Answer 2

Example of the cyclic process:
The Carnot cycle is the best example of the cyclic process which is explained below:

The Carnot cycle:
The cycle was first discovered by a French engineer Sadi Carnot in 1824 which works on reversible cycle and is known as Carnot cycle.
Carnot employed a reversible cycle to demonstrate the maximum convertibility of heat into work. any fluid can be used to operate the Carnot cycle which is performed in an engine cylinder the head of which is suppose alternatively to be perfect conductor or a perfect insulator of the heat.

Following are assumptions which are made by Carnot engine during its working:

(i) The piston moving in a cylinder does not develop any friction during motion.

(ii) The walls of the piston and cylinder are considered to be perfect insulators of heat.

(iii) The transfer of the heat does not affect the temperature of source or sink.

(iv) Working fluid is taken as an ideal gas.

(v) Compression and expansion are reversible.

The system consists of one mole of an ideal gas which is subjected to a series of four successive operations, commonly termed as four strokes, which are discussed below and consider the figure below
