The second law of thermodynamics is correlated with the spontaneous and non-spontaneous processes. In a simple way, you can say that by the study of 2nd law you may tell more about the spontaneous and non-spontaneous process. The conceptual thinking of the Carnot cycle is that it establishes the maximum possible efficiency for any heat engine cycle operating between T 1 and T 2. The reason is that there is no friction between the piston and the walls of the cylinder.

So you cannot have isobaric and isochoric process in a carnot cycle as they will not yield maximum efficiency. A carnot cycle can only consist of Isotherms and Adiabats on a pressure vs volume graph. $\endgroup$ – BLAZE Dec 7 '16 Efficiency of a Carnot Engine. If you're we were moving when we were removing the pebbles from A to B we were moving the pebbles to keep it as a quasi-static process so that we could go back if we had to so and so that the system stayed in equilibrium the whole time if we didn't have this reservoir here the temperature would have Carnot Theorem: Two cyclic heat engines E A and E B operating between the same source and sink out of which E B is reversible (Fig. 3.15).

Such an engine cannot be realised in practice. It has maximum efficiency and it is an ideal heat engine. Sadi Carnot’s heat engine requires the following important parts. 1. A Carnot heat pump (or Carnot refrigerator) is a reverse Carnot heat engine, that absorbs heat from a cold thermal reservoir and transfers it to a warmer thermal reservoir.

Carnot process efficiency

The Carnot heat-engine cycle described is a totally reversible cycle. That is all the processes that compose it can be reversed, in which case it becomes the Carnot refrigeration cycle.

The reason is that there is no friction between the piston and the walls of the cylinder.
