A refrigerator has a coefficient of performance of 2. The ice (cjce = 2090 J/kg.°C) tray compartment is at -13°C, and the room temperature is 45°C. The refrigerator can convert 4.73 g of water (cwater = 4186 J/kg.°C) at 45°C to 4.73 g of ice at-13°C each minute. What input power (in W) is required? (Answer in 2 decimal places)
