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 21.6 ∘C. Suppose that liquid water with a mass of 77.6 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 . |QH|

| Q H | = 2.797×107 J

How much energy E must be supplied to the device?
