Describe working of Heat engine
Heat engine is a device by which a system is made to undergo a cyclic process that results in conversion of heat to work.
* It having of a working substance-the system. Eg. a mixture of fuel vapour and air in a gasoline.
* The working substance goes by a cycle having of several processes. In some of these processes, it absorbs a total amount of heat Q1 from an external reservoir at some high temperature T1
* In some other processes of the cycle, the working substance releases a total amount of heat Q2 to an external reservoir at some lower temperature T2
