Ubumenyi bwa gaze - dioxyde de carbone
Kuki soda ifunga mugihe uyifunguye? Kuki ibimera bishobora "kurya" ku zuba? Ingaruka ya parike igenda irushaho gukomera, kandi isi yose igenzura ibyuka bihumanya. Dioxyde de carbone koko igira ingaruka mbi gusa?
Dioxyde de carbone ni mwinshi kuruta umwuka, irashobora gushonga mumazi, kandi ni gaze itagira ibara, impumuro nziza mubushyuhe bwicyumba. Ifite kamere ebyiri: ni "ibiryo" ku bimera biri muri fotosintezeza, nyamara kandi ni "nyirabayazana" w’ubushyuhe bukabije ku isi, bigira uruhare mu ngaruka za parike. Ariko, mubice byihariye, bigira uruhare runini.
Mu rwego rwo kurwanya umuriro, ni umuhanga mu kuzimya umuriro! Kuzimya umuriro wa karuboni irashobora kwihutisha gutandukanya ogisijeni no kuzimya umuriro w'amashanyarazi na peteroli, bigahindura ibintu biteye akaga mu mutekano mu bihe bikomeye.
Mu nganda zibiribwa, ni "magic bubble maker maker"! Ibibyimba muri cola na Sprite bigomba kubaho kuri CO2, kandi urubura rwumye (dioxyde de carbone ikomeye) rukoreshwa mugukonjesha, bigatuma umusaruro mushya udahumanye mugihe cyo gutwara intera ndende.
Mu musaruro wimiti, nibikoresho byingenzi! Ifite uruhare mu gukora ivu rya soda na urea, ndetse ifasha "guhindura imyanda ubutunzi" - mu gukoresha hydrogène kugirango ihuze methanol, ishyigikira ingufu z'icyatsi.
Ariko witondere! Iyo kwibanda kuri dioxyde de carbone mu kirere kirenga 5%, abantu barashobora kugira umutwe no guhumeka neza; hejuru ya 10%, birashobora gutuma umuntu atazi ubwenge no guhumeka. Mu gihe dioxyde de carbone ishyigikira bucece ubuzima nkibikoresho fatizo bya fotosintezeza y’ibimera, nayo igira uruhare runini mu guhangana n’ikirere ku isi. Guhangana na kamere yacyo ebyiri, ikiremwamuntu kigomba kugenzura imyuka ihumanya ikirere kugira ngo isi igumane "guhumeka neza."
