the one I did was not difficult at all
Hydrometer measure the density of liquids.
The hydroscope (also called the hydrometer) is thought to be invented by Hypatia of Alexandria. If this is true, the first hydroscope was invented in the 4th century.
it is liquid
A hydrometer can be used to find the specific gravity (relative density) of a liquid by determining how much water it will displace. Various calibrations are used for different kinds of liquids.
a Hydrometer is used to measure the density of a solution, by the use of a scaled float. typically it is used for battery acid.
A hydrometer consists of a cylindrical stem and a bulb weighted with mercury or lead shot to make it float upright. Mercury has a higher density, thus a lower volume for the same weight than lead. It is a toxic liquid metal, but also more dangerous and difficult to clear up the mess when a glass hydrometer is broken
Hydrometer measure the density of liquids.
It measured by the density of the size from the hydrometer.
Salinometer
The hydroscope (also called the hydrometer) is thought to be invented by Hypatia of Alexandria. If this is true, the first hydroscope was invented in the 4th century.
Mrs.Tuft used a hydrometer to determine the specific gravity of a liquid
A hydrometer is used to find the specific gravity (or relative density) of liquids.
a hydrometer checks the state of battery charge using specific gravity.
a mathimatical term called a unit of hydrometer is what the study of gravity and other measurements
Hydrometer
it is liquid
hydrometer s used to check the acid in a dog's body
