What can helium be used for?

Answer 1

It is lighter than air so it is used in balloons and airships (as a gas) to make them float and as a coolant (as a liquid). And also when you suck helium your voice changes and goes really high pitched and squeaky (your voice changes back to normal almost staight away).

Answer 2

filling party balloons as it is a much safer gas (non-flammable)

widely used as an inert gas shield for arc welding

high speed push gas inside air to air missiles for guidence corrections.

protective gas in growing silicon and germanium crystals, and in titanium and zirconium production

cooling medium for nuclear reactors, helium won't become radioactive

a mixture of 80% helium and 20% oxygen is used as an artificial atmosphere for divers and others working under pressure

cryogenics and superconductivity

rare document preservation (i.e. Declaration of Independence)

as a gas for supersonic wind tunnels

pressurizing agent for liquid fuel rockets (inert so won't react)

leak detection agent for extremely small leaks.

nuclear detonation simulations (using conventional explosives)

isotopic dating by helium ratios (seawater, ocean beds,etc)

helium/neon lasers

helium cardio-pulmonary resusitation pump (heart surgery)

helium filled border patrol "AEROSTAT" monitoring blimps

Answer 3

Some of the uses of helium are:

1. It is used for filling balloons and airships as it is light and non combustible.

2. It is used in producing inert atmosphere in metallurgical operations and welding of metal.

3. A mixture of helium and oxygen is used for respiration in deep sea diving.

4. It is used to produce and sustain powerful super-conducting magnets which are used in NMR and MRI technologies.

5. It is used in gas cooled nuclear reactor.

6. Liquid helium is used as cryogenic agent.

Answer 4

The greatest single use of helium is in cryogenics. This is because helium, when liquified, is one of the coldest substances known to man, boiling at 4 Kelvin (-452 degrees Fahrenheit.) It is commonly used in magnets used for MRIs and nuclear magnetic resonance spectroscopy. (These magnets are made with superconducting wires that allow electric current to circulate forever without any resistive losses as long as they are kept cold enough.) The Tevatron, a particle accelerator at Fermilab in Batavia, Illinois, uses 400,000 liters of each year for its magnets. Liquid helium finds other uses any time someone needs extremely cold temperatures - whether as part of scientific research or material creation.

A second category of usage is in rockets and balloons - and not just the ones you buy for Valentine's Day. NASA uses large helium filled balloons to take objects almost into space to study atmospheric composition and to make observations of space that the atmosphere makes difficult. In rockets, it is used for pressurizing liquid fuels.

Answer 5

in a store of corse in the balloon section a fair anywhere where balloons are sold.

Answer 6

Helium is used for many different things such as making balloons float to making your voice squeaky. I prefer making your voice squeaky because it's fun.

Answer 7

helium can be used for blowing balloons
