* In a solid:
  * The particles are **closely packed**
  * The particles **vibrate** about fixed positions

  \
* Solids have:
  * A definite **shape** (they are **rigid**)
  * A definite **volume**
* In a solid:
* The particles are **closely packed**
* The particles **vibrate** about fixed positions

* Solids have:

* In a liquid:
  * The particles are **closely packed**
  * The particles can **flow** over one another

  \
* Liquids have:
  * No definite shape – they are able to **flow** and will take the shape of a container
  * A definite **volume**
* In a liquid:
* The particles are **closely packed**
* The particles can **flow** over one another

* In a gas:
  * The particles are **far apart**
  * The particles move **randomly**

  \
* Gases have:
  * No definite shape 
  * No fixed volume
  * \
* Gases are highly **compressible**, this is because:
  * There are large **gaps** between the particles
  * It is easier to **push** the particles closer together than in solids or liquids
