Q137 / 160 · TS EAMCET 2024 (09 May Shift 1) · Physics

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

  • Correct answer
    A
    1
  • B
    2
  • C
    3
  • D
    4

Solution

Coefficiens of performance $\beta=\frac{1-n}{n}$ where $\mathrm{n}=$ efficiency $=\frac{1-\frac{50}{100}}{\frac{50}{10}}=\frac{0.5}{0.5}=1$

Hence, the correct answer is option: 'A'.
