What happens when helium is heated up?

Answer 1

If the helium is confined to a fixed volume, the pressure will increase. If the volume is not constrained, the volume will increase. Because helium is such a small atom, it tends to diffuse through the walls of any container enclosing it. Increasing the temperature will also increase the rate of this diffusion since the atoms will be more energetic.

Answer 2

There is a certain mixture of helium and oxygen that has been used in Scuba tanks for divers that are going to be very deep for prolonged periods (say, 200 feet down for 25 minutes). It helps to prevent bends upon decompression.

There is no chemical reaction between these two elements.

Answer 3

Well, that depends upon the amount of heat energy in question. Nuclear fusion happens at sufficiently high temperature and pressure. Otherwise, you just have hot helium. Like all gas, helium will expand when heated, or in a sealed container, the pressure will increase. With enough heat you can make the sealed container explode.

Answer 4

Nothing, for Helium won't react with Element being added.

Its a noble gas.

Answer 5

Helium and hydrogen are gases completely miscible without any reaction.

Answer 6

Helium and hydrogen don't react; they form a completely miscible gas mixture.

Answer 7

It expandes and becomes hot, at some point it comes to a new agregatic state called plasma

Answer 8

At room temperature nothing; at high temperature thulium hydide (TmH2) is obtained.

Answer 9

The volume of the gas increase.
