Example $18\mathrm{.}2$: An important feature of the Carnot cycle is that

A$.$ its efficiency can be $100\%.$

B$.$ its efficiency depends only on the absolute temperature of the hot reservoir used.

C$.$ its efficiency is determined by the temperatures of the hot and cold reservoirs between which it works and by the properties of the working substance used, and on nothing else.

D$.$ it is an example of an irreversible process that can be analyzed exactly without approximations.

E$.$ no engine can be more efficient than a Carnot engine operating between the same two temperatures.
