Interpretation Introduction

Interpretation:

An explanation corresponding to the fact that ${\text{CO}}_{\text{2}}$ is a soft, low-melting solid (dry ice), whereas ${\text{SiO}}_{\text{2}}$ is a hard solid (sand) by using the concept of interparticle forces is to be stated.

Concept introduction:

The forces which initiates the interaction between the atoms of a molecule is known as the intermolecular forces. The intermolecular forces are of two types; forces of attraction and forces of repulsion. The name of the intermolecular forces are, ion-dipole forces of attraction, Van der Waals forces, hydrogen bonding, dispersion forces and others.
