Helium flammability

Helium (from Greek: ἥλιος, romanized: helios, lit. 'sun') is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas and the first in the noble gas group in the periodic table. Its boiling point is the lowest among all the elements, and it does not have a melting point at standard pressure. It is the second lightest and second most abundant element in the observable universe, after hydrogen.

Web9 aug. 2024 · At 0ºC and standard atmosphere, hydrogen has a density of 0.0899 kg/m3, while helium’s is 0.1785 kg/m3. Under the same conditions, air has a density of 1.293 kg/m3. This means that at sea level on a 0ºC day, hydrogen provides enough buoyancy to lift 1.2031 kg per cubic meter, while helium can only lift 1.1145 kg per cubic meter of gas.
