Helium lighter than air?

Published on

Density=mass÷volume Hence density is directly proportional to mass,so suppose you have taken a)1 litre of air and(b) 1 litre of Helium,You will find that weights.You will weigh them as air has other heavier molecules like Nitrogen ( Proton +neutron =14 amu) Where as Helium will be lighter as atomic mass (Proton+ neutron=4) Hence 4 is less than … Continue reading Helium lighter than air?
