What is cyclic process ? Write note on it.

Explanation

A process in which a system undergoes series of changes and which returns the system back to its initial state is known as cyclic process.
In cyclic process the initial and final states of system is same hence internal energy for this process is zero.
`therefore DeltaU=0`
From first law of thermodynamics
`DeltaQ=DeltaU+DeltaW`
`therefore DeltaQ=DeltaW`
If a system absorb heat then work is done by the system and when a system reject heat then work is done on the system.
