STATES OF MATTER

=Particle Theory= All matter is made up of tiny particles too small to be seen. ==States of Matter== ===Matter exists in three possible states: Solids, Liquids & Gasses=== [image:http://i.imgur.com/TQQ9JyQ.png?1] '''Solids''': • The particles in solids are packed together tightly in a fixed pattern. • The particles in a solid cannot move from their spot, they can only vibrate. • When a solid is heated, the particles vibrate faster, causing the solid to expand very slightly.
