1. A styrofoam cooler (K = .030 W/mo C) has an average surface area of 0.576 m2 and an average thickness of 2.6 cm. There are 4.60 kg of ice at 0oC in the cooler and the outside temperature is 28.0oC. The heat of fusion for water is 3.33E+5 J/kg and the heat of vaporization for water is 2.26E+6 J/kg.
How much heat is required to melt the ice in the cooler?
(in J)
2. About how much time will it take to melt the ice in the cooler?
(in s)
