In its natural state, it doesn’t have any smell, taste or color. Common Uses of Helium Evidence shows that the human voice can be changed with a bit of helium. The gas is also used as light weight aircraft While balloons are perhaps the best known use of helium, they are a minor part of all helium use. Helium is used for many purposes that require some of its unique properties, such as its low boiling point , low density , low solubility , high thermal conductivity , or inertness . 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.

Unfortunately, instead of obtained a laugh, sadness was appeared. She died because of the oxygen flow in the body displaced by helium. More terrible thing is that the fact that helium is dangerous caused some people who are desperate to use it as a suicide tools.

Important facts are: Helium is a non-inflammable and light gas next to hydrogen. Hence, it is used in filling balloons for meteorological observations. It is also used in gas-cooled nuclear reactors.

Helium facts and uses

Helium is also used as a heat-transfer medium in some gas-cooled nuclear reactors. Helium can be used to detect leaks in high-vacuum and high-pressure equipment. Helium can be used to detect leaks (small fractures) in some vessels. This is due to the fact that it diffuses through solid materials three times faster than air.

I thought I had lost thing thin, and when it turned up in my office I was overjoyed, it is one of my favorite gadgets, quite a marvel of miniaturization even if it is a hundred times bigger and a hundred times more expensive than the current model. Uses for Helium. Because of its extremely low boiling temperature—just four degrees above absolute zero—liquid helium is the standard coolant for superconducting magnets used in MRI (magnetic resonance imaging) devices and particle accelerators. Interesting Facts about Helium. The speed of sound in helium is around three times the speed of sound in the air. This causes people's voices to get high pitched and squeaky when they breathe helium (note: never breathe helium as you can suffocate if you breathe too much). Amazing Helium Facts It is the second most abundant element in the universe and is also the second lightest, following behind hydrogen in both cases.

The helium mass spectrometer was also vital in the atomic bomb Manhattan Project. Helium is used four different ways in the semiconductor manufacturing process: in a specialized cooling process, as a dilutant gas for plasma etching, as a carrier gas for deposition processes, and as a leak detector. All modern electronics, including video games, televisions, and even solar panels rely on semiconductors and therefore, helium. Helium can be used to detect leaks in high-vacuum and high-pressure equipment.
