以上所有嘅氣體都可以係空氣入邊搵到。

1. Noble gases ( 貴氣體, e.g. Helium氦, Neon氖, Argon氬 ... )
2. Carbon dioxide ( 二氧化碳, CO2 )
3. Nitrogen ( 氮, N )


係空氣中所佔嘅成份 :
Noble Gas ( 貴氣體 ) 0.93%
Carbon dioxide ( 二氧化碳 ) 0.03%
Nitrogen ( 氮 ) ~70%

all of above gases ...

breathed air was as followed:

noble gases:0.9%

CO2:0.2-0.3%

nitrogen:76%

全部都可以搵到架..
係空氣中，
noble gases含0.9%
carbon dioxide含0.03%
nitrogen就含78%

All

Nitrogen about 70%
Carbon dioxide 0.03%
Noble Gas(Argon,Neon...) 0.09%
