View answer

A carnot engine operating between two temperatures 727°C and 27°C is supplied heat energy at the rate of 500 joule/cycle. 60% of the work output is used to derive a refrigerator, which rejects heat to the surrounding at 27°C. If the refrigerator removes 1050 Joule of heat per cycle from the low temperature reservoir, determine the temperature (in Kelvin) of reservoir. Correct answer is '250'. Can you explain this answer?
