When dry, sand has a bulk density of about 80 to 100 pounds per cubic foot, while when damp, it is about 100. The bulk density of sand varies according to its texture.
Know MoreBulk density is a property of all particulate matter. It is calculated by dividing the mass of a substance by its volume. A material's bulk density may change depending on its handling. Powder in a cylinder has a different bulk density if the cylinder is disturbed. This is because the particles move, then settle more closely together, resulting in a different volume. Soil's bulk density varies according to its degree of compaction and its mineral makeup.
Learn more about PhysicsThe density triangle, sometimes called the mass-volume-density triangle, is a graphic aid that is intended to make calculations of any of the three variables easy once the other two are known. To use the density triangle, one variable, representing the value to be calculated, must be covered. This gives the relationship between the other two variables and serves as a reminder of the operation that determines the unknown value.
Full Answer >The formula for calculating density is mass divided by volume (density = mass/volume). Density is a measure of how much mass an object has per a given volume. Volume refers to the amount of three-dimensional space occupied by an object.
Full Answer >The formula to find an object's density is its mass divided by volume. Density is not possible to directly measure. To find the density of an object, it is necessary to find its mass and volume.
Full Answer >Density of any object is calculated by dividing the object's mass by its volume. Density is determined by the concentration of molecules in an object, so objects with a heavy mass in relation to a smaller volume have a higher density than objects with a lower concentration of molecules over a relatively large volume.
