Carnot devised an ideal engine which is based on a reversible cycle of four operations in succession : isothermal expansion, adiabatic expansion, isothermal compression and adiabatic compression. are same. The system must always be in thermal and chemical equilibrium with the surroundings. Two systems are said to be in thermal equilibrium with each other if they have the same temperature. This means that heat energy cannot be created or destroyed. On differentiation, we get slope of adiabatic curve, It is clear from equation (1) and (2) that the slope of adiabatic curve is more steeper than isothermal curve as shown by fig by γ time (γ = C.
