PROPERTIES
OF MATTER
Physical Property
A characteristic of a substance that can be
observed or measured without changing the
identity of the substance.
Physical properties of matter include color,
hardness, malleability, solubility, electrical
conductivity, density, melting point, and
boiling point.
Physical Property
Physical properties can be extensive
or intensive.
Extensive Properties vary with the
amount of the substance while
Intensive Properties do not.
Activity
Classify the following properties into intensive (IP)
or extensive properties (EP).
1)Taste IP 7) Volume EP
2)Hardness IP 8) Melting point IP
3)Shape EP 9) Mass EP
4)Density IP 10)Luster IP
5)Boiling Point IP 11) Color IP
6)Length EP
Chemical Property
A chemical property describes the
ability of a substance to undergo a
specific chemical change.
To identify a chemical property, we
look for a chemical change. A chemical
change always produces one or more
types of matter that differ from the
matter present before the change.
Chemical Property
For example, hydrogen has the
potential to ignite and explode
given the right conditions.
Metals in general have the
chemical property of reacting
with an acid.
Zinc reacts with hydrochloric
acid to produce hydrogen gas.
Activity
Identify the following situations if it exhibits a physical
property or a chemical property of matter.
Gallium metal melts at 30 oC. PHYSICAL PROPERTY
A green banana turns yellow when it ripens. CHEMICAL PROPERTY
Gold is shiny. PHYSICAL PROPERTY
Iron metal rusts.
CHEMICAL PROPERTY
A dry piece of paper burns.
CHEMICAL PROPERTY
Mercury is a very dense liquid.
