In a cyclic process, a system undergoes a series of changes and returns to its initial state. During this process, the total change in internal energy (ΔU) of the system is zero because the initial and final states are the same.

According to the first law of thermodynamics:
ΔU=q+w

Since ( ΔU = 0 ) for a cyclic process, the equation becomes:
0 = q + w

Rearranging the equation, we get:
q = -w
