It is tempting to think that some materials are always heavier than other materials. For example, someone might say that metal is heavier than air. But it depends on how much of each material there is ...

Bulk Density(ρ B): Bulk density of a powder is the weight of loose powder sample in unit volume. ρ B =M/V In this video, Bettersize application engineer Shelly Zhang is measuring the bulk density of ...

Scientists have developed a way to measure the density of a single cell. The new method involves measuring the buoyant mass of each cell in two fluids of different densities. Measuring cell density ...

New laser measurement technology necessary for controlling extreme conditions inside future fusion power plants is under development at Tokamak Energy, a British fusion energy company. A new laser ...

Yes, the future of the world’s climate is tied to the ability of forests to absorb atmospheric carbon. But exactly how well they can do that job depends on the density of the forests themselves, and ...
