No. Date Physics. "Density and Relative Density". Density of a subtance Is defined as the rate of its Masse to its Volume Donsity ofa liquid 2 Mass Volume Density of Water 2 1g /cm's or 10"kg/M3 In Case of hormogreous (isotropic) Subtance ithas no directional Relative Density. * Density of Subtance Density of Water at 4°C. = Weight of Subtance In Air loss of weight inwater. Relative density of a Subtance Is defined as the Ratio of its density to the density of Water at 9°C. Relative density also knows a specific Gravity has no Unit no dimensions For a solid body, Sasyty of obody = density of sub face
