Density is a physical property and not a chemical property because  density changes with respect to change in the states of matter. In  Solid, Liquid and Gas respectively, t â¦ he density changes. For  example, water, ice and water vapour have different densities.
The density of a given substance is constant, given constant conditions, regardless of the amount. Mass, on the other hand, is dependent on amount, as it is meaningless to try to define the mass of a substance without defining its volume and its environmental conditions. Mass and density vary greatly between various elements and their compounds.
