Ngegama le- uketshezi (noma uketshezi) olunye lwezinguquko zombuso udaba olungaba nalo luyaziwa, ikakhulukazi olwe-a isimo segesi sidlulela esimweni soketshezi.
Inqubo yenzeka ngenxa yomphumela wengcindezi kanye nokushisa, kuze kufike ezingeni labo bonke amagesi kukhona izinga lokushisa ngezansi lapho, ngokusebenzisa ingcindezi enkulu ngokwanele, zingaguqulwa zibe uketshezi. Ngendlela efanayo, noma ngabe ingcindezi inkulu kangakanani, igesi ayikwazi ukuncibilikiswa ngokushesha lapho izinga layo lokushisa lidlula ibanga elithile.
Ukutholwa kanye Nezicelo
Inqubo yokushintsha kombuso kusuka kugesi kuye ketshezi ngokusebenzisa izingcindezi eziphakeme naphansi amazinga okushisa Kutholwe nguMichael Faraday ngo-1823, kanti isifundo esibaluleke kunazo zonke esalandela esenziwa nguThomas Andrews, okwathi ngo-1869 wathola ukuthi igesi ngalinye linezinga lokushisa elibucayi ngenhla okungenakukhinyabezeka, futhi kunalokho, lapho ukucindezelwa kwenziwa, kuyenzeka ukuthi ijubane lama-molecule namabanga aphakathi kwawo ancipha aze athole ukuguquka kwesimo.
Phakathi nekhulu lama-20, ukuncibilika kwamagesi kwaba nendima ebalulekile ezindabeni izikhali, ikakhulukazi ngesikhathi seMpi Yezwe.
Okunye ukusetshenziswa okubaluleke kakhulu okunikezwa inqubo yoketshezi uketshezi ukuthi kuyo bangakwazi hlaziya izakhiwo eziyisisekelo zama-molecule kagesi, ukuze uwagcine. Ngakolunye uhlangothi, kusetshenziswa amagesi amaningi amponjwana ezindaweni ezahlukahlukene zemithi ukuze kuthuthukiswe impilo yabantu.
Ugesi wemvelo oketshezi
Kodwa-ke, isibonelo esijwayelekile kakhulu soketshezi yi- igesi yemvelo encibilikisiwe noma ecindezelweyo, igesi yemvelo esetshenziselwe yona ezokuthutha ifomu eliketshezi. Lezo zindawo lapho kungasizi khona ukwakha ipayipi legesi noma ukukhiqiza ugesi, zinxusa ukuthuthwa kukaphethiloli ngale ndlela: igesi lapha ithuthwa njengoketshezi ekucindezelekeni komkhathi nasekushiseni kuka -162 ° C, ngamaloli amakhulu lokho kuvame ukubonwa emigwaqweni yamazwe amaningi.
Lolu hlobo lwegesi alunambala, alunaphunga, alunabo ubuthi, futhi luphephe kakhulu, kanye nokwehlisa izindleko zengqalasizinda nokukhiqizwa kwamandla kumaphrojekthi amaningi.
Ukuchithwa kwenhlabathi
A uketshezi lokho kwenzeka ngokungazikhetheli yilokho okwenzeka lapho eminye inhlabathi inyakaziswa ukuzamazama komhlaba, bese bekhipha izinto abanazo ngesimo segesi, kubangele ukuthi inhlabathi iwele namanzi ngaphakathi.
Kubaluleke kakhulu ukuhlaziya ubunjalo bomhlabathi ezindaweni ezivame ukuzamazama komhlaba, ngoba ukulahleka kokumelana nenhlabathi kulezi zimo kwenza izakhiwo ezibekwe lapho zingakwazi ukuhlala zizinzile, zihudulelwa enhlabathini enamanzi.
Izibonelo zokuchithwa
Ukuncibilika komoya, ukufeza amagesi awakhayo, ikakhulukazi i-oxygen ne-nitrogen, esimweni sobumsulwa. Lokhu kwakubalulekile embonini yempi.
- Ukucindezelwa kwegesi yemvelo.
- I-chlorine enamanzi, yokuhlanzwa kwamanzi.
- Ukuchithwa kwe-helium, okusetshenziselwa ukusetshenziselwa ukwengeza ozibuthe, noma ezindabeni ezihlobene nokuzwakala kwamandla kazibuthe.
- Ithangi le-nitrogen.
- I-nitrogen ewuketshezi, esetshenziselwa i-dermatology kanye ne-insemination yokufakelwa.
- Ama-lighters nama-carafes, aqukethe igesi ewuketshezi etholwe ngenxa yoketshezi.
- Ukuthuthwa kwendle kwezimboni kusetshenziswa izinhlobo ezahlukene zamagesi ancibilikisiwe.
- I-oxygen yamanzi, esetshenziselwa iziguli ezinenkinga yokuphefumula.
- I-LP gas, i-petroleum enamanzi, esetshenziselwa ukufriji nomoya opholile.
