Carnot states that a hot body is required that generates heat and a cold body to which the caloric is … WebCarnot Cycle. The most efficient heat engine cycle is the Carnot cycle, 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 of thermodynamics states that not all the supplied heat in a heat engine can be used ...
WebSadi Carnot, a French military engineer, was determined to answer a central question of his ear: “whether the motive power of heat is unbounded,” and “whether the possible improvements in steam engines have an assignable limit, a limit which the nature of the things will not allow to be passed by any means whatever” [1]. WebNo - in that case, the two engines would cancel each other out and there would be no net work and no net heat transfer. The two engines would do nothing. It is the equivalent of x …
