Kinetic theory &
Forces between
Particles
- States of matter depend on the forces between particles
- Solid, liquid and gas
- Solid; there is a strong force between particles, pulling them
together. they have a definite shape. solids expand a little when
heated, as the particles begin to vibrate
- Liquid: There is some attraction between them. they
can move past each other but they tend to
stick. They fill a container but have the same
volume
- Gas: There is almost no force between the gas
particles, they are free to move. they dont keep a
definite shape of volume. particles move randomly.
The hotter they get the faster they move
