Substances that are denser than water will sink while those that are less dense than water will float.
Density and floatation
The density of a substance is a measure of the mass of the substance relative to its volume.
Thus, the density of any substance is a measure of how heavy the substance is.
This means that any substance whose density is more than that of water is heavier than water and will, therefore, sink in water.
In the same vein, substances whose densities are lower than that of water are lighter than water and will float on it.
