Question
Heat is being supplied to a system but the system does not perform any external work. Is it possible? If yes, how?
✓
Answer
Yes, it is possible. If total quantity of heat $\Delta\text{Q}$ supplied to a system is retained by it as its increase in internal energy $\Delta\text{U}$ i.e., $\Delta\text{Q}-\Delta\text{U,}$ then the external work done by the system AW is zero. Isochoric process is an example of this type of process.
