Chapter 11, Problem 138AP

Interpretation Introduction

Interpretation:

On the basis of graphical representation, the effect on dichlorodifluoromethane gas when compressed to $\text{18 atm}$ and at $\text{20}°\text{C}$, is to be discussed.

Concept introduction:

A phase diagram is a graph that represents the solid, liquid, and gaseous phases of a substance, at different values of pressure and temperature.

The lines are the boundary between the two phases and represent the conditions under which the two phases are in equilibrium.

At the triplepoint, the three-phase boundaries meet other.

The temperature at which a substance changes from a liquid to vapour phase at $\text{1atm}$

is the normal boiling point.

The temperature at which a substance changes from a solid to liquid phase at $\text{1atm}$

is the normal melting point.

The temperature at which a substance changes from a liquid to a solid phase at $\text{1atm}$

is the normal freezing point.
