Extensive Property?

Postby veneziaramirez 3I » Thu Feb 08, 2018 5:04 am

What does it mean for something to be an extensive or intensive property?

An extensive property is dependent on the amount of matter present, while an intensive property does not depend on this amount. An extensive property would be heat capacity, for example. This is because the larger the amount of the substance, the more heat that is required to raise its temperature.

To build on this, intensive properties would be like density and melting/boiling point of an element, which remain the same despite the amount of matter present in a sample.

As others have mentioned, an intensive property is a property that is not dependent on the size of a system or the amount of material present within the system. Intensive properties include density (which is the ratio of mass over volume) and the standard reduction potential, which remains the same value regardless of how many times a reaction occurs. On the other hand, an extensive property is one that does depend on the amount in or size of a system; an example would be volume, which varies depending on mass.
