States of Matter
•All matter takes up space and has mass but matter can be found in different states.
States of Matter
•Solid •Liquid•Gas•Plasma
Solids•Solids-has a definite shape and volume
•2 Types of Solids
2 Types of Solids•1. Crystals-when the arrangement of particles are in repeated patterns
•Ex: salt, sugar & snowflakes
•2. Noncrystals- have no crystals. They are called amorphous meaning “having no form”
•Ex: Glass, Plastics & Wax
Liquids
•Liquids- has a definite volume but no definite shape. It flows and takes the shape of its container
Gases
•Gases- does not have a definite shape or volume
Thermal Expansion
•Thermal Expansion- as matter becomes hotter, it expands.
Kinetic Theory of Matter
•Kinetic Theory- constant motion of tiny particles that make up all matter Pg. 488-490
Kinetic Theory of Matter
•Solids- particles are held very close together. The particles can only vibrate (lacks the energy to do anything else)
Kinetic Theory of Matter
•Liquids- Particles can move around each other thus allowing liquids to take the shape of its container
•Gases- Particles have enough energy to separate from one another. Gases can move around and fill in a container.

Solid
-packed together
-Only vibrate
Liquid
-close together
-move around each other
Gas
-separated
-Move anywhere
Plasma
•Plasma- Gaslike mixture of charged particles that exist at extremely high temperatures. Found mostly in stars and sun
Plasma•Plasma makes up much of the matter in the Universe
•Ex: sun, stars, lightning bolts, neon/fluorescent bulbs, & auroras
