MCQ
For a cyclic process, the change in internal energy of the system is _______________ .
- Aalways + ve
- Balways - ve
- Cnone of these
- ✓zero
✓
Answer
Correct option: D.
zero
(d) zero
Explanation: For a cyclic process, the initial state is the same as that of the final state. As internal energy is a state function, its value at the initial point is the same as that at the final point and enthalpy change is zero.
