4. Carnot Engine: It consists of a cylinder with ideally heat insulating frictionless piston. Further whose walls are ideally heat insulating and base is ideally heat conducting. An ideal gas is enclosed in the cylinder. For the operations of carnot engine it is also supposed that source and sink are of infinite capacities.

5. Entropy: Entropy of a system is the measure of the molecular disorder
Entropy: Entropy of a system is the measure of the molecular disorder. It is also defined as the measure of the unavailability of useful energy in the system.
