Yini esiyaziyo carbon dioxide?

Carbon dioxide (CO ₂₎ - gas ephethe ukunambitheka ngokulambisa lizwakale omuncu, ongenaso umbala noma iphunga. okuhlushwa lalo e- emkhathini Womhlaba ivuliwe isilinganiso mayelana 0.04%. Ngakolunye uhlangothi, ukuba sigcine ukuphila kwakhe ngokuphelele ezingafanele. Futhi ngakolunye - zonke izimila nje ngabe washona ngaphandle carbon dioxide, kusukela nguye "umthombo wamandla" simila. Ngaphezu kwalokho, _i-CO2 Umhlaba amanye uhlobo ingubo. Uma isimo kwakukhona lesi igesi, iplanethi yethu kungaba ongayo kanye izimvula kuyoyeka cishe ngokuphelele.

"Kwengubo Umhlaba»

Ukwakhiwa kwe-carbon dioxide (carbon dioxide, CO ₂₎ kuwumphumela uxhumano ababili izingxenye zalo:-mpilo ne-carbon. Leli igesi yonke indawo lapho kukhona nokusha zamalahle nobe hydrocarbon compounds. Liphinde ezikhishwe ngesikhathi ukuvutshelwa uketshezi futhi umkhiqizo wesilwane nokuphefumula kwezimila womuntu. Kuze kube manje, property carbon dioxide kufundvwe kahle. Kuyaziwa ukuthi le gesi kusinda kunakho emoyeni futhi kungekho nto enemibala emihle ezaziwayo. Lapho kuhlangene amanzi, it yakha carbonic acid, okuyinto kabanzi zonke izinhlobo zophuzo carbonated.

Kungani ososayensi ngokuvamile bathi CO ₂ - i-Quilt kuyiplanethi yethu? Iqiniso ukuthi dioxide carbon sihamba ngokukhululekile eza kithi kusuka isikhala ultraviolet ray abese ecabanga amaza okushisa esikhishwa Earth. Ngakho-ke, ukunyamalala ngokungazelele igesi emkhathini ngokuyinhloko ezizothinta sezulu. Nokho, ematfuba engozini enjalo kuyinto cishe zero, njengoba amandla omlilo ngokhuni, igesi yemvelo, nowoyela kancane kancane kwandisa lokuhlushwa carbon dioxide emkhathini. Futhi manje ukwesaba akulona sezulu kangaka abandayo, njengoba nenqwaba encibilika ice-pole nokwanda ezingeni kwezilwandle ...

iqhwa

In the state ketshezi igesi lilondolozwe amasilinda ngomfutho ophakeme (mayelana 70 atm). Uma uvula i-valve bomkhumbi steel aphume umgodi iqala phuma ... iqhwa. Hlobo luni izimangaliso? Leli qiniso wachaza impela nje. Phakathi kokucindezelwa le dioxide carbon idliwe umsebenzi, okuyinto ezidlula kuyinto kakhulu esingaphansi ukuthi kunesidingo lokwandisa yayo. Ukuze bavale isikhala ukuntula kuphakama CO ₂ is iqeda futhi uguqulwe ube "iqhwa". Njengoba eqhathaniswa ice ezivamile it has eziningi eziwusizo abalulekile: okokuqala, ukuhwamuka yayo kwenzeka ngokuphelele ngaphandle kumiswa izinsalela. Futhi okwesibili, "sokuphumula amandla" iqhwa ngalinye iyunithi isisindo kabili.

isicelo

Carbon dioxide livame ukusetshenziswa njengoba i osebenzelana inert in the wire Welding. Nokho, ngamazinga ashisa kakhulu, noqhekeko kwenzeka lapho kukhululwa oxidizing-mpilo yayo metal. Ngakho-ke, i- wire Welding sengezwe scavengers, ezifana Silicon kanye manganese. Carbon dioxide e namakani evame ukusetshenziswa kwezibhamu womoya kanye Aviamodelirovaniye. Le gesi ketshezi isetshenziswa njengophawu mlilo ngokukhiqiza soda lemonade. Ngaphezu kwalokho, CO2 Carbon dioxide liyasetshenziswa njengendlela ikhodi ukudla okufakiwe (E290). Njengoba sazi sonke kusho ziba ngcono inhlama. Ngaphandle kwalokho, okuqinile carbon dioxide abaningi esetshenziswa lokulondolozwa imikhiqizo ukudla.
