A carnot engine operates between temperature T and 400 K (T>400 K). If efficiency of engine is 25%, the temperature T is:
View answer and explanation
Correct option: C
533.3 K
Option C (533.3 K) is correct because the efficiency of a Carnot engine is given by , where is the cold reservoir temperature and is the hot reservoir temperature. Solving for with the given efficiency yields approximately 533.3 K.
