The distinction between intensive and extensive properties has some theoretical uses. For example, in thermodynamics, the state of a simple compressible system is completely specified by two independent, intensive properties, along with one extensive property, such as mass. Other intensive properties are derived from those two intensive variables.
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.
For example, mass is an intrinsic property of any physical object, whereas weight is an extrinsic property that depends on the strength of the gravitational field in which the object is placed. Applications in science and engineering
An intensive property of a substance defined as mass per unit volume and expressed by the equation d = m/V. denticity The number of donor groups in a single ligand that bind to a central atom in a coordination complex. deposition The settling of particles within a solution or mixture. depression of freezing point See freezing-point depression ...
For example, in a quark–gluon plasma or other QCD matter, at every point in space there is a chemical potential for photons, a chemical potential for electrons, a chemical potential for baryon number, electric charge, and so forth. In the case of photons, photons are bosons and can very easily and rapidly appear or disappear. Therefore, at ...
The magnitude of an intensive quantity does not depend on the size, or extent, of the object or system of which the quantity is a property, whereas magnitudes of an extensive quantity are additive for parts of an entity or subsystems. Thus, magnitude does depend on the extent of the entity or system in the case of extensive quantity.
An extensional definition gives meaning to a term by specifying its extension, that is, every object that falls under the definition of the term in question.. For example, an extensional definition of the term "nation of the world" might be given by listing all of the nations of the world, or by giving some other means of recognizing the members of the corresponding class.
Feedbacks are also possible between rates of erosion and the amount of eroded material that is already carried by, for example, a river or glacier. [5] [6] The transport of eroded materials from their original location is followed by deposition, which is arrival and emplacement of material at a new location. [1]
