INTENSITIVE QUANTITY

 

An intensive quantity is a physical quantity whose value does not depend on the amount of the substance for which it is measured. It is the counterpart of an extensive quantity. For instance, the mass of an object is an extensive quantity, because it depends on the amount of that substance being measured. Density, on the other hand, is an intensive property of the substance. 

a

physical quantity is a physical property that can be quantified. This means it can be measured and/or calculated and expressed in numbers.

 The

density of a material is defined as its mass per unit volume.



Examples of intensive properties include: temperature chemical potential density specific gravity viscosity velocity electrical resistivity 

◦ Intensive - Properties that do not depend on the amount of the matter present.  Color Odor Luster - How shiny a substance is. Malleability - The ability of a substance to be beaten into thin sheets. Ductility - The ability of a substance to be drawn into thin wires. Conductivity - The ability of a substance to allow the flow of energy or electricity. Hardness - How easily a substance can be scratched. Melting/Freezing Point - The temperature at which the solid and liquid phases of a substance are in equilibrium at atmospheric pressure. Boiling Point - The temperature at which the vapor pressure of a liquid is equal to the pressure on the liquid (generally atmospheric pressure).

Extensive quantity

An

extensive quantity is a physical quantity whose value is proportional to the size of the system it describes. Extensive quantities are the counterparts of intensive quantities, which are intrinsic to a particular subsystem and remain constant regardless of size. Dividing one type of extensive quantity by a different type of extensive quantity will in general give an intensive quantity.

◦ Extensive - Properties that do depend on the amount of matter present.  Mass - A measurement of the amount of matter in a object (grams). Weight - A measurement of the gravitational force of attraction of the earth acting on an object. Volume - A measurement of the amount of space a substance occupies. Length 
