Extensive and Intensive

Postby Matthew Oh 3I » Thu Jan 28, 2016 4:36 pm

I'm still a little confused as to what extensive and intensive properties are and how to distinguish them

Lets say you have a sample of something.

An extensive property is one in which if you change the size of your sample, the property will also change. For example, volume, mass, and length are all extensive properties.

An intensive property is one in which if you change the size of your sample, the property will NOT change. For example, temperature, color, melting point, boiling point, molecular weight, and density are all intensive properties.

Hope that helps! :)

Also, if you wanted examples from what we're learning right now, enthalpy, entropy, and Gibbs free energy are extensive, while standard reduction potentials are intensive

Pertaining to today's lesson, an extensive property directly involves how much of a something is presented in a reaction, while with an intensive property, the amount present in essentially irrelevant to the concluding calculations.

To help distinguish the two it is helpful to think of possible properties and categorize them ..
Some examples of extensive properties are: volume, mass, size, weight, length
intensive properties include: boiling point, density, state of matter, color
