On a trip, you notice that a 3.71 kg bag of ice lasts an average of one day in your cooler. What is the average power in watts entering the ice if it starts at -4.82ºC and completely melts to 1.91ºC water in exactly one day? The specific heat of water is 4186 J/kgºC. Specific heat of ice is 2090 J/kgºC and water's heat of vaporization is 334 kJ/kg.
