Ice of mass 11.0 kg at 0.00° C is placed in an ice chest. The ice chest has 3.10 cm thick walls of thermal conductivity 1.00 x 10^-5 kcal/s · m · C° and a surface area of 1.40 m2.
(a) How much heat must be absorbed by the ice before it melts?
(b) If the outer surface of the ice chest is at 33.0° C, how long will it take for the ice to melt?
