Study Notes
Particles and States of Matter
- Almost everything is made of particles, which can be atoms, molecules, or ions.
- Particles behave differently in solids, liquids, and gases.
- The particle model explains the differences between solids, liquids, and gases.
Solids
- Many materials are solid, including paper, bricks, wood, metal, and ice.
- Particles in solids are very close together and cannot usually be compressed or squushed.
- Forces of attraction between particles hold them together and keep them in place.
- Particles in solids are arranged in a regular way.
- Particles in solids move only by vibrating about a fixed position, giving solids a fixed shape.
Water
- Water exists as a solid, liquid, and gas.
- Solid water is also known as ice.
- Gaseous water is also known as water vapor.
