Can work be done by a system without changing its volume?

Step-by-Step Verified Solution

**Answer:** Yes, work can be done by a system without changing its volume. **Step-by-Step Explanation:** In a **cyclic process**, the system returns to its initial state, so the net change in volume is zero. However, the net work done over the complete cycle is **not zero**�it equals the area enclosed by the cycle on the PP-VV diagram. So work can be done even though ΔV=0\Delta V = 0 for the entire cycle [citation:8][citation:10].
