States of matter at particle level

States of matter at particle level

Particle diagrams of solid, liquid, and gas showing close regular particles in a solid, close random particles in a liquid, and widely spaced fast-moving particles in a gas

The kinetic particle model says that all matter is made of tiny particles that are always moving. The state of a substance depends on particle arrangement, spacing, and motion.
