Question
An ice-making machine inside a refrigerator operates in a
Carnot cycle. It takes heat from liquid water at 0.0 °C and
rejects heat to a room at a temperature of 20.3 °C.
Suppose that liquid water with a mass of 84.2 kg at 0.0 °C
is converted to ice at the same temperature.
Take the heat of fusion for water to be Lf = 3.34×105
J/kg .
How much heat |QH| is rejected to the room?
Express your answer in joules to four significant figures.
