Chapter 6, Problem 6.50E

Interpretation Introduction

Interpretation:

The explanation corresponding to fact that the slope of the solid-liquid equilibrium line in the phase diagram of ${\text{H}}_{\text{2}}\text{O}$ (Figure 6.5) has a negative value is to be stated.

Concept introduction:

Phase diagram represents the different physical states of a substance at different values of temperature and pressure. In water, the molar volume of solid is greater than the molar volume of the liquid.
