Extensive properties depend on the amount of substance. The volume of a sample is an extensive property: 1000 grams of water takes up more volume than 10 grams of water. Mass is also an extensive property.
Below is a list of extensive properties:
- Mass: A measurement of the amount of matter present in an object.
- Weight: A measurement of the gravitational force of attraction of the earth acting on an object. It is given by product of the mass of the object by the acceleration due to gravity W = m * g. The SI unit is Newton (N) or kilogram-meters per second squared.
- Volume: A measurement of the amount of space a substance occupies. Volume is the space actually occupied by an object or the bulk of some substance.
- Length: The linear extent in space from one end to the other. The SI unit of length is meter (m).
In the example picture below, the balance scale measures the mass of the beaker and liquid, while the beaker measures the volume of the liquid it contains.
