1. Physical and Chemical Properties

2. Physical Properties
Physical property- A characteristic that can be observed using one of the five senses
Physical Change- any change that can be reversed.
Common Physical properties-
Color, state of matter, mass, weight, volume, size,

3. Physical Properties
Solubility- Amount of a substance that will dissolve in 100 grams of water
Melting point- The point at which a solid changes to a liquid
Boiling point- The point at which a liquid changes to a gas
Density- the amount of matter in a given object –D=M/V

5. Size Dependent Property
Size dependent property- a property that changes due to size
ex. Mass, weight, length, volume

6. Size Independent Properties
Size independent properties- A property that does not change according to size
ex. Density (mass/volume), Melting point, Boiling point.

7. Behavior Behavior- the way a specific substance reacts
Example-Lodestone is magnetic

8. Chemical Properties
Chemical property- The ability of a substance to undergo change that alters its identity.
Chemical reaction- The change that alters a substances identity.
ex. Burning, rusting

9. Chemical Changes Ways to Identify a chemical reaction Gas given off
Change of color
Change of temperature (chemical reactions usually create heat even if it is a very small amount)
