Density Definition in Science


In a liquid, the highest density liquid is at the bottom of the container.

In a liquid, the highest density liquid is at the bottom of the container.

DENSITY DEFINITION

Density is defined as mass per unit volume. The symbol most commonly used for density is ρ (the lower case Greek letter rho). The capital letter D is also used. Density is an intensive property of matter, which means the size of a sample does not affect its value. Density commonly is expressed in units of grams per milliliter and kilograms per liter.

The equation for density is:

density = mass / volume

ρ = m/V

The reciprocal of density (V/m) is its specific volume.

DENSITY EXAMPLE

Density tends to be higher for solids than for liquids, which are in turn more dense than gases. The density of pure water is defined to be 1 gram per milliliter.
