Understanding the Carnot Principle
The Carnot efficiency defines the theoretical upper limit of efficiency for any heat engine operating between two thermal reservoirs. It is named after the French scientist Sadi Carnot, who derived this principle in 1824.
Absolute Temperature
Efficiency depends solely on the temperatures of the hot and cold reservoirs in Kelvin. A Carnot engine can only achieve 100% efficiency if the cold reservoir is at absolute zero (0 K), which is physically impossible.
Ideal Cycle
The Carnot cycle is a theoretical model of an ideal engine. Real-world engines are less efficient due to friction, heat loss, and other irreversible processes.
