Particle theory
|
All matter is made up of tiny fast moving particles
|
|
|
Solid
|
Particles have a strong attraction for each other, packed tightly together and appear to be vibrating in a fixed position ( definite size and shape )
|
|
|
Liquid
|
The particles have a weak force of attraction for each other, so they are packed loosely together. They spend most of their
time vibrating against each other, but occasionally slip past one another into a new position where they continue vibrating – they appear to be vibrating about a position that is moving. (definite size; indefinite shape) |
|
|
Gas
|
The particles of a gas have no attraction for each other, so their
particles are far apart and travel in straight lines between collisions. (indefinite size and shape) |
