Air is 78,084 % nitrogen.
Hydrogen gas makes the ballon lighter than air therefore it drifts upwards
it is not gas it is just air
Yes. Burning hydrogen gas in air produces water vapor.
The old name of hydrogen gas is "inflammable air."
The air content of free hydrogen is far too small for air to be flammable by itself.

One common method to test for the presence of hydrogen gas is the "pop test." Collect a sample of the gas in a container, then introduce a flame. If hydrogen is present, it will burn with a pop sound. Another method is to use a colorless, odorless gas detector that can detect hydrogen gas in the air.
Zeppelins used hydrogen gas as the lifting gas to make them buoyant in the air.
When testing for hydrogen, a pop sound may be created. This occurs when hydrogen gas comes into contact with oxygen in the air and ignites, resulting in an audible pop. This is a common test for the presence of hydrogen gas.
hydrogen
Yes. Hydrogen is a gas, and all gases tend to diffuse. Whether or not air is present is irrelevant.
Hydrogen is the lightest gas found in air.
