States of Matter

1
States of Matter

• How can we classify matter?

2
States of Matter

• There are three common states of matter solid,
  liquid, and gas

3
Solids

• Definite shape and definite volume
• Particles are packed tightly together and held in
  fixed positions
• Particles vibrate about fixed points

4
Liquids

• Definite volume
• Takes the shape of its container
• Example Milk in a glass vs. Milk in a gallon jug
• Particles can move past each other (fluid)
• Fluid Anything that can be poured
• Particles move more rapidly than in a solid

5
Gases

• No definite shape, takes the shape of its
  container
• No definite volume
• Particles are spread far apart and move past each
  other rapidly

6
Plasma

• Plasma is similar to a hot, ionized gas that
  conducts electricity
• Plasma is considered a fourth state of matter
• Examples lightning, stars (sun), and neon signs

7
Changes of State

• Melting solid becomes a liquid
• Freezing liquid becomes a solid
• Melting and Freezing Points are the SAME
  TEMPERATURE

8
Changes of State

• Condensation gas becomes a liquid
• Boiling liquid becomes a gas
• Condensation and Boiling Points are the SAME
  TEMPERATURE

9
Changes of State

• Sublimation solid becomes a gas
• Example dry ice
• Deposition gas becomes a solid
