Question
Consider a process shown in the figure. During this process the work done by the system
- Continuously increases
- Continuously decreases
- First increases, then decreases
- First decreases, then increases
The correct answer is: Continuously increases
As the volume is continuously increasing and the work of expansion is always positive, so the work done by the system continuously increases
