Consider the process on a system shown in the figure. During the process, the work done by the system:
| 1. | continuously increases |
| 2. | continuously decreases |
| 3. | first increases then decreases |
| 4. | first decreases then increases |
An ideal gas goes from the state \(i\) to the state \(f\) as shown in figure given below. The work done by the gas during the process,
| 1. | is positive |
| 2. | is negative |
| 3. | is zero |
| 4. | cannot be obtained from this information |
| 1. | \(200\) J | 2. | zero |
| 3. | \(400\) J | 4. | \(600\) J |
