Helium is lighter than air (which means it can be used to make stuff float, like balloons) and a noble gas (which means that it won't react with other elements). Both of these qualities make helium very useful.
Helium gas does not expand significantly when heated due to its low molar mass and weak intermolecular forces. This property makes helium useful in applications that require precise control of volume and pressure.
Mostly hydrogen and helium.
No. Helium is an element, which makes it a pure substance.
yes it is resistant. helium does not react with anything.
element
Helium is lighter than air, which allows balloons filled with helium to float. Its low density also makes it safe for use in air-filled spaces.
How Helium is used: It is used to blow up balloons.
An unstable nucleus which decays emitting a neutron.
Helium gas does not expand significantly when heated due to its low molar mass and weak intermolecular forces. This property makes helium useful in applications that require precise control of volume and pressure.
Yes. Helium isn't flammable, which makes it the safer option.
Helium makes up about 0.0005% of the earth's atmosphere.
Helium is lighter than air. Hence balloons or blimps filled with helium will float.
A balloon filled with helium flies because helium weighs less than air.
no it has hydogen and helium but it makes heat and light
Helium makes up about 24% of the sun's mass.
Helium is an inert gas.
Helium!
