Extensive v Intensive

Postby Dianna Grigorian 1C » Fri Feb 03, 2017 4:26 pm

I understand that the difference between extensive and intensive properties is that extensive depends on the amount of material, while intensive does not. But, why does that make intensive properties more useful?

Intensive properties can be considered more useful in Chemical Applications because they are particularly helpful in the identification of chemical substances since they are not dependent on the amount of matter present in a system (as extensive properties are). For example, think of a colorful ruby. A ruby will still appear to be red whether it is the size of pencil eraser or the size of a fist.

Hope that helps :)

Since intensive properties do not depend on the amount of substance, the entire system can be described with two independent intensive variables. Intensive properties can also be useful in identifying chemical substances because intensive properties do not change as the quantity of the substance changes.
