AIPMT PRELIMS 2006 Physics Carnot Cycle MCQ Question
Type: MCQ-numerical-Hard-Class 11
A Carnot engine whose sink is at 300 K has an efficiency of 40%. By how much should the temperature of source be increased so as to increase its efficiency by 50% of original efficiency?
A
275 K
B
175 K
C
375 K
D
475 K
Correct Answer
Option C
Detailed Explanation
The efficiency of a Carnot engine is given by¹⁻ (T_sink/T_source). To increase the efficiency by 50%, the new efficiency should be 60%. Solving for the new source temperature gives the required increase.
