The English phrase 'specific gravity' means the ratio of
the density of a substance to the density of water.
Aluminum has no specific gravity, at least by the current definition of gravity.
An instrument for measuring the specific gravity of fluids; a form hydrometer.
Specific gravity of a mineral is a measure of its density compared to the density of water. It is a dimensionless ratio and is used to identify and classify minerals based on their weight. Minerals with a specific gravity greater than 1 are denser than water, while those with a value less than 1 are less dense than water.
mica has the specific gravity of 2.88
Specific gravity of ppc is 3.15
The specific gravity of acetone is approximately 0.79 at 20°C.
Specific Gravity.
The specific gravity of quartz is nearly 2.65.
I just learned about this in chem11. I'll give the definition off my sheet. Specific gravity is a dimensionless unit defined as the ratio of density of a material to the density of water at a given temperature (usually at 4oC). Note that this expression is obsolete today; use the density.
Relative density, is also called specific gravity, and it is the ratio of the density (mass/volume) of a substance to the density of a particular reference substance, usually water. So, where density has the units of mass/volume, relative density (specific gravity) is unitless.
according to Geology.com the specific gravity of Chalcopyrite's is 4.1 -4.3.
Diamond has the specific gravity of 3.5, which is above average.
