Discuss the intermolecular forces v/s thermal interaction.

Explanation

Intermolecular forces tend to keep the molecules close together but internal interaction te4nds to keep them apart and randomise them. (a) In ..solids.., thermal energy is least and intermoleclar forces of attraction are strongest. As a result of this the consitituent particles are involved only in vibrational movement but not in translatory motion. (b) in .. liquieds.. the two types of energies intermediate to those in solids and gases. (c) in .. gases.. intermolecular forces of attraction are weakest and thermaf energy in highest.
