What is a cyclic process? Write a note on it.

(N/A) cyclic process is a thermodynamic process in which a system undergoes a series of changes and eventually returns to its initial state.
In a cyclic process,the initial and final states of the system are identical. Since internal energy is a state function,the change in internal energy for a complete cycle is zero.
$\therefore \Delta U = 0$
According to the first law of thermodynamics:
$\Delta Q = \Delta U + \Delta W$
Since $\Delta U = 0$,we have:
$\Delta Q = \Delta W$
This means that for a cyclic process,the net heat absorbed by the system is equal to the net work done by the system. If the system absorbs net heat,work is done by the system,and if the system rejects net heat,work is done on the system.
