particle theory
- liquid
- particles are loose
- there are some forces of
attraction between the particles
- the particles are close but free to move past
each other but they do stick together
- particles are always moving
- liquid doesn't keep a definite shape
- can form puddles
- they flow and fill the bottom of the container
- keep the same volume
- liquids won't compress easily because particles are close together
- liquids are quite dense as there are quite a lot of particles in a small volume
- gas
- particles are all over the place
- very weak forces of attraction between particles
- particles are free to move quickly in all directions
- don't keep a definite shape
- will always expand to fill a container
- can be compressed easily
- very low densities
- not very many particles in a large volume
- solid
- particles are packed tight
- strong forces of attraction between particles
- particles are held closely in fixed positions in a
very regular arrangement
- particles can vibtate
- particles don't move from their positions
- all solids keep a definite shape
- solids cant easily be compressed due to particles all
ready being close together
- usually dense as there are lots of
particles in a small volume
