Specific Gravity
Specific gravity.
This ratio is called the specific gravity.
Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water.
DENSITY : density is the ratio of mass and volume of the substance density=mass/volume RELATIVE DENSITY : It is the ratio of density of a substance to the density of water
DENSITY : density is the ratio of mass and volume of the substance density=mass/volume RELATIVE DENSITY : It is the ratio of density of a substance to the density of water
Density is a derived unit: mass divided by volume.
Specific gravity is otherwise known to be "Relative Density". It is the ratio of the density of a substance to that of water as water has been taken as standard. So though volume gets changed there is no chance to get change in the relative density as it is the characteristic property of the substance.
Density is mass per unit volume of a substance. The Mass and volume of water is in the ratio of 1:1 .There fore the density of water is 1. With rise and decrease of temperature the volume increases or decreases to change the water density.
its density. note. density is often expressed as the ratio of the density of the substance to the density of water at standard temperature and pressure. This is known as the specific gravity of the substance. It is a dimensionless number so it has no units.
Millilitres are units of volume and grams are units of mass or weight. They cannot be converted into each other.
Submerse the object in a completely full bucket. measure the volume of the displaced water due to the object. Multiply the volume of the displaced water by the density of the object to give mass.
