Bulk density is a measure of how much mass is contained in a given volume of a material. It is calculated by dividing the mass of the material by its volume, typically expressed in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³). This property is important in various fields, including agriculture, geology, and material science, as it helps determine how compact a substance is. In practical terms, bulk density can influence the behavior of materials during processing and their performance in applications. For example, in soil science, understanding the bulk density of soil can help assess its health and ability to support plant growth. Similarly, in construction, knowing the bulk density of building materials can aid in structural design and stability.
