QNEET-2017-Ph-1006: NEET 2017 Physics - Class 11 NEET-2017-Ph-1006 Solution: A carnot engine having an efficiency of \( {1}{10}\) as heat…
A carnot engine having an efficiency of 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 90 J 99 J 100 J 1 J
Multiple Choice Options
- A 90 J
- B 99 J
- C 100 J
- D 1 J
Step-by-Step Verified Solution
Given, efficiency of engine, _ = 1 10
work done on system W = 10J
Coefficient of performance of refrigerator
_ = Q 2 W = 1 _ _ _ = 1 _ 1 10 1 10 = 9 10 1 10 = 9
Energy absorbed from reservoir
Q 2 = _ w
Q 2 = 9 _ 10 = 90 J
