Chapter 11, Problem 39E

Interpretation Introduction

Interpretation:

The amount of heat that is required to convert $\text{115}\text{g}$ of ice to steam from $0.0\text{°C}$ to $100.0\text{°C}$ is to be calculated.

Concept introduction:

When a substance change its state from solid to liquid, then the amount of heat needed to melt $\text{1}\text{.00}\text{g}$ of substance is known as heat of fusion $\left({\text{H}}_{\text{fusion}}\right)$.

The heat of fusion for water is $80.0\text{cal}/\text{g}$.

At boiling point, the substance changes its state from liquid to vapor form. The heat of vaporization is the amount of heat needed to vaporize $\text{1}\text{.00}\text{g}$ of a substance.

The heat of vaporization for water is $540\text{cal}/\text{g}$.
