Roj Kev Paub - Carbon Dioxide
Vim li cas cov dej qab zib fizz thaum koj qhib nws? Vim li cas cov nroj tsuag "noj" hauv lub hnub ci? Lub tsev cog khoom nyhuv yog ua ntau dua, thiab tag nrho lub ntiaj teb yog tswj cov pa roj carbon emissions. Puas muaj cov pa roj carbon dioxide tiag tiag tsuas muaj kev phom sij?
Carbon dioxide Yog Denser tshaj li huab cua, tuaj yeem yaj hauv dej, thiab yog cov pa roj tsis muaj kob, tsis muaj ntxhiab ntawm chav sov. Nws muaj ib qho xwm txheej dual: nws yog "cov zaub mov" rau cov nroj tsuag hauv photosynthesis, tsis tau nws kuj yog "kev ua txhaum cai" tom qab ua rau lub tsev cog khoom nyhuv. Txawm li cas los xij, hauv cov teb tshwj xeeb, nws ua lub luag haujlwm tseem ceeb.
Hauv kev tua hluav taws, nws yog tus kws tshaj lij ntawm hluav taws kub tua hluav taws! Cov pa roj carbon dioxide tua hluav taws tuaj yeem nrawm nrawm oxygen thiab muab cov hluav taws kub tawm, taws teeb hluav taws xob, tig mus rau qhov chaw nyab xeeb.
Nyob rau hauv kev lag luam khoom noj khoom haus, nws yog "cov khoom siv npuas npuas"! Cov npuas hauv Cola thiab Sprite tshuav lawv lub neej rau CO2, thiab dej khov thiab ua kom cov khoom tsim tshiab undpermed thaum mus ntev ntev.
Hauv kev tsim cov tshuaj lom neeg, nws yog cov khoom siv tseem ceeb! Nws koom rau hauv kev tsim khoom hauv chaw tsim khoom Si Doda tshauv thiab txawm pab "tig cov khib nyiab mus rau cov khoom muaj nqis" - los ntawm reacogen rau synthesize methanol, txhawb cov hluav taws xob ntsuab.
Tab sis ceev faj! Thaum cov confentration carbon dioxide Nyob rau saum huab cua tshaj 5%, tib neeg tuaj yeem muaj kev kiv taub hau thiab ua pa luv; Tshaj 10%, nws tuaj yeem ua rau tsis nco qab thiab tsis ua kev plees. Thaum cov pa roj carbon dioxide ininents lub neej ua cov khoom siv raw rau cog cov photosynthesis, nws tseem yog qhov kev pab txhawb kev nyab xeeb thoob ntiaj teb. Ntsib nws dual xwm, tib neeg yuav tsum tswj cov pa roj los tswj lub ntiaj teb "ua pa sib npaug."
