Finishing his ginger ale, Ramesh stands at party holding his insulated foam cup that has nothing in it but 0.100 kg of ice at 0℃.

1) In sentence above, How much more heat must be gained to raise the temperature of the melted ice to room temperature of 23.0℃?

2)Under the spreading chestnut tree the village blacksmith dunks a red-hot horseshoe into a large bucket of 22.0℃ water. How much heat was lost by the horseshoe in vaporizing 0.0100 kg of water?

1) 100g*(80 cal/g + 23 C*1.0cal/gC)
= 10,300 cal

2) Additional heat will be transferred to water in the bucket that does not vaporize. You need to know how much water that is. The question is poorly explained. They probably want you to answer 10g*(79C*1.0 cal/gC+540cal/g)
