Calculate the Heat Released When 25

Calculate the heat released when 25.0 g of water at 0 °C crystallizes to ice at the same temperature.The specific heat of water is 1.00 cal/(g x °C) ;the heat of fusion is 80.0 cal/g;and the heat of vaporization is 540.0 cal/g.

A) 3.20 cal
B) 21.6 cal
C) 25.0 cal
D) 2.00 x 103 cal
E) 1.35 x 104 cal
