States Of Matter Particles
Key knowledge — States Of Matter Particles
Key facts & rules
- Solid: particles close together in a regular lattice, vibrate in fixed positions.
- Liquid: particles close together but random arrangement, free to move past each other.
- Gas: particles far apart, random, move rapidly in all directions.
- Melting: solid → liquid (at melting point). Boiling: liquid → gas (at boiling point).
- Condensation: gas → liquid. Freezing/Solidification: liquid → solid. Sublimation: solid → gas directly.
- Kinetic theory: particles are always moving; higher temperature = higher average kinetic energy.
- Diffusion: particles spread from high to low concentration. Faster in gases than liquids.
- Brownian motion: random movement of particles in a fluid, caused by collisions with invisible molecules.

About States of Matter & Particles on IGCSE 0653
The particle model explains the properties of solids, liquids and gases. Particles in different states have different arrangements, separations and movement. Changes of state involve energy changes without new substances forming.
What's covered:
- Particle arrangement in solids, liquids and gases
- Changes of state: melting, boiling, condensation, sublimation
- Diffusion in gases and liquids
- Kinetic theory of gases
- Brownian motion
