intensive vs extensive

Postby Sophia Dinh 1D » Sat Mar 14, 2020 6:39 pm

what is the difference between the two and why is it important to know the difference?

Extensive depends on the amount while intensive doesn't. It's important because it tells us which constant or which equation to use like specific heat capacity vs heat capacity, etc.

Extensive represents things that are dependent on amount. While intensive represents things that aren't dependent on amount, like density. It is important to consider these when using constants and equations during your calculations.

Extensive properties depend on the amount of substance, while intensive properties do not depend on the amount.

Extensive: mass dependent
intensive: mass independent
Determines what units or constants you use in equation

extensive property: property that depends on the amount of matter.
Ex: mass, volume, length, charge

Intensive Property: Does not depend on the amount of matter
Ex: melting/boiling point, pressure, density, concentration

Intensive properties are not effected by the amount of the substance. For example boiling point or molecular weight.

Extensive properties are effected by the amount of the substance. For example mass or volume of a gas.

intensive = doesnt depend on amount of matter; extensive = depends on amount of matter

ex. intensive --> specific heat capacity; extensive --> heat capacity
