What is the difference between a solid, liquid, and gas according to the particle theory of matter?
Solid = definite shape, definite volume, particles are close together, particles vibrate in place.
Liquid = indefinite shape, definite volume, particles are close but flow freely over each other.
Gas = indefinite shape, indefinite volume, particles are far apart and move randomly.
