Densities of liquids
Liquids have different densities.
Density of liquids is measured by an instrument called a hy-
drometer.
The hydrometer makes use of Archimedes' principle: a solid
suspended in a fluid is buoyed by a force equal to the weight of
the fluid displaced by the submerged part of the suspended
solid.
