they have the same color and shine. These, then, are intensive properties.
The ways that the two samples differ would be extensive properties. For ex-
ample, they would have different sizes and different masses. Mass and vol-
ume, which do depend on the size of the sample, are extensive properties.
Examples of Intensive and Extensive Properties
Intensive Properties
Density, freezing point, malleability,
ductility, electrical conductivity.
Extensive Properties
Mass, volume, weight, length.
Try the following practice questions and check your answers at the end
of the chapter before moving on to the next lesson.
