SOLIDS

• A solid is a form of matter that has the
  following properties
• Definite Shape
• Definite Volume
• Not easily compressed
• The particles in a solid are packed tightly
  together in an orderly configuration.
• Examples wood, rock

4
Types of Solids

• Crystal
• Describes a solid that has a repeating structure
• Example NaCl
• Amorphous Material
• Describes a solid that has a random arrangement
  of atoms
• Example rubber, plastic, asphalt, glass

5
LIQUIDS

• A liquid is a form of matter that has the
  following properties
• Indefinite Shape
• Definite Volume
• Not Easily Compressed
• Flows
• The particles in a liquid are in close contact
  with one another, but are not arranged in an
  orderly configuration.
• Examples apple juice, milk

6
GASES

• A gas is a form of matter that has the following
  properties
• Indefinite Shape
• Indefinite Volume
• Easily Compressed
• The particles of a gas are farther apart than in
  either a solid or a liquid and there is no
  orderly arrangement.
• Examples steam, oxygen
