The density of these fish varies from 3 to 25 individuals per square metre.

On the other hand, the density varies in a different way.

The density varies from 0.94 to 0.96 mg/l, with the higher values forming the more rigid products.

The density of a material varies with temperature and pressure.

If the body is not homogeneous, then its density varies between different regions of the object.

The density of the plantations varies from 500 to 3300 plants per hectare.

If the density of the fluid varies with height, mathematical integration would be required.

Strangely, the density of the Moon hardly varied across its whole interior.

This will occur in any system wherein the density of the moving fluid varies with position.

In protected areas, the density of animals varies between 5/km2 and 16/km2.
