Density is a measure of how tightly the matter within it is packed together.
Hydrometer is used in batteries to measure density. A float tells you the density using displacement.
The three equations commonly used to solve density problems are: Density = mass/volume Mass = density x volume Volume = mass/density
Density is a measure of how much mass is contained in a given volume of a substance, while relative density is the ratio of the density of a substance to the density of a standard substance (usually water). Relative density is a dimensionless quantity used for comparison purposes.
Density is used to determine if a material will float or sink in a liquid by comparing the density of the material to the density of the liquid. If the material has a greater density than the liquid, it will sink. If the material has a lower density than the liquid, it will float. Objects float when they displace an amount of liquid equal to their own weight.
In lower classes viz sixth standard, the first letter of the word "density" ie 'd' is used. But later in higher studies instead 'd', 'rho' the greek letter is used as the symbol for density.

The density of water is 1.
Graphing is used in measuring density. It plots the temperature and density as read, and gives the true density at standard conditions.
density = mass/volume
100 DENSITY thats it..
Density or, more strictly, variations in density are perhaps most commonly used to separate materials of different density in a machine called a centrifuge. Density measures a relationship between the mass and volume of an object.
Density can be used to determine the mass and the volume of a given solid.
mega
density = mass/volume
density=mass/volume
density=mass/volume
Density can be used to identify a material by how much you get as an 'answer'. because if it is the same material then probably the density value will be similar. -By Anna 6-4
