Thermodynamic Process & Cycle

Thermodynamic Process:

 

When a system changes its state from one equilibrium state to another equilibrium state, then the path of successive states through which the system has passed is known as thermodynamic process.

Thermodynamic Cycle or Cyclic Process:

When a process or processes are performed on a system in such a way that the final state is identical with the initial state, it is then known as thermodynamic cycle or cyclic process.
