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.

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. It was discovered in 1868 due to a new yellow line in the solar spectrum wavelength of 587.49 nanometers found by Pierre-Jules-César Janssen following a solar eclipse; it was astronomer Sir Norman Lockyer who named it helium, after the sun. Helium is used because helium is absorbed and released by human tissue faster than other elements, such as nitrogen.
Interesting Helium A helium-filled balloon floats because helium is lighter than the air around it. That's why helium is a useful gas for lifting things into the air. The next time you watch a professional football Some of the most critical uses for helium are in the medical industry. Helium is combined with oxygen for the treatment of asthma, emphysema, and other respiratory problems because the combination gets to the lungs much quicker than oxygen treatment alone. Helium’s also needed for… 8.

Its existence was chemistry. In fact, Earth doesn't even have enough gravity to retain any helium. Helium facts and fun. Helium is the second most abundant element in the universe. Helium gas is used to inflate blimps, party balloons and even scientific When pressurised enough it becomes liquid.

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 .
According to the American Physical Society, most helium in the United States is used in industry and in cooling the magnets in magnetic resonance imaging (MRI) machines. Only about 3 percent of the
This is the fate of the helium in our balloons. Helium is used to cool superconductor magnets overheating. This is necessary during their optimal operation.
Hence, it is used in filling balloons for meteorological observations. It is also used in gas-cooled nuclear reactors.
