Question

Why do object like metals or stones sink in water?

Answer 1

1. Density is the mass per unit volume.
2. $Density=\frac{mass}{volume}$
3. An object that has a higher density than the liquid will sink.
4. An object that has a lower density than the liquid will float.
5. Objects like metals or stones sink in water due to the fact that the density of metal or stone is more than the density of water, and hence it sinks.
