Ilimin gas - carbon dioxide
Me yasa soda fizz lokacin da kuka bude shi? Me yasa tsire-tsire za su "ci" a cikin hasken rana? Tasirin greenhouse yana ƙara tsananta, kuma duk duniya tana sarrafa hayaƙin carbon. Shin da gaske carbon dioxide yana da illa kawai?
Carbon dioxide yana da yawa fiye da iska, yana iya narkewa cikin ruwa, kuma iskar gas ce mara launi, mara wari a cikin ɗaki. Yana da nau'i biyu: shine "abinci" don tsire-tsire a cikin photosynthesis, duk da haka kuma shine "mai laifi" a bayan dumamar yanayi, yana ba da gudummawa ga tasirin greenhouse. Koyaya, a cikin takamaiman fagage, yana taka muhimmiyar rawa.
A bangaren kashe gobara, kwararre ne wajen kashe gobara! Na'urar kashe wuta ta carbon dioxide na iya ware iskar oxygen da sauri kuma ta kashe wutar lantarki da mai, ta mai da yanayi mai haɗari zuwa aminci a cikin lokuta masu mahimmanci.
A cikin masana'antar abinci, shine "mai yin kumfa mai sihiri"! Kumfa a cikin Cola da Sprite suna bin kasancewar su CO2, kuma ana amfani da busasshiyar ƙanƙara (karfin carbon dioxide) don sanyaya, yana kiyaye sabbin kayan amfanin gona marasa lalacewa yayin jigilar nisa.
A cikin samar da sinadarai, abu ne mai mahimmanci! Yana shiga cikin kera soda ash da urea, har ma yana taimakawa "juya sharar gida taska" - ta hanyar amsawa tare da hydrogen don haɗa methanol, tallafawa makamashin kore.
Amma yi hankali! Lokacin da maida hankali na carbon dioxide a cikin iska ya wuce 5%, mutane na iya fuskantar dizziness da rashin ƙarfi na numfashi; fiye da 10%, yana iya haifar da rashin sani da shaƙewa. Yayin da carbon dioxide cikin shiru yana tallafawa rayuwa a matsayin albarkatun ƙasa don photosynthesis na shuka, kuma yana da babbar gudummawa ga rikicin yanayi na duniya. Da yake fuskantar yanayinsa biyu, dole ne ɗan adam ya sarrafa hayaki don kiyaye "ma'aunin numfashi" na Duniya.
