Question

what is dencity? give some example

Answer 1

Density is a characteristic property of a substance.The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume).The mass of atoms, their size, and how they are arranged determine the density of a substance.Density equals the mass of the substance divided by its volume; D = m/v.Objects with the same volume but different mass have different densities.

Answer 2

Density is a measure of mass per unit of volume. The average density of an object equals it's two total mass divided by its total volume.
Example:- Helium balloons.
Icebergs.
