How many gases are lighter than air
Web4 jun. 2024 · Light elements Some substances, like helium and hydrogen, are lighter than air. These gases rise into the atmosphere, yet this does not mean that they disappear into space when you puncture a helium balloon, for example. WebIt would definitely rise, but barely. Also comparing nitrogen's density to ethylene's is pretty pointless, only the ethylene/air comparison really matters. 3. ct450 • 5 yr. ago. Thanks for the quick answer. I don't know much about chemistry, so when you barely do you mean it will rise slowly or it will rise to a certain point.
