NEET 2015 Physics Carnot Cycle MCQ Question
Type: MCQ-numerical-Medium-Class 11
A Carnot engine having an efficiency of 1/10 as heat engine, is used as a refrigerator. If the work done on the system is 10 J, the amount of energy absorbed from the reservoir at lower temperature is:
A
1 J
B
90 J
C
99 J
D
100 J
Correct Answer
Option B
Detailed Explanation
The efficiency of a Carnot engine is given by η =¹⁻ T_c/T_h. As a refrigerator, the energy absorbed is given by Q_c = W/η, leading to 99 J.
