (C) |
| 3. | (I) – (A), (II) – (B), (III) – (D), (IV) – (D) |
| 4. | (I) – (B), (II) – (D), (III) – (A), (IV) – (C) |
