Physical property

An intensive property does not depend on the size or extent of the system, nor on the amount of matter in the object, while an extensive property shows an additive relationship.

These classifications are in general only valid in cases when smaller subdivisions of the sample do not interact in some physical or chemical process when combined.

In this sense, many ostensibly physical properties are called supervenient.

A supervenient property is one which is actual, but is secondary to some underlying reality.

A cup might have the physical properties of mass, shape, color, temperature, etc., but these properties are supervenient on the underlying atomic structure, which may in turn be supervenient on an underlying quantum structure.
