What is a solid? |
A state of matter where particles are held close together with strong forces of attraction to form a regular lattice arrangement. Solids have a fixed volume and a fixed shape. |
|
|
|
What is a liquid? |
A state of matter where randomly arranged particles tend to stick closely together but are free to move past each other. Liquids have a fixed volume but no fixed shape. |
|
|
|
What is a gas? |
A state of matter where particles have weak forces of attraction and are therefore free to move within random motion filling the container they are held in. Gases have no fixed volume and no fixed shape. |

Limitations of particle theory |
Particles aren't solid or inelastic and they aren't spheres-they're atoms, ions or molecules The model doesn't show the forces between the particles, so there's no way of knowing how strong they are. The size of the particles and the distances between them aren't necessarily shown to scale |
