How this entity was disambiguated
This entity first appeared as the object of triple T10417796 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

A.
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.
-
B.
Carnot cycle
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.
-
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.
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.
-
E.
Linde process
The Linde process is an industrial gas liquefaction method that enabled large-scale production of liquid air and its components, such as oxygen and nitrogen, revolutionizing refrigeration and gas separation technologies.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: Rankine cycle Description of subject: 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.
