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.
Because it is inert, liquefied helium has a number of applications. It is used in cryogenics to freeze biological materials for long-term storage and later use (24%). It is also used in welding and to create controlled atmospheres. It is used to detect leaks in pipes. Its inert nature makes helium useful for cooling nuclear power plants. Since helium molecules are so small, mixtures of helium and have proven to be useful in treating people with severe asthma or lung problems. It is also mixed with oxygen for use in deep-sea diving. Most people are certainly familiar with the use of helium as a lighter-than-air substance. It holds up our birthday balloons. The motorized blimps that hover over sports stadiums are held up by helium. They are, in reality, very large balloons. see related link
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!
