Question
help with both please
Calculate the heat reloaded when 25.0 g water at 0 degree C crystallizes to ice at the same temperature. The specific heat of water is 1.00 cat/(g times degree C); the heat of fusion Is 80.0 cal/g; and the heat of vaporization is 540.0 cal/g. 3.20 cal 21.6 cal 25.0 cal 2.00 times 10^3 cal 1.35 times 104 cal Calculate the heat required to convert 10.0 g of water at 100 degree C to steam at 100 degree C. The specific heat of water is 1.00 cal/g times degree C); the heat of fusion is 80.0 cal/g; and the heat of vaporization is 540.0 cal/g. 8.0 cal 10.0 cal 54.0 cal 8.00 times 10^2 cal 5.40 times 10^3 cal
