Relative Density - Measurements and Definition

The density of a substance can be defined as the mass of a substance per unit volume i.e. Density = Mass of substance/Volume of substance, It is one of the basic physical properties of a substance that can be used along with its other unique properties to characterize it and every substance has a different density Its unit is kg/m 3.Relative density on the other hand can be defined as the ...

The Density of Common Rocks and Minerals

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. This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).

The apparent density of coal briquettes is so high that theoretically it is possible to obtain a high-strength coke from semisoft coking coals if their density is kept high during carbonization. Moreover, the productivity in a conventional slot-type coke oven is controlled by heat conduction through the coal and the coke layer with a width of ...
