Question

hydrometer is used to determine select one: a. specific gravity of liquids b. specific gravity of solids c. specific gravity of gases d. density. e. relative humidity

Answer 1

A hydrometer is an instrument used to measure the specific gravity (or relative density) of liquids; that is, the ratio of the density of the liquid to the density of water. A hydrometer is usually made of glass and consists of a cylindrical stem and a bulb weighted with mercury or lead shot to make it float upright
