The Helium gas will expand and rise into the suurounding the air as it is less dense and lighter air. Depending on the amount of helium and the size of the room the Helium could displace the breathable mix in the space and become a danger to health.
the lighted splint would stop burning as Helium does not burn.
If the lid is removed from a container holding helium gas, the helium will escape into the surrounding environment since helium is lighter than air. This can result in the helium dispersing quickly due to its low density compared to the air around it.
The bottle will just feel like a bottle full of air. In order for it to float like a balloon filled with helium, it would have to weigh less than air or you would need to fill the bottle to well over its capacity. 1 cubic meter of helium is required to lift 1kg.
If one electron has been removed from Helium's electron shell then it is a He+ ion. If both of its electrons have been removed it becomes a He2+ ion. Either way they are both positive ions.
If you removed energy from neon gas, there would be a decrease in motion and more attraction between the particles.
If the lid of a jar containing helium gas is removed, the helium gas will quickly diffuse out of the jar and into the surrounding environment because helium gas is lighter than air. Helium is also non-toxic and non-flammable, so it will not pose any immediate danger.
It will escape
we would die

Helium is an inert gas and would smother a candle.
If temperature and volume is fixed,pressure reduces.
helium (He)
The abbreviation for gas helium is He.
