Intensive and Extensive Properties

Some properties of matter change when the size of the sample changes. These are extensive properties—properties that change as the size of the sample changes. Examples of extensive properties are mass, volume, length, and total charge.

Other properties are the same for a substance, no matter the size of the sample—these are intensive properties. An intensive property doesn't change when you take away some of the sample. Examples are temperature, color, hardness, melting point, boiling point, pressure, molecular weight, and density.
