Ulwazi lwegesi - I-Carbon Dioxide
Kungani i-soda fizz lapho uyivula? Kungani izitshalo "zidla" elangeni? Umphumela we-greenhouse usethe xaxa, futhi umhlaba wonke ulawula ukuphuma kwekhabhoni. Ingabe i-carbon dioxide inemiphumela elimazayo kuphela?
I-Carbon Dioxide I-denser kune-air, ingancibilika emanzini, futhi igesi engenamibala, engaphumeleli emazingeni okushisa asekamelweni. Inemvelo embaxambili: "Ukudla" kwezitshalo ezise-photosynthesis, nokho "futhi" yi- "Culprit" ngemuva kokushisa komhlaba, okufaka isandla ekutholeni ukushisa. Kodwa-ke, emasimini athile, idlala indima ebalulekile.
Emkhakheni wokulwa nomlilo, uchwepheshe ekucimeni imililo! Isicishamlilo somlilo we-carbon dioxide singasheshe sihlukanise umoya-mpilo futhi sikhiphe imililo kagesi neyomafutha, siguqula isimo esiyingozi siphephe izikhathi ezibucayi.
Embonini yokudla, yi- "Magical Bubble Maker"! Ama-bubble eCola nasePropte akweleta ubukhona bawo kwi-CO2, ne-Icebo Lomile (i-solid carbon dioxide) isetshenziselwa isiqandisi
Ekukhiqizweni kwamakhemikhali, kungukubonakalayo okubalulekile okuluhlaza! Ibamba iqhaza ekwenziweni kwe-soda ash kanye norea, futhi isiza "ukuguqula imfucuza ibe yingcebo" - ngokuphendula nge-hydrogen ukuhlanganisa i-methanol, isekela amandla aluhlaza.
Kepha qaphela! Lapho ukugxila kwe I-Carbon Dioxide Emoyeni kudlula ama-5%, abantu bangathola isiyezi kanye nokuphefumula; Ngaphezu kwe-10%, kungaholela ekungazifezeke kanye nokwehla. Ngenkathi i-carbon dioxide isekela buthule impilo njengento engavuthiwe ye-plant photosynthesis, futhi ingumthelela omkhulu kwizinkinga zesimo sezulu emhlabeni jikelele. Ukubhekana nemvelo yayo embili, ubuntu kufanele balawule ukuphuma ukuze balondoloze 'ukulinganisela okuphefumulayo komhlaba.'
