The efficiency of the Carnot engine is and the temperature of the sink is . If the temperature of the source is kept constant and its efficiency raised to , then the required temperature of the sink will be
View answer and explanation
Correct option: C
Option C (400 K) is correct because it is calculated by first finding the source temperature using the initial efficiency and sink temperature, and then finding the new sink temperature for the increased efficiency.
