Chemical Properties of
Matter
IAN pg. 29
Main Ideas
1. Freezing Point
2. Melting Point
3. Evaporation
4. Sublimation
5. Boiling Point
6. Condensation
7. Dew Point
Objective
Identify chemical
properties and
changes in
matter using
demonstrations,
notes and
collaboration.
II.
Changes of states of matter are
physical changes.
A. Freezing Point: The
temperature when a Liquid
turns into solid.
B. Melting Point: The temperature
when a Solid turns into a liquid.
C. Evaporation: liquid to a gas.
Occurs over a wide range
of temperatures.
D. Sublimation: Solid to a gas.
E. Boiling Point:. Specific
Temperature at which a Liquid
turns into a gas.
F. Condensation: Gas to a liquid.
Dependent upon temperature
& humidity.
G. Dew Point – The temperature
at which condensation will
occur. (rain)
Section 2-3
III.
Identifying substances
A. Some physical properties
identify substances better
than others.
Good identifiers: density, heat
conductivity, solubility, electric
and magnetic properties.
B. Separating mixtures
1. Filtering: Sand from water
2. Drying: Salt from water
3. Magnetic: Metal from
non-metal
Sewage treatment plants use
mixture separation.
