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. Density is the mass per unit volume. This means that the density of any solid, liquid or gas can be found by dividing its mass in kilograms by its volume in cubic metres. Density can be found using the equation: 1  The unit for density is kg m -3. 2  The density of water is approximately 1000 kg m -3 and air is approximately 1.3 kg m -3.his means that the density of any solid, liquid or gas can be found by dividing its mass in kilograms by its volume in cubic metres.
