Particle arrangement in the three states

Particle arrangement in the three states

Particle arrangement in solids, liquids, and gases: solids are regular and closely packed, liquids are close but irregular, and gases are widely spaced and random.

Every substance is made of particles that are always moving. In a solid, particles are very close together in a fixed, regular arrangement and vibrate about fixed positions.
