cooling superconductors
The three main uses of ships are transportation of goods and people, fishing, and military operations.
The main gases in Saturn's atmosphere are hydrogen and helium, with small amounts of other gases like methane and ammonia. Helium is the second most abundant gas in Saturn's atmosphere after hydrogen.
helium is used to cool superconducting magnets in mri scanners as helium is lighter then air airships use them as gasses
Technically Helium is classed as a Noble gas and has a MW of 4g/mol.
Hydrogen and helium
The three main parts to a ballon is the ballon itself, the gas inside it (air or helium), and the knot that keeps the gas inside.
Advertising signs and lighting are the main uses

Hydrogen and helium
Helium is lighter than air. So balloons or air ships filled with helium will float.
Mostly Bollons.
It uses gas from the sun.
Helium is chemically inert and does not form any compounds
