Particle Theory
A theory used to explain the
different properties and
observations of solids, liquids
and gases.
Forces
Tiny forces of attraction hold
the particles together.
Solid Particle
Properties
Fixed arrangement of
particles held closely
together that cannot move
over each other but vibrate.
Liquid Particle
Properties
Held closely together but not
in a fixed arrangement and
can move over each other.
Gas Particle
Properties
Far apart from each other
and free to move about in all
directions.
Molecule
Two or more atoms joined
together in a group.
Diffusion
The movement of particles
spreading out and mixing
with each other without
anything moving them.
Brownian Motion
An erratic movement of small
specks of matter caused by
being hit by the moving
particles that make up liquids
or gases.
