Question

4. Is there any enthalpy change in a cyclic
process? If yes, give example.​

Answer 1

Answer:

Enthalpy is a state function; which means change in enthalpy depends only on final and initial state. So ∆H for a cyclic process is zero.

In a cyclic process, the system starts and returns to the same thermodynamic state. ... A cyclic process is the underlying principle for an engine. If the cycle goes counterclockwise, work is done on the system every cycle. An example of such a system is a refrigerator or air conditioner
