🔬 The Three States of Matter Compared
All matter is made of particles (atoms or molecules). The state depends on how much energy those particles have and how strongly they are attracted to each other:
- Solid: Particles are held in fixed positions in a regular lattice. They vibrate about fixed points but cannot move past each other. Strong forces of attraction hold them in place. Fixed shape and volume.
- Liquid: Particles are close together but can move past each other. Forces are weaker than in solids. No fixed shape (takes container shape) but fixed volume.
- Gas: Particles have broken free — they move randomly at high speed with large spaces between them. Very weak/negligible forces. No fixed shape or volume — fills any container.
