Question
To help prevent frost damage, 4.00 kg of $0^\circ\textrm{C}$ 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 $3.35\textrm{ kJ/kg}\cdot\textrm{C}^\circ$, and assume that no phase change occurs.
1. $1.34\times 10^{6}\textrm{ J}$
2. $1.99\textrm{ C}^\circ$
