That the material's density is less than the density of water.
density's younger brother
Density: the ratio mass/volume for a material, expressed in kg/m3 (SI). Relative density: the ratio between the density of a material and the density of pure water at the same temperature.
If your experiment shows that your unknown material has twice the density of your known material, you can simply look up the density of the control material and double it (or multiply by whatever the ratio is). This will give you the density of the unknown and you can attempt to identify it by looking for this number in a density table.
If we know the material that makes up the object, we will also know the density of the material. By measuring the volume and mass of the object, it is possible to find out if it is solid or hollow. This will only work if we know the material and we know the density of the material.
WHAT IS THE DENSITY OF CRCA WHAT IS THE DENSITY OF CRCA
CRCA - Cold Rolled Close Annealed Sheet Steel.
CRCA Sheet is ferrous, it is a steel.
cold rolled close annealed -CRCA
CRCA means "cold rolled close annealed".
Pressed steel radiator material specication is is 513 grade d of crca sheet

That the material's density is less than the density of water.
The density of material is expressed as volume divided by mass.
The density of a material is generally typical of a material. The density is it's mass divided by it's volume. So if you have something that weight 20kg and has a volume of 2500cm3 or 2.5L it's density will be 8gcm-3
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
