## Rocks and Minerals Dictionary SPECIFIC GRAVITY

The specific gravity (abbreviated s.g.) of a material is a comparison of its weight with the weight of an equal volume of water. Specific gravity measures the density of a material. Substances with a low specific gravity (like cork, which has a s.g. of 0.24) are not very dense; substances with a

Recall that Specific Gravity is the ratio of the density of a substance to the density of water. The density of water varies less than 1.5 mg/cm 3 over the narrow range of normal temperatures. Between 20 o C and 25 o C the density of water is essentially 1 g/cm 3. The volume expansion of the solid mineral

Specific gravity is a dimensionless unit that defines the ratio between the density of a rock and the density of water at, typically, 4 Celsius. Density is an important characteristic of a rock, since this parameter helps to identify the rock type and its geologic structure.

A substance that has a specific gravity thats lower than 9.2 would float on top of the tube. A substance with a specific gravity that is greater than 9.2 but less than 1 would float between the oil and the water. A substance that is very dense, with a specific gravity that is higher than 1.3, would sink to

Again, the specific gravity is the density of the substance divided by the density of water, so This shows that the specific gravity does not change when measurements are made in different units, so long as the density of the object and the density of water are in the same units.

Read More## Specific Gravity and Bulk Density Mining SGS

Specific gravity is the density of a material relative to water. Since rocks are comprised of several distinct mineral phases, they do not have a fixed specific gravity. Instead, a rocks bulk density arises as a result of the percentage of all minerals in a sample multiplied by the specific gravity of each.

For example, the density of a one inch cube of iron is much greater than the density of a one inch cube of cotton. In most cases, denser objects are also heavier. The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water.
