Chapter 12, Problem 12.17P

Interpretation Introduction

Interpretation:

The macroscopic property that can distinguish A from B is to be determined.

Concept introduction:

The phase diagram is the combination of liquid-gas, solid-liquid, and solid-gas curves and determines the effect of temperature and pressure on the phase of as a substance. The general phase diagram can be represented as follows:

Here,

BD is the fusion curve.

AB is the sublimation curve.

BC is the vaporization curve.

When a solid phase is converted into a liquid phase and when a liquid freeze it changes to a solid phase. The phase changes can be expressed as follows:

$\text{Solid}\underset{\text{Freezing}}{\overset{\text{Melting}}{\rightleftarrows }}\text{Liquid}$
