Consider a 10.0 kg iron box holding 48.0 kg of solid ice. Initially, both the box and the ice are at −35.0 ̊C. You put the box on an electric heater, which has a power output of 9580 Watts. Assume that all of the energy produced by the heater goes into heating the box and the ice. The specific heat of iron is 450.0 J kg−1 ̊C−1, the specific heat of ice is 2108 J kg−1 ̊C−1, and the latent heat of fusion of ice is 333500 J kg−1. (a)How much energy is required to heat the box and the ice to the melting point of ice (0 ̊C)? Give your answer in Joules. (b)How much energy (in Joules) is required to then melt all of the ice?
