1. PROPERTIES OF
MATTER
PHYSICAL AND
CHEMICAL

2. PHYSICAL PROPERTIES: can be used: -to identify a material,
-to choose a material for a specific
purpose,
to separate the substances
in a mixture

3. EXAMPLES OF
PHYSICAL
PROPERTIES

4. VISCOSITY The tendency of a liquid to keep from flowing:
RANK IN ORDER of
Increasing viscosity.

5. CONDUCTIVITY
A materials ability to allow
heat to flow through it.
Rank in order of increasing
Conductivity.

6. MALLEABILITY The ability of a solid to be hammered without shattering.
Rank in order of increasing malleability.

7. Melting or Boiling Point
The temperature at which the state
Of matter changes (solid to liquid,
Liquid to gas.)
Which has a higher melting point?

8. DENSITY ratio between mass and volume
DENSITY ratio between mass and volume. Can be used to test purity, since
all substances have specific,
unchanging densities. It is a
measure of how much mass is in
a certain volume.

9. CHEMICAL PROPERTIES Any ability to produce a Change in the composition
Of matter. Can be observed
when substances are
changing into different
substances.

10. FLAMMABILITY-ability to
EXAMPLES:
FLAMMABILITY-ability to
Burn in the presence of oxygen.
REACTIVITY-how readily a
substance combines chemically
with other substances.

11. HOW TO RECOGNIZE
A CHEMICAL CHANGE
A NEW substance will ALWAYS
be formed.
Change in color –
Production of a gas
Formation of a precipitate
Change in energy (heat or light)
