Kinetic Particle Theory

1) States of Matter

Solid- Fixed Shape, Fixed Volume, Cannot be compressed

Liquid- Not Fixed Shape, Fixed Volume, Cannot be compressed

Gas- Not Fixed Shape, Not fixed Volume, Can be compressed

2) Kinetic Particle Theory

The Kinetic Particle Theory states that all matter is made up of tiny particles and that these particles are in constant, random motion. Moving particles have kinetic energy, thus the name kinetic particle theory.

The Kinetic Particle Theory:

1) Describes the states of matter

2) Explains the differences in the properties of solids, liquids and gases

3) Explains the change of state 

Example:

Air is made up of tiny dust particles that move around. The dust seen in a beam of light is the result of air particles moving and bumping into dust. Air particles are too small to be seen by the naked eye, therefore we can only see the due moving.
