Chapter 5, Problem 5.80P

Interpretation Introduction

Interpretation:Calories required for phase change of one mole of ice at $0^0\text{C}$ should be calculated.

Concept Introduction: Figure- $5.19$ is a graph known as Heating Curve that represents total calories of $739\text{ cal}$ for heating $1.0\text{ g}$ of water from $-{20}^0\text{C}$ to ${120}^0\text{C}$ .

A phase change is a change of matter from one physical state to another like solid to liquid or liquid to gas or solid to gas.

Heat of fusion is a heat required to convert $1.\text{0 g}$ of any solid to liquid.
