Question
Explain cyclic process with the help of neat and labelled p-V diagram.
✓
Answer
(1) A thermodynamic process that returns a system to its initial state is a cyclic process.
(2) In this process, the initial and the final state is the same.
(3) For a cyclic process, the total change in the internal energy of a system is zero. $(\Delta U =0)$
(4) According to the first law of thermodynamics, we have, for a cyclic process, Q = W
(5) Working of all heat engines is a cyclic process.
