The older definition of element (an element is a pure substance that can't be decomposed chemically) was made obsolete by the discovery of isotopes. There are two different categories into which the physical properties of matter can be classified, namely intensive and extensive properties. These terms were introduced in 1917 by Richard C Tolman. It is a bulk property, meaning that it is a physical property that does not depend on a sample’s size or weight. According to the state pos… ThoughtCo. (noun) Large in extent, range, or amount. The ratio of two extensive properties, however, is an intensive property (e.g., density is mass per unit volume). For example, the freezing point of a substance is a physical property: when water freezes, it’s still water (H 2 O)—it’s just in a different physical state. Examples of extensive properties include mass and volume. An intensive property is a physical quantity whose value does not depend on the amount of the substance for which it is measured. Other intensive properties include color, temperature, density, and solubility. Properties of matter fall into one of two categories. What Is the Densest Element on the Periodic Table? If the property depends on the amount of matter present, it is an extensive property. Recognize the difference between physical and chemical, and intensive and extensive, properties; Molality. Quantity. However, it can become an intensive property if it is considered as a unit value, such as the molar volume (the volume of a mole of the substance). If the property of a sample of matter does not depend on the amount of matter present, it is an intensive property. Which is an intensive property?
