Question

What is specific gravity? How is it related to density?

Answer 1

Specific gravity is defined as the ratio of the Densities of the two substances.

Specific gravity =
`\frac{\textup{Density of substance}}{\textup{1000}}`

Step-by-step explanation:

Specific gravity is defined as the ratio of the Densities of the two substances.

For the standardization, the density ration of densities is calculated with respect to the density of water i.e the denominator is the density of water.

Specific gravity =
`\frac{\textup{Density of substance}}{\textup{Density of water}}`

Also,

At STP density of water is 1000 Kg/m³

Therefore the relation between the specific gravity and density is,

The Specific gravity =
`\frac{\textup{Density of substance}}{\textup{Density of water at STP}}`

or

Specific gravity =
`\frac{\textup{Density of substance}}{\textup{1000}}`
