1. Physical and Chemical Properties

2. Physical Properties
Characteristics that can be observed and measured without changing the identity of the substance.

3. Physical Properties
Density
Melting Point
Boiling Point

4. Density The amount of matter in a given space, or volume D=M/V
Corn Oil
Water
Shampoo
Dish Detergent
Antifreeze
Maple Syrup
The amount of matter in a given space, or volume
D=M/V
Example: Oil & Water
________

5. Changes in States of Matter
Change between solid and liquid
Melting: Solid → Liquid
Freezing: Liquid → Solid
Change between liquid and gas
Vaporization: Liquid → Gas
Evaporation = only on surface of liquid
Boiling = inside and on surface of liquid
Condensation: Gas → Liquid
Change between solid and gas
Sublimation: Solid → Gas

6. Melting and Boiling Point
Melting point → the temperature at which a substance changes from a solid to a liquid
Boiling point → the temperature at which a liquid boils, or changes from a liquid to a gas

7. Other Types of Physical Properties
Taste
Luster (shine)
Flexibility
Heat conductivity
Electrical conductivity
Solubility (ability to dissolve in water.)
Shape
Viscosity (being thick, sticky, and semifluid in consistency)
Ductility (ability to be hammered thin or stretched into wire without breaking)
Malleability (ability to be flattened into thin sheets by hammering or rolling)
Color
Odor
Size
Shape
Texture
Hardness
Magnetic

8. Examples The front board is white. Table tops are a rectangle.
The glass in the windows is an amorphous solid.
The faucet is metallic.
The globe is magnetic.
The odor in the room is pleasant.
The soil in the terrarium is organic.
The fish tank water is not very viscous.
The birds fly. (motion)

9. Chemical Properties
Characteristics that describe the substance’s ability to change into a new substance.

10. Chemical Properties
Reactivity
Combustibility
Flammability

11. Reactivity
The ability of two or more substances to combine and form one or more new substances

12. Combustibility
The ability of a substance to burn

13. Flammability The ease with which a material ignites
(how easily something catches on fire).
