Chapter 11, Problem 37E

Interpretation Introduction

Interpretation:

The amount of heat that is required to convert $25.0\text{g}$ of water from $25.0\text{°C}$ to $100.0\text{°C}$ is to be calculated.

Concept introduction:

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 $540\text{cal}/\text{g}$.
