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.
Density is a component of mass and volume, it is the mass per unit volume.

A lay definition of density would be that it is how compact substance is packed together.
