Density

What?

Density is defined as mass per unit volume It is a fixed property for pure substances.Different materials usually have different densities, so density is an important concept regarding buoyancy, metal purity and packaging.

Formula:
? = m/v

where:

? (rho) is the density,
m is the mass,(in Kg)
V is the volume.(in m³)

The SI unit for density is:

* kilograms per cubic metre (kg/m³)
* grams per cubic centimetre (g/cm³)

Table of Densities

Water ………………………1.00 Glass………………………2.60
Granite……………………...2.650 Bone……………………….1.85
Human Body………………..0.995 Butter……………………...0.94
Ice…………………………...0.917 Carbon…………………….2.60
Kerosene……………………0.800 Chalk………………………2.36
Salt………………………….2.200 Coal………………………..1.50
Sand…………………………2.800 Cork………………………..0.25
Sulfuric Acid………………..1.840 Gasoline……………………0.72

Any object with a greter density than water, sinks in water
and also any object with a lesser density than water , floats in water.
