Answer:
- carnot engine is the most efficient engine,consisting of two isothermal processes and two adiabatic processes. The Carnot cycle can be thought of as the most efficient heat engine cycle allowed by physical laws. When the second law ofthermodynamics states that not all the supplied heat in a heat engine can be used to do work.
- the Carnot efficiency sets the limiting value on the fraction of the heat which can be so used.
