Chidziwitso cha Gasi - Carbon Dioxide
N'chifukwa chiyani soda fizz mukamatsegula? N'chifukwa chiyani zomera "zimadya" padzuwa? Kutentha kwa mpweya kukukulirakulira, ndipo dziko lonse lapansi likuwongolera mpweya wa carbon. Kodi mpweya woipa wa carbon dioxide umakhala ndi zotsatirapo zoipa zokha?
Mpweya wa carbon dioxide ndi wonenepa kwambiri kuposa mpweya, amatha kusungunuka m'madzi, ndipo ndi mpweya wopanda mtundu, wopanda fungo komanso kutentha. Lili ndi chikhalidwe chapawiri: ndi "chakudya" cha zomera mu photosynthesis, komabe ndi "chochititsa" chomwe chimayambitsa kutentha kwa dziko, zomwe zimathandiza kuti kutentha kwa dziko lapansi kuwonongeke. Komabe, m'magawo apadera, imakhala ndi gawo lofunikira.
Mu gawo lozimitsa moto, ndi katswiri wozimitsa moto! Chozimitsira moto cha carbon dioxide chingasungunuke mwamsanga mpweya ndi kuzimitsa moto wamagetsi ndi wamafuta, kutembenuza mkhalidwe wowopsa kukhala chitetezo m’nthaŵi zovuta.
M'makampani azakudya, ndi "wopanga kuwira kwamatsenga"! Ma thovu mu cola ndi Sprite amakhalapo chifukwa cha CO2, ndipo ayezi wowuma (wolimba kaboni dayokisaidi) amagwiritsidwa ntchito ngati firiji, kusunga zokolola zatsopano zisawonongeke panthawi yoyenda mtunda wautali.
Pakupanga mankhwala, ndizofunikira kwambiri! Amatenga nawo gawo pakupanga phulusa la soda ndi urea, komanso amathandizira "kusandutsa zinyalala kukhala chuma" - pochita ndi haidrojeni kuti apange methanol, kuthandizira mphamvu zobiriwira.
Koma chenjerani! Pamene ndende ya mpweya woipa mu mlengalenga kuposa 5%, anthu akhoza kumva chizungulire ndi kupuma movutikira; kupitirira 10%, kungayambitse kukomoka ndi kukomoka. Ngakhale kuti mpweya woipa umathandizira mwakachetechete moyo ngati chinthu chopangira photosynthesis ya zomera, umathandizanso kwambiri pamavuto anyengo padziko lonse. Poyang'anizana ndi chikhalidwe chake chapawiri, anthu ayenera kuwongolera mpweya kuti asunge "kupuma bwino" kwa Dziko Lapansi.
