EXTENSIVE AND INTENSIVE PROPERTIES

locument will
Physical properties can be extensive or intensive,
and many physical properties are measurable.
Mass and volume are extensive properties. Mass is
a measurement of the amount of matter an object
has. Volume is a measurement of how much space
a quantity of matter occupies. Density is an intensive
properly. It is a measurement of how much matter
is in a certain volume. The table lists examples of
extensive and intensive properties.
A chemical property is observed only when a chernical
change to matter occurs. Chemical change requires a
chemical reaction. In chemical reactions, the particles
of substances are rearranged to form new substances
In contrast, a physical change is a change that does not
result in a new substance being formed.
