Industrial chemistry Technical gases
Gas cylinders are used for storage and transportation of technical gases. It is known that hydrogen is the lightest gas. Why is a cylinder with hydrogen heavier than cylinders with other technical gases?
Probably due to the greater thickness of the metal. so that the gas does not diffuse and with high pressure
I'm not an expert in the field, but hydrogen is for sure a danger when it comes to detonation, so maybe metal for it storage is more heavy itself. But it doesn't seems right to assume that ability of metal to hold high pressure have a correlation with it's molar weight
@chaoticgood Metal has nothing to do with it, we are talking about technical gases.
@argentum An interesting assumption. Indeed, hydrogen has the highest diffusion rate, its molecules propagate faster than the molecules of all other gases in the medium of another substance.
@damiryagudin Due to the low density of hydrogen gas, hence the volume is larger.
You mean density of liquid hydrogen? In gaseous form hydrogen can be viewed as an ideal gas, therefore it's density isn't influenced by it's chemical nature
