41:4.2 Gaseous, liquid, and solid states are matters of atomic-molecular relationships, but density is a relationship of space and mass. Density varies directly with the quantity of mass in space and inversely with the amount of space in mass, the space between the central cores of matter and the particles which whirl around these centers as well as the space within such material particles. | 41:4.2 Gaseous, liquid, and solid states are matters of atomic-molecular relationships, but density is a relationship of space and mass.
