Density is how much matter is packed into a certain substance. So it's a measure of how tightly packed particles are. If particles are tightly packed, they will be more dense and if they're loosely packed they will be less dense. Normally, something solid will be more dense than something liquid. So density is how much matter there is a certain amount of space or volume.
