Heat calcualate?

Question

how much heat would be required to convert 10 grams of ice at 0 degree celcius to 10 gram of water at 75 degree celcius.The following values may be use to you:
Specific heat of water=1 cal/g -degree celcius
Heat of vaporization of water=540 cal/g
Heat of fusion of water = 80 cal/g

Answer 1

Don't worry about the vaporization. Use a covered container. The heat is required to melt the ice and heat it from 0 to 75 deg C.
Total heat = 10grams (540+75(1))= 6150 calories.
