Matter Can Exist in Four Phases

• 1. Solid
• 2. Liquid
• 3. Gas
• 4. Plasma

3
Solids

• Have a definite shape
• Have a definite volume
• Tiny particles that make up a solid are packed
  very closely together
• Particles are able to vibrate!
• A solid is able to keep its definite shape.

4
Liquids

• A. Have no definite shape.
• B. Have a definite volume.
• C. Particles are free to move not packed as
  tightly as a solid.
• D. Take the shape of a container. What do you
  think would happen if you tried to pour one liter
  of water into a half-liter bottle? (The water
  will overflow)

5
Liquids

• Viscosity
• The resistance of a liquid to flow.
• Honey has a high viscosity compared to water.
• Honey flows more slowly than water.
• Automobile oil has a high viscosity.

6
Gases

• Have no definite shape.
• Have no definite volume.
• Fills all available space in a container.
• Particles tend to spread far out from one
• another, but they can be pushed close
  together such as in
• -Pumping air into a bicycle tire.
• -Blowing up a balloon.

7
Gases

• If allowed, gases will expand without limit.
• If not for the pull of gravity, gases would
  expand into space.

Solids, Liquids, and Gases

Plasma

• Rare on Earth, but one of the most
• common phases found in the universe.
• High in energy, so very dangerous to
• living things.
• Stars such as the sun contain matter in the
  plasma phase.

11
Plasma

• The negatively charged electrons (yellow) are
  freely streaming through the positively charged
  ions (blue).
