A refrigerator has an ice tray compartment at -18.0°C and the room temperature is 29.3°C. The refrigerator can convert 30.2 g of water at room temperature to that many grams of ice at -18.0°C every minute. If the specific heat of ice is 2.09 kJ/kg.K, the specific heat of water is 4.186 kJ/kg.K, the latent heat of fusion is 333.2 kJ/kg and the power required is 82.5 W, what is the COP (cooling) of the refrigerator?
