Xa sicinga ngamaqondo obushushu abandayo, sinokuba nomfanekiso-ngqondweni wosuku olubandayo lwasebusika, kodwa ngaba wakha wazibuza ukuba injani ingqele enzulu ngokwenene? Uhlobo lwengqele eqhaqhazelisa amazinyo kangangokuba inokukhenkceza izinto ngephanyazo? Kulapho initrogen elulwelo kunye neoksijini elulwelo ingena khona. Ezi zinto zihlala zisetyenziswa kuphando lwezenzululwazi, iinkqubo zonyango, kunye nobugcisa bokupheka. Kule bhlog, siza kugocagoca kwiimpawu zezi khompawundi zimbini kwaye sijonge ilizwe elinomdla lokubanda okunzulu.
Ulwelo lwenitrogen lulwelo olungenambala, olungenavumba, nolungenancasa olubila ku--195.79°C (-320°F). Iqulunqwe ngeemolekyuli zenitrogen eziye zapholiswa kwimeko yolwelo. Enye yeempawu ezikhethekileyo zenitrogen engamanzi kukuba inokukhenkceza ngokukhawuleza izinto xa zidibana. Oku kuyenza ibe luncedo kugcino lwe-cryogenic lwemathiriyeli yebhayoloji, efana nedlozi, iisampulu zethishu, kunye nezinto eziphilayo ezipheleleyo. Ikwasetyenziselwa ukuveliswa kwe-carbon fiber kunye nokupholisa iinxalenye zekhompyutha.
Ulwelo lweoksijini, kwelinye icala, lulwelo oluluhlaza, olungenavumba, nolungenancasa olubila ku--183°C (-297°F). Iquka iimolekyuli zeoksijini eziye zapholiswa ukuba zibe kwimeko yolwelo. Ngokungafaniyo nenitrogen engamanzi, ioksijini elulwelo iyasebenza kakhulu kwaye inokuvutha lula phantsi kweemeko ezithile. Oku kuyenza ibe luncedo kwi-rocket propulsion, i-welding, kunye nokusika isinyithi. Ikwasetyenziswa kunyango lwezifo zokuphefumla, ezifana nesifo esingapheliyo semiphunga (COPD).
Xa kuziwa ekudibaniseni initrogen engamanzi kunye neoksijini engamanzi, sifumana umxube wenitrogen yeoksijini. Le ndibaniselwano inokuba yingozi ngenxa yokwenzeka kwezinto eziqhumayo. Nangona kunjalo, kwiindawo ezilawulwayo, i-oxygen nitrogen ingasetyenziselwa iinjongo ezahlukeneyo, ezifana ne-cryotherapy okanye unyango lokuvuselela ulusu. Ngale ndlela, umxube we-nitrogen engamanzi kunye neoksijini engamanzi isetyenziswa eluswini, nto leyo ebangela ukuba imithambo yegazi ixinzelele kwaye inciphise ukudumba.
Njengoko kukhankanyiwe ngaphambili, ukubanda okunzulu kunokuba noluhlu lwezicelo, kwaye ihlabathi lokupheka alikho. Abapheki banokusebenzisa initrogen elulwelo ukwenza ukutya okunomkhenkce, okufana ne-ayisikrimu okanye i-sorbet, ngokukhenkceza ngokukhawuleza umxube onenitrogen engamanzi. Ngokufanayo, ioksijini engamanzi ingasetyenziselwa ukwenza amagwebu kunye neesosi ezifakwe umoya. Obu buchule buhlala busetyenziswa kwi-molecular gastronomy ukwenza ukuthungwa okukhethekileyo kunye neenkcazo.
Umntu unokuzibuza ukuba siyifumana njani na initrogen engamanzi kunye neoksijini engamanzi, kuthathelwa ingqalelo iindawo zabo zokubilisa eziphantsi kakhulu. Impendulo ikwinkqubo ebizwa ngokuba yifractional distillation, apho umoya ucinezelwayo uze upholiswe de ube lulwelo. Iinxalenye ezahlukeneyo zomoya, ezifana nenitrogen kunye neoksijini, zineendawo zokubilisa ezahlukeneyo kwaye zinokwahlulwa ngokuxutywa kwe-distillation. Le nkqubo ifuna izixhobo ezikhethekileyo kwaye ngokuqhelekileyo iqhutyelwa kwisikali semizi-mveliso.
Ukuqukumbela, iipropathi zenitrogen elulwelo kunye neoksijini engamanzi zibenza babe ngamacandelo abalulekileyo kwiinkalo ezahlukeneyo zesayensi, amayeza, kunye nokupheka. Ezi zinto zinika umbono onomdla kwihlabathi lengqele enzulu kunye neendlela ezintsonkothileyo ezilawula indlela yokuziphatha kwento. Ngophando oluqhubekayo kunye nophuhliso, sinokufumana izicelo ezingaphezulu kwezi khompawundi kwixesha elizayo.
