Question

What is not true for a cyclic process?

Answer 1

Cyclic process:

1. A cyclic process is one in which the initial and final states are the same. It is a series of processes that returns the system to its initial state.
2. The initial and final internal energies of a system are equal when it goes through a cyclic process.
3. As a result, in any cyclic process, the internal energy change is zero.
4. $\mathrm{W}=0$ does not apply to cyclic processes.
5. As a result, in a cyclic transformation, the work done by the system equals the heat absorbed by the system. A refrigerator or air conditioner is an example of such a system.

Therefore, $\mathrm{W}=0$ is not true for the cyclic process.
