Difference Between Intensive and Extensive Properties

There are different types of physical properties of matter. They are intensive and extensive properties. These terms were introduced in 1917 by Richard C Tolman. Also, the ratio of two extensive properties is intensive property.

Example: the ratio of mass and volume is equal to the density.

Mass/Volume = Density

Mass and volume are extensive properties, density is intensive property.

Intensive Properties

The word intensive was derived from “intensivus”. Intensive properties are independent of the amount of substance present. Or they are bulk properties. Characteristic doesn’t change. The size of intensive properties does not change. Density, temperature, pressure etc are some of the examples of intensive properties.

Extensive Properties

The word extensive was derived from “extensivus”. Extensive properties are dependent on the amount of substance present. They can easily be identified. Size of Extensive properties changes. It can be computed. Volume, size, mass, length, weight are some of the examples of extensive properties.

To make you understand how intensive and extensive properties are different from each other, here are some of the major differences between intensive and extensive properties:

Difference between Intensive and Extensive properties
INTENSIVE EXTENSIVE
Independent property Dependent property
Size does not change Size changes
It cannot be computed It can be computed
Can be easily identified Cannot be easily identified
Example: melting point, color, ductility, conductivity, pressure, boiling point, luster, freezing point, odor, density, etc Example: length, mass, weight, volume

These were some of the important differences between extensive and intensive properties.

FAQs

1. Which is an intensive property?
Ans: The intensive property is a product property that does not change as the number of matter increases. It is a bulk property, meaning that it is a physical property that does not depend on a sample’s size or weight.

2. Why are intensive and extensive properties important?
Ans: Mass and weight, for example, are extensive properties, but their ratio (density) is an intensive product property. Although extensive properties are good to describe a sample, they are not very helpful to classify it as they may change depending on sample size or conditions.

3. What are intensive and extensive properties in thermodynamics?
Ans: The concentrated property is independent of the mass amount. The value of a large property varies with the volume directly. Examples of intensive properties are temperature, pressure, total volume, and density.

4. What is extensive property in thermodynamics?
Ans: There are two different categories of thermodynamic properties: intensive properties and extensive properties. An extensive property is any property depending on the size (or extent) of the system being considered. Volume is a case in point.

5. What is meant by extensive property?
Ans: A large property is a material property that varies as the number of matter increases. Like other physical properties, without any chemical alteration (reaction) occurring, an extensive property can be detected and measured.
