## What is a meaning of relative density?

relative density. noun. the ratio of the density of a substance to the density of a standard substance under specified conditions. For liquids and solids the standard is usually water at 4°C or some other specified temperature.

What is density and relative density?

Density of a substance is defined as the mass per unit volume of the substance. Relative density : Relative density of a substance is the ratio of its density to that of water.

### What is relative density physics class 9?

The relative density of a substance is the ratio of its density to that of water. Relative density is a ratio so it has no unit.

What is density in simple words?

Density is defined as how tightly or loosely packed a substance is, or to the number of things or people in a certain area. A measure of the quantity of some physical property (usually mass) per unit length, area, or volume (usually volume). &diamf3 Mass density is a measure of the mass of a substance per unit volume.

## What is relative density write its formula?

And Relative density is ratio of density of substance to that of water i.e. Relative density = DensityofwaterDensityofsubstance​

What are the applications of relative density?

Uses of relative density – definition

• It is used for determining the density of unknown substance from the known density of another substance.
• It is used by geologist to find out the mineral content into the rock.
• Testing purity of a substance (example gold).

### What is relative density example?

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.

What is relative density in physics class 8?

Generally, the relative density is the density of an object relative to the density of water which has a value of 1g/cc; where g= gram; cc= cubic centimeter. There is one other coined term known as specific gravity. Specific gravity is another word for relative density. Specific gravity is a ratio.

## What is relative density in science for kids?

Relative density is a ratio of the densities of two materials. The term specific gravity is similar but not same. In specific gravity, the reference material is water. If a substance’s relative density is less than one then it is less dense than the reference; if greater than 1 then it is denser than the reference.
