The reference density of water at 4 oC (39 oF) is used as the reference as these are the conditions of maximum density. Where SG = specific gravity, ρ = density of the material (kg/m 3), ρW = density of water ( kg/m 3). The following formula is used to calculate the specific gravity of a material. The specific gravity of all other materials is compared to water as a fraction heavier lighter or heavier density. The specific gravities of gases usually are compared to dry air which generally has a density of 1.29 g per litre.

By definition, water has a density of 1 kg per litre at this temperature. In more general terms specific gravity is the ratio of the density of a material to that of any standard substance, although usually this is water at 4 degrees Celsius or 39.2 degrees Fahrenheit. Specific gravity is unique to every material and has a very wide range of application. The temperature and pressure of both the material and water need to be the same as these factors influence the density and hence the specific gravity. So it is possible that different amounts of water could have the same density.The Specific Gravity of liquids and solids is defined as a dimensionless unit which is the ratio of density of a material to the density of water at a given temperature, where density is defined as the material’s mass per unit volume and is measured in kg/m 3. The bucket with less mass has less volume. Students may point out that the bucket with more water has more mass but a greater volume.

Students make a graph of the relationship between the volume and the mass of water. Then they measure the mass of different volumes of water and discover that the density is always the same.

Students measure the volume and mass of water to determine its density.

The density of a substance is the same regardless of the size of the sample.The density of water is 1 gram per cubic centimeter.Just like a solid, the density of a liquid equals the mass of the liquid divided by its volume D = m/v.The mass and size of the molecules in a liquid and how closely they are packed together determine the density of the liquid.The molecules of different liquids have different size and mass.The volume of a liquid can be measured directly with a graduated cylinder.Just like solids, liquids also have their own characteristic density.
