Question

How does the intermolecular force exist in particles of matter?

Answer 1

Answer:

A change in phase may occur when the energy of the particles is changed. There are spaces between particles of matter. ... There are attractive forces between atoms/molecules, and these become stronger as the particles move closer together. These attractive forces are called intermolecular forces.

Answer 2

The molecules of a gas move apart when they collide. The average kinetic energy of the particles in a liquid (or solid) is small enough that the forces of attraction between them is sufficient to hold the particles close together. The molecules in a liquid (or solid) do not move apart.
