Intensive and extensive properties

From Free net encyclopedia

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. However, some of the intensive properties are statistical in nature (e.g. viscosity) and are relevant only in aggregate scales.

Examples of intensive properties include:

• temperature
• viscosity
• density
• electrical resistivity
• melting point
• boiling point
• color (in solution)
• flammability
• vagility

Examples of extensive properties include:

• mass
• volume
• entropy
• energy
• electrical resistance
• texture
• pressure
• heat
