<P> The ratio of two extensive properties of the same object or system is an intensive property . For example, the ratio of an object's mass and volume, which are two extensive properties, is density, which is an intensive property . </P> <P> The terms intensive and extensive quantities were introduced by Richard C. Tolman in 1917 . </P> <P> An intensive property is a physical quantity whose value does not depend on the amount of the substance for which it is measured . For example, the temperature of a system in thermal equilibrium is the same as the temperature of any part of it . If the system is divided the temperature of each subsystem is identical . The same applies to the density of a homogeneous system; if the system is divided in half, the mass and the volume change in the identical ratio and the density remains unchanged . Additionally, the boiling point of a substance is another example of an intensive property . For example, the boiling point of water is 100 ° C at a pressure of one atmosphere, which remains true regardless of quantity . </P> <P> The distinction between intensive and extensive properties has some theoretical uses . For example, in thermodynamics, according to the state postulate, a sufficiently simple system consisting of a single substance requires only two independent intensive variables to fully specify the system's entire state . Other intensive properties are derived from those two variables . </P>

Is the boiling point of water an extensive or intensive property why do you say so
