  1. Physical/Chemical Properties/Changes and Intensive/Extensive Properties Notes8/30/12

  2. Chemical Property- The ability of a substance to change into another new substance- This type of property can only be observed through experimentation- Examples include flammable, corrosive, oxidizer, highly reactive, inert (not reactive)

  3. Physical Properties - A quality that a substance has that can be observed without changing what It is made of.- This type of property can be determined using your five senses- Examples include color, odor, state of matter, melting/boiling point, solubility

  4. Chemical Changes- The action of one substance changing into another new substance with new properties- Clues this occurred include color change, heat/light being produced, a solid or gas formed from liquids- Examples include burning, rusting, milk souring, decaying, tarnishing

  5. Physical Changes- A change which alters the size, shape or state of a substance, but does not change what it is made of.- If you know that you have the same molecules at the end, just arranged differently it is this type of change.- Examples include tearing, melting, boiling, dissolving diluting, breaking

  6. Intensive Properties- A quality that does not change based on the amount of a substance that is being observed- If you have a little or a lot this property stays the same- Examples include color, melting/boiling point, density

  7. Extensive Properties- A quality that changes based on how much of a substance is being observed- If more or less would make the observation different, it would be this type of property- Examples include mass, volume, size, shape
