2.- To help prevent frost damage, fruit growers sometimes protect their crop by spraying it with water when overnight temperatures are expected to go below freezing. When the water turn into ice during the night, heat is released into plants, thereby giving a measure of protection against the cold. Suppose a grower sprays 7.2 kg of water at 0°C onto a fruit tree. a) How much heat is released by the water when it freezes? b) How much would the temperature of a 180-kg tree rise if it absorbed the heat released in part a)? Assume that the specific heat of the tree is 2.5 × 10³ J/(kg°C).
