### Extensive/Intensive Property

What does being an intensive/extensive property mean?

### Re: Extensive/Intensive Property

Extensive properties depend of the amount of substance or matter measured while intensive properties, like boiling point and density, do not

### Re: Extensive/Intensive Property

To add to the above response, you can also consider heat capacity vs. specific heat capacity.

The heat capacity of a bomb calorimeter, for example, does not depend on the amount of substance because it is a defined object. It has a specified mass for which to measure it's heat capacity, and we cannot change that mass-- we do not consider it. Therefore, we measure the heat capacity of the calorimeter as a whole. This makes heat capacity an intensive property to the calorimeter.

On the other hand, specific heat capacity is measured in the units J/°C* g. As you can tell, it measures how many joules it will take to raise ONE GRAM of a substance by one degree celsius. Therefore, because specific heat capacity is dependent on the amount of a substance, it is an extensive property. We need to measure the amount of substance before we find specific heat.

Intensive properties do not depend on quantity while extensive do. Intensive are preferred because they are more standardized.

You can change an extensive property to intensive by dividing it by something like mass so that it is not "dependent" anymore
