Question

At room temperature the forces of attraction between the particles of solid substances are ____ than those which exist in the gaseous state

Answer 1

Intermolecular forces:

1. Solids are the strongest materials known to exist. Since atoms are packed so closely, any force acting in an inertial frame decreases as the distance between them increases.
2. Therefore, if they are closely packed, they have very little space between them, and Van der Waal forces act more strongly.
3. In a liquid or solid, the average kinetic energy of the particles is low enough that the forces of attraction between them are adequate to keep the particles close to one another.
4. Whereas the kinetic energy between the particles of gases is very low as compared to the force of attraction due to which they are able to move freely.

Therefore, At room temperature, the forces of attraction between the particles of solid substances are stronger than those which exist in the gaseous state.
