The difference between the specific gravity and density is that at room temperature and pressure is 1gram per 1 cubic cm is the density of water this density is treated as a standard and the density of any other material (usual liquids) is calculated relative to this is called relative density or specific gravity. Relative density can also be defined as the ratio between the mass of the substance and the mass of an equal volume of water at 4°C. • Relative density = Density of a substance/Density of water → It has no unit as it is a ratio. Density in kg m 3 = R.D x 1000. The ratio of the density of a substance to that of the density of water is called relative density. out Class 9 lecture & lessons summary in the same course for Class 9 Syllabus. We know that a solid exerts pressure on a surface due to its weight. Relative density is a ratio so it has no unit. Relative density = Mass of an equal volume of water Mass of the substance As the relative density is the ratio of two similar quantities, it has no units. Students will classify matter based on physical properties, including mass, magnetism, physical state (solid, liquid, and gas), relative density (sinking and floating), solubility in water, and the ability to conduct or insulate thermal energy … 5.
