Chapter 13, Problem 52E

Interpretation Introduction

Interpretation:

You have to determine which state is denser. The solid or liquid with explanation if you know triple point and melting point.

Concept introduction:

If the solid phase is less dense than the liquid phase, then the line separates solid and liquids $\left(\text{fusion curve}\right)$ bends left. $\left(\text{Like water}\right)$

Melting curve is inclined to the solid phase is mole dense than the liquid phase. The line that separates solid and liquid bends right.
