Helium Part 02!
DIVING: Helium is a major component of the gas mix deep sea divers breathe while underwater.
AIRBAGS: Helium and argon gas are used in combination to inflate the airbags of newer cars.
Helium has the lowest melting point and boiling point of any element. To turn helium into a liquid, it must be cooled to an extreme temperature of –269°C (–452°F). Liquid helium is used to make things very cold.
MRI SCANNERS: Helium is a coolant gas for the superconducting magnets in MRI scanners and NMR spectrometers
Large Hadron Collider, CERN, Switzerland: A particle accelerator is a machine that smashes atoms together: this one uses liquid helium to cool its parts.
Airship: This airship contains large quantities of helium to make itself lighter than air.
Rocket helium tank: Helium will fill up a rocket’s fuel tanks as they empty out during lift-off.
Helium-ion microscope: This powerful microscope can zoom in to view much smaller details than most other microscopes.
Balloon: Party balloon: This balloon contains a mixture of helium and air. Weather balloons filled with helium are sent high into the atmosphere to collect data.
Helium-cooled maglev train: This high-speed train uses a pair of magnets: one to move forward and one to float over the track. Liquid helium is used to maintain the low temperatures required by the superconducting magnets that make a maglev train (shown here in Shanghai, China) float above the tracks.
