water's heat of fusion is 80 cal/g and is specific heat is 1.0 cal/g degree celcius. Some velmobile set have been designed to hold ice packs inside their cushions. if you started the ride with ice packs that held 1900 g of frozen water at 0 degree celcius,and the temperature of water at the end was 32 degrees celcius, how many calories of heat energy was absorbed? Express our answer numerically in calories using two significant figures.
