| What happens when we heat up a solid | particles vibrate with a greater amplitude |
| Structure of liquids | - particles close together - move and flow randomly past one another - fixed volume but can change shape |
| What happens when we heat a liquid | the speed of the particles increase |
| Structure of gases | - particles far apart - move randomly in all directions - can change shape and volume |
| What happens when we heat a gas | the speed of particles increases |
