Chapter 16, Problem 5DQ

Interpretation Introduction

Interpretation:

The change in the intermolecular forces of a substance needs to be explained when it undergoes change from solid to liquid or liquid to gas. The cause of a phase change needs to be explained.

Concept Introduction :

There are three kinds of matter namely, solid, liquid and gas. There are different types of intermolecular forces depending on the nature of the atoms involved in the bonding.

Solids and liquids contain strong intermolecular forces than gases because the molecules have less space between them or they are packed closely. The solid has more compact form than liquid thus, liquids have weak intermolecular forces as compared to solids.
