Intensive properties are independent of amount. Identify each as extensive or intensive. WebMay 26, 2009 · Energy (e.g. heat) is a property that depend on the mass or the number of particles in a system. In other words, energy is an extensive property. Physical properties of materials and systems can often be categorized as being either intensive or extensive, according to how the property changes when the size (or extent) of the system changes. According to IUPAC, an intensive quantity is one whose magnitude is independent of the size of the system, … See more An intensive property is a physical quantity whose value does not depend on the amount of substance which was measured. The most obvious intensive quantities are ratios of extensive quantities. In a … See more 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 … See more The general validity of the division of physical properties into extensive and intensive kinds has been addressed in the course of science.
