1. Helium ua haujlwm raws li lub zog txhawb zog thiab txhawb nqa rau cov kua - roj foob pob hluav taws, thiab siv dav hauv cov cuaj luaj, dav hlau, thiab lub dav hlau supersonic.
2. Helium yog siv los ua cov roj tiv thaiv thaum lub sij hawm smelting thiab vuam txheej txheem -ib qho tseem ceeb hauv kev tsim nkoj, nrog rau kev tsim cov dav hlau, dav hlau, foob pob hluav taws, thiab riam phom.
3. Muaj cov permeability zoo heev, helium yog siv rau cov cua txias ntawm lub tshuab hluav taws xob nuclear thiab txhawm rau txhawm rau tshawb pom hauv cov kav dej ntawm cov foob pob hluav taws thiab cov tshuab hluav taws xob nuclear, nrog rau ntau yam khoom siv hluav taws xob thiab hluav taws xob.
4. Helium nthuav tawm cov khoom ntawm cov roj zoo tagnrho, ua rau nws yog qhov nruab nrab zoo tshaj plaws rau kev siv hauv vapor- cov ntsuas kub siab uas tsim los rau qhov kub tsis tshua muaj siab.
5. Helium nta qhov hnyav thiab hnyav hnyav thiab tsis yog -flammable; Yog li ntawd nws yog siv los sau cov qij thiab cov raj neon, thiab ua haujlwm zoo tshaj plaws nqa cov pa roj rau balloons thiab airships.
6. Liquid helium enables attainment of cryogenic temperatures approaching absolute zero (-273 degree), ua qhov tseem ceeb rau kev tsim cov khoom siv superconducting.
7. Raws li cov pa roj inert, helium muaj qis solubility hauv cov ntshav tshaj nitrogen; yog li ntawd, nws pom cov nyhuv narcotic tsawg dua li nitrogen. Vim li no, helium feem ntau sib xyaw nrog oxygen los tsim cov pa roj sib xyaw ua pa sib sib zog nqus - hiav txwv divers.
