an ideal cycle of reversible engine operations in which a substance at one temperature is compressed adiabatically to a second temperature, expanded isothermally at the second temperature, expanded adiabatically from the second temperature to the first temperature, and compressed isothermally at the first temperature.
an idealized reversible heat-engine cycle giving maximum efficiency and consisting of an isothermal expansion, an adiabatic expansion, an isothermal compression, and an adiabatic compression back to the initial state
an engine using a Carnot cycle of operations.
a device operating on the Carnot cycle in which the first temperature is higher than the second.
- Carnot principle
noun the principle that no heat engine can be more efficient than one operating on a Carnot cycle of reversible changes
- Carnot’s theorem
the principle that no engine operating between two given temperatures can be more efficient than a Carnot engine operating between the same temperatures.
