Question

A Carnot engine operating between a reservoir of liquid mercury at its melting point and a colder reservoir extracts 13 J of heat from the mercury and does 5 J of work during each cycle. What is the temperature of the colder reservoir? Mercury melts at 233 K.

A Carnot engine operating between a reservoir of liquid mercury at its melting point and a colder reservoir extracts 13 of heat from the mercury and does 5 of work during each cycle. What is the temperature of the colder reservoir? Mercury melts at 233 .

Explanation / Answer

efficiency = 1- T(cold) / T(hot)

Work done / Heat supplied = 1 - T(cold) /T(hot)

5/13 = 1 - T(cold) / 233

T(cold) = 143 K

so option 2) is the correct answer
