AbstractThe calculation of the molecular column density from molecular spectral (rotational or ro-vibrational) transition measurements is one of the most basic quantities derived from molecular ...

Compressibility(C p): Compressibility is a calculation of a powder’s unit volume change after applying pressure. C p =100(ρ T −ρ B /ρ T) In this video, Shelly Zhang from Bettersize instrument teaches ...

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 ...
