    Math Definitions -> D -> Density


A measure of how much matter is in a certain volume.

This gold bar is quite small but has a mass of 1 kilogram (about 2.2 pounds), so it contains more matter than a similar sized piece of wood.

So gold is more dense than wood.

The density of water is about 1 kg per liter (1 liter of water has a mass of 1 kg), so anything that floats has a lower density, and anything that sinks is more dense.
