A Carnot engine operating between two temperatures 727°c and 27°c is supplied heat energy at the rate of 500 Joule / cycle. Sixty percent of the work output is used to drive a refrigerator, which reject heat to the surrounding at 27°c. If the refrigerator removes 1050 Joule of heat per cycle from the low temperature reservoir. Then
  • a)
    Work input = 210 J
  • b)
    Work input = 270 J
  • c)
    Temperature of reservoir = 250 k
  • d)
    Temperature of reservoir = 230 k
Correct answer is option 'A,C'. Can you explain this answer?
