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 f a 180-kg tree rise if it absorbed the heat released in part (a)? Assume that the specific heat capacity of the tree is 2.5 x 103 J/(kg . C°) and that no phase change occurs within the tree itself.
