How could you construct a model to represent motion of the particles in solids liquids and gases

The atoms in solids don't move a lot, so you could draw them close together with (()) to show them vibrating.

Atoms in liquids move more than solids, but not as much as gasses. You could draw them further apart with longer arrows.

Atoms in gases move the most, so draw the atoms further apart than liquids and have the arrows be longer than liquids as well.
