14.3 Exercise 24

Avg difficulty 2.5

To help prevent frost damage, 4.00 kg of 0ºC0º \text{C} water is sprayed onto a fruit tree.

(a) How much heat transfer occurs as the water freezes?

(b) How much would the temperature of the 200-kg tree decrease if this amount of heat transferred from the tree? Take the specific heat to be 3.35 kJ/kg⋅ºC3 .\text{35}\textrm{ }\text{kJ}/\text{kg} ⋅º \text{C}, and assume that no phase change occurs.
