Specific gravity is a measure of how dense a substance is compared to the density of water. It is expressed as a unitless ratio and is used to compare the density of different materials.
according to Geology.com the specific gravity of Chalcopyrite's is 4.1 -4.3.
The specific gravity of a diamond typically ranges from 3.5 to 3.53. This means that a diamond is approximately 3.5 times denser than water.
The specific gravity of jade varies depending on the type and quality. On average, jade has a specific gravity ranging from 2.9 to 3.3. Finer quality jades typically have a higher specific gravity due to their density and composition.
The specific gravity of flint ranges from 2.2 to 2.6.
Hydrogen monoxide.
Specific gravity is a measure of how dense a substance is compared to the density of water. It is expressed as a unitless ratio and is used to compare the density of different materials.
The volume is the ratio mass/density.V = 0,45359237 / 1,1295 = 0,4 litre
Hydrogen, helium and oxygen are gases. Gravity is a physical property of any substance.
Aluminum has no specific gravity, at least by the current definition of gravity.
The specific gravity of acetone is approximately 0.79 at 20°C.
mica has the specific gravity of 2.88
Specific gravity of ppc is 3.15
Gravity affects hydrogen the same way it does any other element. Hydrogen is lighter than air (nitrogen and oxygen) and therefor is buoyant in air, meaning it floats. No more differently than a piece of wood floats on water. There is no force counteracting gravity's force on the hydrogen, except that nitrogen and oxygen are pulled down to earth displacing the hydrogen. when the hydrogen reaches the outer layer of the atmosphere it will be held there by gravity until some other force (solar wind maybe) strips it away from the earth.
