A Carnot heat engine has an efficiency of 10 % . If the same engine is worked backward to obtain a refrigerator, then the coefficient of performance of the refrigerator is

Options

  1. A8
  2. B9
  3. C5
  4. D6

Correct answer

B. 9

Step-by-step solution

For heat engine, _E=10 % If same engine works as a refrigerator, then ( COP )_R= 1- = 1-0.1 0.1 =9
