Intensive vs extensive property

Postby Felicia Fong 2G » Fri Jan 12, 2018 10:40 pm

What is the difference between intensive and extensive properties? Why is it more useful to have intensive properties?

An intensive property is one that is independent of the size of the sample. Examples include density or temperature. An extensive property, on the other hand, depends on the size of the sample. Examples of this are volume or enthalpy. Intensive properties might be helpful because they stay constant even when the sample changes in size. We cannot say the same of extensive properties.

Yes! To add on to what Lisa said, intensive properties only depend on the type of the substance, so no matter the size or amount of substance you have, the property does not change. For example, the color of copper does not change whether you have 2 g of it or 50 g.

An intensive property doesn't depend on the amount of substance where as an extensive property does depend on the amount of substance so yes an intensive property would be more useful to use because it won't change based on the amount of substance.
