Chapter 6, Problem 6.80E

Liquid Freon $\left({\text{CCl}}_{\text{2}}{\text{F}}_{\text{2}}\right)$ is used as a refrigerant. It is circulated inside the cooling coils of older refrigerators or freezers. As it vaporizes, it absorbs heat. How much heat can be removed by $2.00\text{kg}$ of Freon as it vaporizes inside the coils of a refrigerator? The heat of vaporization of Freon is $38.6\text{cal}/\text{g}$.
