(A): The Carnot cycle is useful to understanding the performance of heat engines.
(R): The Carnot cycle provides a ways of determining the maximum possible efficiency achievable with reservoirs of given temperatures.
(R): The Carnot cycle provides a ways of determining the maximum possible efficiency achievable with reservoirs of given temperatures.
View answer and explanation
Correct option: A
Both (A) and (R) are true and (R) is the correct explanation of (A)
Option A (Both (A) and (R) are true and (R) is the correct explanation of (A)) is correct because the Carnot cycle is indeed useful for understanding heat engine performance, and the reason correctly explains why: it provides the maximum possible efficiency.
