Wikipedia Meaning and Definition on 'Extensive'

In the physical sciences, an intensive property (also called a bulk property), is a physical property of a system that does not depend on the system size or the amount of material in the system: it is scale invariant. By contrast, an extensive property of a system is directly proportional to the system size or the amount of material in the system.

Some intensive properties, such as viscosity, are empirical macroscopic quantities and are not relevant to extremely small systems.

For example, density is an intensive quantity as it does not depend on the quantity, while mass and volume are extensive quantities. Note that the ratio of two extensive quantities that scale in the same way is scale-invariant, and hence an intensive quantity.

An intensive quantity (also variable or 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 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 divided in half, the mass and the volume change in the identical ratio and the density remains unchanged.
