In chemistry what is an Extensive property & an Intensive property?

Question

Please define both for me and give me some examples of each. I CANNOT find these in my reading materials and its not obvious to me. Please help!

Answer 1

In physics and chemistry an intensive property of a system is a physical property of the system that does not depend on the system size or the amount of material in the system. By contrast, an extensive property of a system does depend on the system size or the amount of material in the system.
Examples of intensive properties include:

* temperature
* viscosity
* density
* electrical resistivity
* melting point
* boiling point
* pressure
* spectral absorption maxima (in solution)
* flammability

Examples of extensive properties include:

* mass
* volume
* entropy
* energy
* electrical resistance
* texture
* heat

Answer 2

Intensive Property Definition

Answer 3

1

Answer 4

Extensive property means a Quatitive and Intensive means Qualitative. In other words Extensive property are the properties that depend on the mass and Intensive property means does not depend on mass of the system

Answer 5

Define Extensive

An intensive 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 in thermal equilibrium 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 the system is divided in half, the mass and the volume change in the identical ratio and the density remains unchanged. Some intensive properties, such as viscosity, are empirical macroscopic quantities and are not relevant to extremely small systems Examples of intensive properties include: temperature chemical potential density specific gravity viscosity velocity electrical resistivity spectral absorption maxima (in solution) specific energy specific heat capacity hardness melting point and boiling point pressure ductility elasticity malleability magnetization concentration color flammability An extensive property is a physical quantity whose value is proportional to the size of the system it describes. Such a property can be expressed as the sum of the properties for the separate subsystems that compose the entire system.[citation needed] Extensive properties are the counterparts of intensive properties, which are intrinsic to a particular subsystem and remain constant regardless of size. Dividing one type of extensive property by a different type of extensive property will in general give an intensive value. For example, mass (extensive) divided by volume (extensive) gives density (intensive). Examples of extensive properties include entropy enthalpy energy mass particle number resistance stiffness momentum number of moles volume Examples of perceptions related to an intensive physical property: Temperature: in this case all observers will agree which is the hotter of two objects. Loudness of sound; the related physical property is sound pressure level. Observers may disagree about the relative loudness of sounds with different acoustic spectra. Hue of a solution; the related physical property is the position of the spectral absorption maximum (or maxima). Examples of perceptions related to an extensive physical property: Color of a solution: The related physical property is the transmission or absorption spectrum

Answer 7

Extensive property is the property of the system which is independent of the system size or the amount of matter in the system.
Intensive property is one which is independent of the system size.
For example, mass, internal energy would be extensive properties whereas density, temperature would be intensive.

Answer 8

Intensive property is non-dependent upon sample size, whereas an extensive property is dependent upon the sample size.

Example (as you asked for one!): whether you have 5 grams or 50 kilograms of water, it still freezes at 0C and boils at 100C. This is an intensive property.

But the volume that 5 grams or 50 kilograms of water occupies is an extensive property because it depends on the size of the sample (obviously the larger amount occupies more volume).

Let me know if this answers your question!

Answer 9

Intensive properties (temperature, pressure) do not depend upon the sample size. Extensive properties (mass, volume) depend upon sample size. Two identically sized portions of a solution are prepared. One portion is then arbitrarily subdivided into three subportions. For intensive properties, the value of the property for each subportion is the same. For extensive properties, the sum of the values of the property for the subportions equals the value for the whole portion.
