Why hydrogen gas is liquefied first than helium gas?
Because hydrogen is lighter that helium
Is hydrogen more dangerous than oxygen Why?
Hydrogen is dangerous than Helium because Hydrogen is a stronger gas than Helium.
Why helium gas is used in weather balloons but not hydrogen?
Because helium (He) is lighter than air and not flammable like Hydrogen (H) which is the lightest element.
Why did the zeppelin company use hydrogen gas when helium gas would worked as well and been much safer?
During the time of the zeppelines, the US had more or less monopoly on Helium, and imposed an embargo on Germany on many things, one being Helium. The Hindenburg was designed for Helium, but had to turn to Hydrogen.
How does the density of helium compare with the density of hydrogen?
Helium is denser than hydrogen because as the molecular or atomic mass of a gas increases, density increases as well. Hydrogen has a molecular gas of about 2 g/mol while helium has an atomic mass of about 4 g/mol.
Is hydrogen or helium safer to use?
Generally speaking, helium is safer, as it is an inert gas, but Hydrogen is cheaper to make and is lighter.
Which floatation gas has been replaced by safer helium in airships?
The gas that helium replaced was Hydrogen

Which gas is lighter than helium?
hydrogen
Both hydrogen gas and helium gas are lighter than air. Why is helium used to lift blimps instead of hydrogen?
Hydrogen is higly explosive ! Remember the Hindenburg disaster.

Is an inert gas and has one more proton than hydrogen?
Helium
What are the gases found in the sun?
helium and hydrogen...
What gases are heavier than helium?
Helium exists as a monatomic gas, with atomic mass of 4.0. Thus any gas with a molecular mass higher than 4.0 would be heavier than helium. Hydrogen is the only gas that is lighter than helium; all others are heavier than helium.
