Bulk density, also called apparent density or volumetric density, is a property of powders, granules, and other "divided" solids, especially used in reference to mineral components (soil, gravel), chemical substances, (pharmaceutical) ingredients, foodstuff, or any other masses of corpuscular or particulate matter (particles). Bulk density is defined as the mass of the many particles of the material divided by the total volume they occupy. The total volume includes particle volume, inter-particle void volume, and internal pore volume. Bulk density is not an intrinsic property of a material; it can change depending on how the material is handled. For example, a powder poured into a cylinder will have a particular bulk density; if the cylinder is disturbed, the powder particles will move and usually settle closer together, resulting in a higher bulk density. For this reason, the bulk density of powders is usually reported both as "freely settled" (or "poured" density) and "tapped" density (where the tapped density refers to the bulk density of the powder after a specified compaction process, usually involving vibration of the container.) In contrast, particle density is an intrinsic property of the solid and does not include the volume for voids between particles. (Wikipedia).

Bulk Modulus of Elasticity and Compressibility - Fluid Mechanics - Physics Practice Problems
This physics video tutorial explains how to solve problems associated with the bulk modulus of materials. The bulk modulus is the ratio of bulk stress and bulk strain. The bulk stress is the ratio of force and area which is equivalent to the pressure exerted by a fluid. The bulk strain

Surface critical dynamics and Casimir forces in a binary fluid by Sutapa Roy
Confining a near-critical mixture in a narrow-slit gives rise to critical Casimir forces (CCF). While the static properties of these forces are reasonably well understood, studies on its dynamic counterpart are very new and rare. Upon quenching a fluid from the mixed, homogeneous phase to
