"Tapping" is a procedure in which a powder is placed into a graduated cylinder which is then tapped to compress the sample before its volume is measured. This reduces the amount of air trapped in the material. "Theoretical" is a method of determining the density of a mineral from the volume of a single cell.

Tap density is the density of a powder when tapped or compacted to minimize void spaces, providing a measure of how closely packed the particles are. Bulk density, on the other hand, is the density of a powder in its loose, unpacked state and includes the void spaces between particles. In general, tap density is higher than bulk density due to the compaction of particles during tapping.
Tap density (or packed density) refers to the density a volume a specific weight of powder has after it has been settled or packed until nofurther volume change is observed.
Apparent (or bulk or Scott density) is the density of a weight of a certain volume of powder. The powder is allowed to flow freely and gently into a container of a known volume.
The difference is tap density is the density of a compacted powder and bulk density is the density of a powder with no compaction at all. Both methods use different apparatus but use the formula of density = mass/volume.
The bulk density of magnetite can be calculated using the formula: Bulk Density = (mass of material) / (volume of material). This formula involves measuring the mass of the magnetite sample and calculating its volume to determine the bulk density.
The speed of sound in tap water is slightly faster than the speed of sound in pure water. This is because tap water contains impurities and dissolved minerals that increase its density, leading to a faster speed of sound compared to pure water.
Bulk density and porosity have an inverse relationship. As bulk density increases, porosity decreases and vice versa. Bulk density is a measure of the mass of soil per unit volume, while porosity is a measure of the void spaces within the soil.
Tap density is a measure of the bulk density of a powder sample achieved by mechanically tapping or vibrating it to eliminate voids and achieve maximum packing efficiency. It is an important parameter used to assess the flow properties and compressibility of powders in various industries such as pharmaceuticals and food processing.
The bulk density of barite typically ranges from 2.8 to 4.3 grams per cubic centimeter (g/cm3).
