Expert Answer
Density of an object is defined as the mass per unit volume of that object.
It is given as
where V is the volume of an object, and M is its mass.
It is a physical property of matter and measures the compactness of matter, of how much mass occupies a given space.
An object sinks or floats on water depending on its lightness or heaviness as compared to water.
Density of an object < water; object floats
Density of an object > water; object sinks
An object which has greater mass is called a heavy object, and an object which has less mass is called a light object.
