The changes in the physical properties of a system can be used to describe its transformations or evolutions between its momentary states . Physical properties are often referred to as observables . They are not modal properties . Quantifiable physical property is called physical quantity . </P> <P> Physical properties are often characterized as intensive and extensive properties . 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 . </P> <P> Properties may also be classified with respect to the directionality of their nature . For example, isotropic properties do not change with the direction of observation, and anisotropic properties do have spatial variance . </P>
