Chapter 22, Problem 20E

Interpretation Introduction

Interpretation:

The comparison between the physical properties of ${\text{H}}_{\text{2}}\text{O}$ and ${\text{D}}_{\text{2}}\text{O}$ are to be explained.

Concept introduction: The normal melting and boiling points of ${\text{D}}_{\text{2}}\text{O}$ are $3.81{}^{\text{ο}}\text{C}$ and $101.42{}^{\text{ο}}\text{C}$ , respectively, versus $0.00{}^{\text{ο}}\text{C}$ and $100.00{}^{\text{ο}}\text{C}$ for ${\text{H}}_{\text{2}}\text{O}$ . Density of ${\text{D}}_{\text{2}}\text{O}$ is greater than that of ${\text{H}}_{\text{2}}\text{O}$ .

To determine: The comparison between the physical properties of ${\text{H}}_{\text{2}}\text{O}$ and ${\text{D}}_{\text{2}}\text{O}$ with explanation.
