Question

What is a cyclic process?

Answer 1

This is a thermodynamic process in which the thermodynamic system returns to its initial state after undergoing a series of changes. Since the system comes back to the initial state, the change in the internal energy is zero. In cyclic process, heat can flow in to system and heat flow out of the system. From the first law of thermodynamics, the net heat transferred to the system is equal to work done by the gas.

Q_net = Q_in – Q_out = W (for a Cyclic Process)

Answer 2

The process in which the initial and final state is the same is known as a cyclic process. It is a sequence of processes that leave the system in the same state in which it started.

 When a system undergoes a cyclic process, its initial and final internal energies are       equal. Hence, the internal energy change in any cyclic process is zero.
