Question

what do you mean by density​

Answer 1

Explanation:

The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume. ... Thus a relative density less than one means that the substance floats in water. The density of a material varies with temperature and pressure.

Answer 2

Answer:

Density is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water).
