Zivo yegesi - kabhoni dioxide
Sei soda fizz paunoivhura? Sei zvinomera zvichigona "kudya" muchiedza chezuva? The greenhouse effect iri kuwedzera kuipa, uye pasi rose riri kudzora kubudiswa kwecarbon. Ko carbon dioxide ine migumisiro inokuvadza chete here?
Carbon dioxide yakakora kupfuura mhepo, inogona kunyungudika mumvura, uye igasi risina ruvara, risinganhuhwi patembiricha yepakamuri. Iine hunhu hwehuviri: ndiyo "chikafu" chezvirimwa muphotosynthesis, asi zvakare ndiyo "mhosva" yekudziya kwepasirese, zvichibatsira mukupisa kwegreenhouse. Nekudaro, mune chaiyo minda, inoita basa rakakosha.
Muchikamu chekudzima moto, inyanzvi yekudzima moto! Chodzimisa moto checarbon dioxide chinogona kukurumidza kuparadzanisa okisijeni uye kudzima moto wemagetsi neoiri, zvichiita kuti mamiriro ezvinhu ane ngozi ave kuchengeteka munguva dzakaoma.
Muindasitiri yezvekudya, ndiyo "magical bubble maker"! Mabhuru ari mucola neSprite anokwereta kuvepo kwawo kuCO2, uye chando chakaoma (solid carbon dioxide) inoshandiswa mufiriji, kuchengetedza zvibereko zvitsva zvisina kuparara panguva yekufambisa kureba.
Mukugadzirwa kwemakemikari, chinhu chakakosha mbishi! Inotora chikamu mukugadzira soda ash uye urea, uye inotobatsira "kushandura marara kuita pfuma" - nekuita nehydrogen kugadzira methanol, inotsigira girinhi simba.
Asi chenjera! Kana iko kusungwa kwe carbon dioxide mumhepo inopfuura 5%, vanhu vanogona kunzwa dzungu uye kupera kwekufema; pamusoro pe10%, zvinogona kutungamirira kukusaziva uye kutadza kufema. Nepo kabhoni dhaikisaidhi ichitsigira chinyararire hupenyu sechinhu chakabikwa chechirimwa photosynthesis, iri zvakare chikamu chikuru kudambudziko remamiriro ekunze pasi rose. Kutarisana nehunhu hwayo hwehuviri, vanhu vanofanirwa kudzora zvinobuda kuti vachengetedze "Kufema" kwePasi.
