Which of the following statements is true about the Carnot refrigeration cycle?
It operates between two temperature reservoirs and has the highest possible efficiency.
It operates between two temperature reservoirs and has the lowest possible efficiency.
It operates between multiple temperature reservoirs and has the highest possible efficiency.
It operates between multiple temperature reservoirs and has the lowest possible efficiency.
Explanation: The Carnot refrigeration cycle is an idealised cycle that operates between two temperature reservoirs. It is based on the Carnot principle, which states that no refrigeration cycle operating between two temperature reservoirs can have a higher efficiency than a Carnot cycle. Therefore, the Carnot refrigeration cycle has the highest possible efficiency.
