For example, the density of a one-inch cube of iron is much greater than the density of a one-inch cube of cotton. In most cases, denser objects are also heavier. The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water.
Therefore, the specific gravity of gold is simply 19.3. Anything with a density greater than 1,000 sinks in pure water at 4 degrees Celsius, and anything with a density less than 1,000 floats. As youd expect, gold, with a density of 19,300 kg/m 3, sinks. Ice, on the other hand, with a density of 917 kg/m 3, floats.
2 Density itself is a factor of at least several things when it comes to gems and minerals. 1) chemical composition (atomic mass), 2) chemical bonding or packing, 3) Mixed density due to more than one substance combined or nonuniform mixing, 4) temperature of the substance.
With the above chart the per cent solids or specific gravity of a pulp can be determined for ores where gravities do not coincide with those in the Pulp Density Tables. This chart can also be used for determining the specific gravity of solids, specific gravity of pulps, or the per cent solids in pulp if any two of the three are known.
(Standard Test Method for Density, Relative Density (Specific Gravity), and Absorption of Coarse Aggregate). Testing revealed that ASTM C127-07 does not accurately represent the particle density of the material due to the large surface pores where, mainly in the blast slag samples.
Weight is a force, and is affected by gravity. An object would weigh less on the moon than on the Earth, because there is less gravity there. Mass stays the same wherever you are: the earth, the moon, or floating in outer space! For simple density experiments, you can use scales to
Again, the specific gravity is the density of the substance divided by the density of water, so This shows that the specific gravity does not change when measurements are made in different units, so long as the density of the object and the density of water are in the same units.

Specific gravity is the heaviness of a substance compared to that of water, and it is expressed without units. In the metric system specific gravity is the same as in the English system. If something is 7.85 times as heavy as an equal volume of water (such as iron is) its specific gravity is 7.85.
Density is the mass of material per unit volume. Specific gravity is a ratio of the mass of a material to the mass of an equal volume of water at 4 o C. Because specific gravity is a ratio, it is a unitless quantity.

1 DENSITY and SPECIFIC GRAVITY Most students have felt how heavy normal rocks and minerals are. But many have never handled especially light minerals such as borax, or very heavy ones, such as a nugget of pure gold.
To calculate the specific gravity (SG) of an object, you compare the object's density to the density of water: Because the density of water in g/cm 3 is 1.0, the SG of an object is will be almost the same as its density in g/cm 3. However, specific gravity is a unitless number, and is the same in the metric system or any other measurement system.
