Question

what is relative density?​

Answer 1

Answer:

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. ... For example, an ice cube, with a relative density of about 0.91, will float. A substance with a relative density greater than 1 will sink.

Answer 2

Relative density

• Relative density, also known as specific gravity, has been the ratio of a substance's density (mass per unit of volume) to a density of certain reference data.
• Specific gravity is commonly used to refer to relative density in relation to water.
• So the density of materials changes with temperature and pressure, exact pressure and temperature where the density, as well as mass, need to be determined.

• $Relative density =\frac{Density ofbody}{Density of water}$
