Target entity: Carnot heat engine Context triple: [Kelvin–Planck statement of the second law of thermodynamics, relatedTo, Carnot heat engine]
-
A.
Carnot cycle
chosen
The Carnot cycle is an idealized thermodynamic cycle that defines the maximum possible efficiency any heat engine can achieve when operating between two temperature reservoirs.
-
B.
Carnot efficiency
Carnot efficiency is the theoretical maximum efficiency that any heat engine can achieve when operating between two temperatures, serving as a fundamental limit in thermodynamics.
-
C.
Carnot
Carnot is a French surname most famously associated with mathematician and physicist Sadi Carnot, a founder of thermodynamics, and several prominent political and military figures in France.
-
D.
Rankine cycle
The Rankine cycle is a thermodynamic power cycle that converts heat into mechanical work using phase changes of a working fluid, forming the basis of most steam power plants.
-
E.
Brayton cycle
The Brayton cycle is a thermodynamic cycle commonly used in gas turbine engines, where air is compressed, mixed with fuel and combusted, and then expanded through a turbine to produce work.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
