John decides to make ice using a Carnot refrigerator that takes heat from water at 0°C to a room at 30°C. Suppose 200 g of water at 0°C are converted to ice at 0°C by the refrigerator. Calculate the mechanical energy that must be applied to the refrigerator in J. The latent heat I fusion of water is L-3.34x10° J/kg. Remember the definition of the coefficient of performance K and first calculate K.
