Exploring Density Simulation Exploration: Login to the PHET Website. A basic property of any homogeneous substance is its density: the ratio of its mass to its volume. The density of a liquid or solid is an intensive property‚ which means that the density does not vary with the size of the sample but only depends upon its composition. The determination of density is a nondestructive physical process for distinguishing one substance from another. The mathematical relationship is: Density= massvolume
