Intensive and Extensive properties Thermodynamics Physics
𝑰𝒏𝒕𝒆𝒏𝒔𝒊𝒗𝒆 𝑷𝒓𝒐𝒑𝒆𝒓𝒕𝒚
An intensive property is a property of matter that does not change as the amount of matter changes.
An intensive property is a bulk property, meaning that it is a local physical property of a system that is independent of the system size or the amount of material in the system.
If the property is unchanged by altering the sample size, it's an intensive property.
Example of Intensive Property
Density, Temperature , Melting point, Hardness, Color,
The density (Intensive) of water is approximately 1g/mL whether you consider a drop of water or a swimming pool, but the mass (Extensive) is different in the two cases.

An extensive property is a physical quantity whose value is proportional to the size of the system it describes, or to the quantity of matter in the system.
For example, the mass of a sample is an extensive quantity; it depends on the amount of substance
Other examples are
Volume, amount of substance, Energy(E), mass, Heat Capacity (Cp)
Dividing one extensive property by another extensive property generally gives an intensive value—for example: mass (extensive) divided by volume (extensive) gives density(intensive).
