1 Physical/Chemical Properties/Changes and Intensive/Extensive Properties Notes 8/30/12

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, shapeor 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
