Physical properties of matter are categorized as either Intensive or Extensive:

• Intensive - Properties that do not depend on the amount of the matter present.
  • Color
  • Odor
  • Luster - How shiny a substance is.
  • Malleability - The ability of a substance to be beaten into thin sheets.
  • Ductility - The ability of a substance to be drawn into thin wires.
  • Conductivity - The ability of a substance to allow the flow of energy or electricity.
  • Hardness - How easily a substance can be scratched.
  • Melting/Freezing Point - The temperature at which the solid and liquid phases of a substance are in equilibrium at atmospheric pressure.
  • Boiling Point - The temperature at which the vapor pressure of a liquid is equal to the pressure on the liquid (generally atmospheric pressure).
  • Density - The mass of a substance divided by its volume

• Extensive - Properties that do depend on the amount of matter present.
  • Mass - A measurement of the amount of matter in a object (grams).
  • Weight - A measurement of the gravitational force of attraction of the earth acting on an object.
  • Volume - A measurement of the amount of space a substance occupies.
  • Length - A measurement of the distance from one edge to the opposite edge of a substance

Physical Changes

• Changes in matter that do not alter the identity of the matter itself.
• For example:
  1. Size
  2. Shape
  3. State - solid liquid gas
  4. Dilutions
      
Chemical Changes
1. Changes that do alter the identity of a substance.
2. For example:
   1. Iron rusting
4 Fe(s) + 3 O_2(g) 2 Fe₂O₃ � 3 H₂O
1. Wood burning
2. Copper turning to brass
    
Common Errors
• Ice melting, water freezing, water evaporating, and steam condensing are all examples of a state change.
  • These are physical changes, not chemical.
• Diluting a solution is a physical change, even if the color becomes more faint.
