Word of the Day- Density is the measure of how compact the mass is per volume. It is calculated as mass divided by volume. When solids are placed in a liquid, objects more dense than the liquid will sink and objects less dense will float. Liquids when mixed together will sort based on their densities, the most dense closest to the bottom and the least dense towards the top.
