Question
Even though cement and bread are not substances, they can help you to understand these
concepts:
Whatever you do to volume affects mass the same way.
Whatever you do to mass affects volume the same way.
If you have half as much of a material, you would expect the volume of the material to also be
half as much. If you have twice as much of the material, you would expect its volume to also be
twice as much. Substances, which you know are always the same throughout, will follow this
rule. This relationship between mass and volume will stay the same for any substance, no matter
how much of that substance you can sample and measure in the classroom.
Why is this principle about the relationship between mass and volume always true of
substances, but not always true of mixtures?
