Extensive Property of Matter

Extensive properties will vary from intensive properties in that they do rely on the amount of matter that is present. These properties contain weight, mass, length and volume. All the extensive properties will alter frequently and can be measured by simple tools inside the laboratory.
Extensive properties in many cases are found throughout lab assignments in order to study and calculate intensive properties of a substance. These labs are frequently completed at the starting of introductory chemistry courses in order to introduce students to the significance of the properties of matter.


Extensive: Properties that do rely on the amount of matter present.

Weight: A measurement of the gravitational force of attraction of the earth performing on an object.

Mass: A measurement of the amount of matter in an object (grams).

Volume: A measurement of the amount of space a substance uses up.


An Example of an Extensive Property of Matter is

Extensive properties are the counterparts of intensive properties that are intrinsic to a particular subsystem. Dividing one kind of extensive property by another kind of extensive property will generally give an intensive value. For instance, mass (extensive) divided by volume (extensive) provides density (intensive).

Examples of extensive properties contain:




Gibbs energy

particle number




number of moles

electrical charge

magnetic moment
