"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 (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.
For a liquid, we find that the speed of sound decreaseswith increasing density but increases with increasing bulk modulus. Increasing the dissolved solids will increase density, but also bulk modulus. In general, bulk modulus will increase "faster" with an increase in dissolved solids than density will increase. And this translates into a net increase in the speed of sound in water with increasing dissolved solids. Tap water has dissolved solids, so the speed of sound in tap water should be higher than it is in pure water at the same temperature and pressure.
Bulk density is defined as the weight per unit volume of material. Bulk density is primarily used for powders or pellets. The test can provide a gross measure of particle size and dispersion which can affect material flow consistency and reflect packaging quantity. Bulk Density ASTM D 1895 B

Tapped density is the term used to describe the bulk density of a powder (or granular solid) after consolidation/compression prescribed in terms of "tapping" the container of powder a measured number of times, usually from a predetermined height. The method of "tapping" is best described as "lifting and dropping". Tapping in this context is not to be confused with tamping, sideways hitting or vibration.
A value for porosity can alternatively be calculated from the bulk density ρbulk and particle density ρparticle: Normal particle density is assumed to be approximately 2.65 g/cm3, although a better estimation can be obtained by examining the lithology of the particles.

Bulk density = dry weight / volume, then by knowing the dry weight and bulk density we can calculate the volume.
bulk density depend on that material from which soil formed. so maximum bulk density depend on particle density of that mineral. Therefore,we can only tapped the soil upto perticle density. so maximum bulk density may be occur at equal to paricle density.
The density of an asteroid differs.
There are many types density, like true density, tap density, bulk density etc. Can use analyzer like G-DenPyc 2900 gas pycnometer analyzer to measure them. Aerometer or Hydrometer for density of liquids, Dasymeter for density of gases and Resonant Frequency and Damping Analyser (RFDA) for density of solids.

Definitely, soil texture influences soil bulk density
Bulk density is the dry mass of the solids (M sub t) / total volume (V sub t) Particle density is bulk density (P sub b) / 1 minus total porosity (1-theta).
I believe that it may be the same (or similar) to bulk density
Bulk density of coking coal depends on many factors. But commonly it can be told as 0.8 T/Cu.M.
