Density & the Particle Model
Physics: AQA GCSE Higher, topic 3.1.9
Density and the Particle Model
Solids, liquids and gases differ in density. The particle model of matter shows this difference.
Solids
- Solids are the densest state of matter.
- The particles are packed tightly together.
Liquids
- Liquids are less dense than solids but denser than gases.
- The particles in liquids can move around each other.
Gases
- Gases are the least dense state of matter.
- The particles are free to move with negligible (tiny) forces between particles.
