Question

what is coefficient of cornot heat engine ​

Answer 1

Answer:

Thus, it implies that the total entropy change of the furnace and sink is zero, for the process to be reversible and the efficiency of the engine to be maximum. This derivation is carried out in the next section. The coefficient of performance (COP) of the heat engine is the reciprocal of its efficiency.

The efficiency of cornot's heat engine is independent of nature of working substance.

The efficiency depends on Temperature pf source and sink (T1 - T2)

Then heat will not be converted into mechanical work
