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 |
