Answer» Solution :In the year 1824 a young FRENCH ENGINEER Sadi CARNOT proved that a certain reversible engine operated in cycle between hot and cold reservoir can have maximum efficiency. This engine is called Carnot engine. A reversible heat engine operating in a cycle between two temperatures in a particular way is called a Carnot Engine. The carnot engine has four parts which are given below. (i) Source: It is the source of heat maintained at constant HIGH temperature `T_(H)`. Any amount of heat can be extracted from it, without changing its temperature. (ii) Sink: It is a cold body maintained at a constant low temperature `T_(L)`. It can absorb any amount of heat. (iii) Insulating stand: It is made of perfectly non - conducting material. Heat is not conducted through this stand. (iv) Working substance: It is an ideal gas enclosed in a cylinder with perfectly non-conducting walls and perfectly conducting BOTTOM. A non - conducting and frictionless piston is fitted in it.
