Reversible and Irreversible Process

* REVERSIBLE PROCESS:- When a process is reversed in direction, follows same path as that of forward process path without leaving any effect on the system and surrounding is known as Reversibsle Process.

* IRREVERSIBLE PROCESS:- A process which is not reversible is known as Irreversible Process.

NOTE:- Reversible processes are most efficient processes but they are ideal process(Not real), because friction is not zero anywhere.
