3.5 Intensive And Extensive Properties - Quiz

Intensive and Extensive properties are different but confusing. The screencast will provide you with an easy way to distinguish between the two.


Properties can be classified as either intensive or extensive.



Extensive properties are those that depend on the amount of substance present. If there is more of the substance, the property changes, such as mass. The more of a substance you have, the more mass there is.



Intensive properties are those that are constant for any amount of substance. For example, density is the same with any Read moreamount of substance present. No matter how many grams you have, it will always have a proportional volume. The fraction will always simplify to the same number.
