1. States of Matter

2. What is matter? Matter is anything that has mass and volume
Mass is the amount of stuff (particles) that make up the substance.
Typically measured with a balance in grams
Volume is the amount of space that matter takes up.
Measurement technique varies with the state of matter
Matter exists in 4 states throughout the universe. 3 primarily on the Earth.

3. States of matter
solid
liquid
gas
plasma

4. solid Has definite mass Has definite volume Holds its own shape
Lowest kinetic energy in particles
Particles the closest together (except water) and vibrate rather than slide around
May or may not have a crystal structure

5. liquid Has definite mass Has definite volume
Takes the shape of the container
A fluid (particles flow)
Particles slide past each other
Has medium kinetic energy in the particles

6. gas Has mass Has no definite volume or shape Fills any container
Particles farthest apart
Has the highest kinetic energy particles
Compressible
Creates pressure
A fluid and flows

7. plasma Highest kinetic energy
Ionized gas (atoms stripped of their electrons.
has mass
No definite volume
Takes shape of container
Created at extremely high temperature or when electricity passes through gas
Responds to magnetic and electric fields
Examples: stars, fire, glowing lights, aurora particles
