What is extensive and intensive property

Intensive Properties :Intensive properties are bulk properties, which means they do not depend on the amount of matter that is present. Examples of intensive properties include: Boiling point, Density, State of matter ,Color, Melting point, Odor, Temperature ,Refractive Index ,Luster, Hardness, Ductility, Malleability .

Intensive properties can be used to help identify a sample because these characteristics do not depend on the amount of sample, nor do they change according to conditions.

Extensive Properties: Extensive properties do depend on the amount of matter that is present. An extensive property is considered additive for subsystems.

Examples of extensive properties include: Volume, Mass, Size ,Weight, Length.

The ratio between two extensive properties is an intensive property. For example, mass and volume are extensive properties, but their ratio (density) is an intensive property of matter. While extensive properties are great for describing a sample, they aren't very helpful identifying it because they can change according to sample size or conditions.
