To help prevent frost damage, 4.07 kg of 0°C water is sprayed onto a fruit tree. The latent heat of fusion of water is 79.8 kcal/kg.
(a) How much heat will be released by the water as it freezes?
(b) How much would the temperature of the 180-kg tree decrease if it lost this amount of heat, given its specific heat is 0.800 kcal/(kg · °C), and no phase change occurs?
