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
