Chapter 11, Problem 96QP

Interpretation Introduction

Interpretation:

A rough phase diagram of ${\text{SO}}_{\text{2}}$ using the given data is to be sketched.

Concept Introduction:

A phase diagram is a graph that represents the solid, liquid, and gaseous phase of a substance at different pressures and temperatures.

The lines are the boundary between two phases and represent theequilibrium between two phases.

The three phase boundaries meet at the third point.

The temperature at which a substance changes from a liquid phase to vapor phase at $\text{1atm}$ is called the normal boiling point.

The temperature at which a substance changes from a solid phase to liquid phase at $\text{1atm}$ is called the normal melting point

The temperature at which a substance changes from a liquid phase to solid phase at $\text{1atm}$ is called the normal freezing point.
