MCQ
For a cyclic process, the change in internal energy of the system is _______________ .
  • A
    always + ve
  • B
    always - ve
  • C
    none 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.
