Helium: A byproduct of the natural gas industry Blimps, dirigibles, zeppelins, anti-aircraft balloons, weather balloons and other lighter-than-air craft have all used helium as a lifting gas. It is much safer than hydrogen because it is not flammable. This was the most important category of helium use until the end of World War II. Much lower amounts of helium are now used as a lifting gas.

Helium Helium is the second lightest element and is the second most abundant element in the observable universe, being present at about 24% of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined.iquid helium is used in cryogenics (its largest single use, absorbing about a quarter of production), particularly in the cooling of superconducting magnets, with the main commercial application being in MRI scanners.

Breathing gas Hydreliox is a mixture of oxygen, helium, and hydrogen and is used for dives below 130 metres in commercial diving. Hydrox, a gas mixture of hydrogen and oxygen, is used as a breathing gas in very deep diving. Neox (also called neonox) is a mixture of oxygen and neon sometimes employed in deep commercial diving.

What's up with helium for welding applications? In other areas of manufacturing, the goal may be simply to limit the use of helium. Lyttle pointed out the use of a CO2 laser for welding applications as an example. Traditionally, helium is used as a shielding gas in CO2 laser welding, but it is supplied in a less-than-efficient manner to the area.

Helium Helium's other industrial uses—as a pressurizing and purge gas, as a protective atmosphere for arc welding and in processes such as growing crystals to make silicon wafers—account for half of the gas produced. A well-known but minor use is as a lifting gas in balloons and airships.

Helium Helium is commercially available in either liquid or gaseous form. As a liquid, it can be supplied in small insulated containers called dewars which hold as much as 1,000 liters of helium, or in large ISO containers which have nominal capacities as large as 42 m 3 (around 11,000 U.S. gallons).

- Western Digital's new helium-filled hard drives prompted questions about whether it is wise to use already low helium reserves for this purpose. In reality, the helium supply is growing, and the drives would use a minuscule amount of it anyway. Here are 9 other ways that helium is used today.

In chess can the kinght jump over the enemies piece? Can the same color chess piece jump over each other? The Knight technically does not 'jump' but it appears to be able to 'jump' over pieces of its own color as well as pieces of its opponent's color. The other pieces of the … same color cannot jump over each other. Neither can the other pieces jump over an opponent's piece.

What Is a List of Gases Lighter Than Air? Party balloons are commonly filled with Helium. Hydrogen possesses significant lifting power, but is highly explosive. Methane, the primary component in natural gas, makes a good substitute for Helium and Hydrogen because it does not leak through balloons as quickly as the other two gases. Learn more about Chemistry

Helium Helium is a chemical element with symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas that heads the noble gas group in the periodic table. Its boiling and melting points are the lowest among all the elements.elium is the second lightest element and is the second most abundant element in the observable universe, being present at about 24% of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined.

Helium The use of helium reduces the distorting effects of temperature variations in the space between lenses in some telescopes, due to its extremely low index of refraction. This method is especially used in solar telescopes where a vacuum tight telescope tube would be too heavy. Helium is a commonly used carrier gas for gas chromatography. The age of rocks and minerals that contain uranium and thorium can be estimated by measuring the level of helium with a process known as helium dating. Helium at low temperatures is used in cryogenics, and in certain cryogenics applications. As examples of applications, liquid helium is used to cool certain metals to the extremely low temperatures required for superconductivity, such as in superconducting magnets for magnetic resonance imaging.

- Because it is very unreactive, helium is used to provide an inert protective atmosphere for making fibre optics and semiconductors, and for arc welding. Helium is also used to detect leaks, such as in car air-conditioning systems, and because it diffuses quickly it is used to inflate car airbags after impact.

Where is Helium Found Universe. Helium is the second lightest element in the known universe. It is also the second most abundant. According to some estimates helium accounts for as much as 24 percent of the Universe’s mass.This element is also plentiful since it is a prime product of fusion nuclear reactions involving hydrogen.ike mentioned before Helium is rare on Earth but there are places where it is readily found. If you look at space the majority of helium is in stars and the interstellar medium. This is due to the fusion reaction that powers most stars fusing single hydrogen atoms to create helium atoms.

Helium: the essentials Helium around us. Helium has no biological role. Helium is present in the atmosphere at about 0.0005% (1 part in 200000) by volume and is an important component within hydrocarbon gases in the USA. Its origin in these gases is traced to the decay of radioactive elements in rocks.

- Helium (atomic number 2, symbol He) is a non-toxic, tasteless, odorless, and colorless gas. Heading the noble group, it is an inert monoatomic gas, and its melting and boiling points are some of the lowest compared with other elements. Except in extreme conditions, helium exists as gas only.

- Pure helium is a medium that allows sound to pass through it more quickly than air, so it makes your voice sound higher pitched (the mechanics are similar to speeding up a video and hearing the sound pitch up). Some gases will do the opposite; most commonly, sulfur hexaflouride, which slows down sound waves.
