The efficiency of a reversible heat engine working between two temperatures is \(50 \%\). The coefficient of performance of a refrigerator working between the same two temperatures but in reverse direction is
- A 1
- B 2
- C 3
- D 4
Answer & Solution
Correct Answer
(A) 1
Step-by-step Solution
Detailed explanation
Coefficiens of performance \(\beta=\frac{1-n}{n}\) where \(\mathrm{n}=\) efficiency \(=\frac{1-\frac{50}{100}}{\frac{50}{10}}=\frac{0.5}{0.5}=1\)
