Like other physical properties, an extensive property may be observed and measured without any chemical change (reaction) occurring.Extensive Property ExamplesMass and volume are extensive properties. As more matter is added to a system, both mass and volume changes.Extensive Versus Intensive PropertiesIn contrast to extensive properties, intensive properties do not depend on the amount of matter in a sample. They are the same whether you're looking at a large amount of material or tiny quantity. An example of an intensive property is electrical conductivity. The electrical conductivity of a wire depends on its composition, not the length of the wire. Density and solubility are two other examples of intensive properties. citecite this article Format mla apa chicago Your Citation Helmenstine, Anne Marie, Ph.D. "Extensive Property Definition (Chemistry)."
