MCQ
Consider the process on a system shown in figure. During the process, the work done by the system:
- ✓Continuously increases.
- BContinuously decreases.
- CFirst increases then decreases.
- DFirst decreases then increases.
✓
Answer
Correct option: A.
Continuously increases.
Explanation:
Work done by a system, $\text{W}=\int\text{PdV}$
Here,
P = Pressure on the system
dV = change in volume
Since dV is positive, i.e. the volume is continuously increasing, work done by the system also continuously increases.
