Kodi tikudziwa chiyani za carbon dioxide?

Mpweya wa carbon dioxide (CO ₂ ) ndi gasi losavuta kumva, lopanda mtundu kapena fungo. Zomwe zili padziko lapansi zimakhala pafupifupi 0.04%. Pa dzanja limodzi, kuti tikhalebe ndi moyo, ndizosayenera. Ndipo pambali inayo - popanda carbon dioxide, zomera zonse zidzangowonongeka, chifukwa ndi "chitsimikizo cha zakudya" kwa zomera. Kuwonjezera apo, pa Dziko lapansi, CO ₂ ndi bulangeti. Ngati kulibe mpweya m'mlengalenga, dziko lathu lapansi likanakhala lozizira kwambiri, ndipo mvula ikanatha pafupifupi kwathunthu.

Mapangidwe a carbon dioxide (carbon dioxide, CO ₂ ) amapezeka chifukwa cha kuphatikiza zigawo zake ziwiri: mpweya ndi carbon. Mpweya uwu umapangidwa paliponse pamene magetsi a malasha kapena ma hydrocarbon amayamba. Amatulutsanso panthawi yomwe imathirira madzi ndi zakumwa komanso kupangidwa ndi kupuma kwa nyama ndi anthu. Mpaka pano, katundu wa carbon dioxide akhala akuphunzira bwino. Zimadziwika kuti mpweya uwu ndi wolemetsa kuposa mpweya ndi wopanda mtundu. Pogwiritsa ntchito madzi, amapanga carbonic acid, yomwe imagwiritsidwa ntchito mosiyanasiyana m'mabotolo osiyanasiyana.

N'chifukwa chiyani asayansi nthawi zambiri amanena kuti CO ₂ ndi bulangeti yathu? Zoona zake n'zakuti carbon dioxide imadutsa mwachangu mazira a ultraviolet omwe amabwera kuchokera mlengalenga , ndipo amawonetsera mafunde omwe amayendetsedwa ndi dziko lapansi. Choncho, kutaya kwadzidzidzi kwa mpweya umenewu kuchokera m'mlengalenga kungakhudze kwambiri nyengo. Komabe, kuthekera kwa masokawa ndi zero, chifukwa kutentha kwa nkhuni, gasi, mafuta ndi mafuta pang'onopang'ono kumawonjezera mpweya wa carbon dioxide m'mlengalenga. Ndipo tsopano sitiyenera kuopa nyengo yozizira kwambiri, koma mchere umasungunuka pamapiri a glaciers ndikukula msinkhu wa Nyanja ya World ...

Mu madzi amtunduwu, mpweya uwu umasungidwa mu-high-pressure cylinders (pafupifupi 70 Atm). Ngati mutsegula valavu ya chotengera chotere, chipale chofewa chiyamba kutuluka mu dzenje .... Ndi zozizwitsa zotani? Mfundo imeneyi ikufotokozedwa mophweka. Pamene carbon dioxide ikuponderezedwa, ntchito imagwiritsidwa ntchito, yomwe imakhala yochepa kwambiri kuposa yofunikira kuti ikule. Pofuna kubwezeretsa vutoli, CO ₂ yakhuta kwambiri ndipo imakhala "madzi ouma". Poyerekeza ndi ayezi wamba, amakhala ndi ubwino wambiri: poyamba, kutuluka kwake kumapezeka kwathunthu, popanda mapangidwe. Ndipo kachiwiri, "kuzizira" kwa madzi oundana pa unit weight ndi kawiri izo.

Kawuni ya diyaboni imagwiritsidwa ntchito ngati chimbudzi chosakanizika ponyamula ndi waya. Komabe, kutentha kwake kumatha kuchitika ndi kutulutsa oksijeni-oxyidizing oksijeni. Choncho, mu waya yowonjezera yonjezerani deoxidants, monga silicon ndi manganese. Mpweya woipa m'zakani umagwiritsidwa ntchito kwambiri pamfuti za mlengalenga komanso mu ndege. Gasi wamadzimadzi amagwiritsidwa ntchito ngatizimoto zozimitsa moto komanso kupanga chomera ndi soda. Komanso, carbon dioxide CO2 imagwiritsidwanso ntchito monga chakudya chowonjezera (code E290). Ndipo monga njira zodziwika bwino kumasula mtanda. Kuwonjezera apo, mpweya woipa wa carbon dioxide umagwiritsidwa ntchito kwambiri pofuna kuteteza zakudya zopangira chakudya.
