Uyini umoya? Umswakama kanye lokushisa air

Asikwazi ukuphila ngaphandle kwawo. Usizungeze, enikeza ithuba ukuphefumula. Air ... I-mpilo equkethwe ekuqaleni ebusisekile ukuba khona noma yimuphi umuntu osemhlabeni. sizama ukuqonda ngokuningiliziwe Manje okungukuthi emoyeni. Futhi kusukela sihloko ukwazi ukuthi igesi ngezithako zawo, kuyini umswakama walo futhi izinga lokushisa.

ukuphila

Eziphilayo eplanethini yethu sekuneminyaka eminyakeni eyizinkulungwane zezigidi. Futhi ososayensi njalo abanesifiso eziyinhloko ezathonya lokuzalwa kwakhe. Kukholakala ukuthi esinye sezizathu eziyinhloko - ukuthola iplanethi in the okuthiwa habitable zone. Sikhuluma ibanga elikhulu kwenye inkanyezi uhlelo APC, inkathi esemkhathini emhlabeni eksisi, amandla adonsela phansi, yebo, ukwakheka igesi umkhathi. Noma, ngokuvamile, ukuba khona kwakhe. Kalula nje, yingoba libhekisela ikhemikhali esiwuphefumulayo. Kodwa uyini umoya? Futhi iyini nomswakama yayo nge lokushisa? Mayelana-ke kanye nenkulumo.

Air ingxube ubizwa igesi njengoba zemvelo. Bakha emkhathini iplanethi sika. Uma sikhuluma emhlabeni, khona-ke ikakhulukazi siqukethe oksijini nitrogen - 98-99% isiyonke. Ukuze esele ingxenye ewela carbon dioxide, neon, i-hydrogen, futhi argon. Air - yilokhu kuyadingeka kubo bonke abantu futhi ukuba khona evamile nangokuphila sekukonke. Ngaphandle-ke ungeke ukwenze. Ngakho manje siyazi ukuthi emoyeni. Kodwa lokho kubaluleke kangaka?

Zonke ndaba umoya-mpilo. Ngo inqubo ukuphefumula, uyahamba ngegazi ku amaseli yezinto eziphilayo. Kube kwenzeka inqubo namachibi, okuyilona elidingekayo ukuze umuntu amandla. Ukwakheka kwalo ingase yehluke kuye ngesistimu engamamitha noma sezwe izici. Ngokwesibonelo, e kwemizi yasesiFundeni dioxide okuqukethwe carbon uhlale mkhulu kunezinhliziyo ehlathini. Ubuningi oxygen ezintabeni uzokwehla nge okwandisa kokuwa, ngoba kusinda kakhulu kuka-nitrogen. Manje siyazi ukuthi emoyeni futhi yini enquma igesi yayo kwengoma. Futhi kudingeka umoya-mpilo wokushisa fuel ekhaya noma umkhakha. A usebenzisa indlela liquefying okulungiselelwe therefrom amagesi inert. Ngakho, liyini emoyeni, manje sobala.

Kuyini nomswakama?

Isihlobo emoyeni nomswakama wabhekisela isilinganiso yokucindezela ngokwengxenye lamanzi umusi in ingxube yamagesi asemkhathini kuya elihlale umusi ingcindezi ezingeni lokushisa inikezwe. Ngo amafomula kwalesi sibalo okhonjiswe ngesiGreki incwadi φ. Uma sicabangela umswakama, kuba - lemali umswakama ukuthi kuqukethwe eyodwa imitha cubic air. Kodwa kuyinto eyaziwayo ukuthi othile lokushisa emkhathini, kungaba ubambe kuphela ethile esiphezulu okusamanzi. Okusho ukuthi, njengoba linyuka izinga lokushisa - lesi silinganiso uyanda futhi uya ngokuya incipha - uwela. Ngakho-ke, ososayensi kanye waqamba into ezifana umswakama nesihlobo. Ukuze ubone ukuthi amapharamitha asetshenziswayo hygrometers futhi psychrometers.

Uyini umswakama kusukela iphuzu kwemvelo umbono? Lena into ebaluleke kakhulu ngakho. Uma ukubaluleka liphansi kakhulu, abantu baye banda fatigability waphawula Oqala ukungezwa aze agcine isikhundla senqubo yokucabanga evamile, ukuqonda futhi inkumbulo. Futhi-ke, kuyingoti nokuthi amaqabunga omile nolwelwesi lwamafinyila, sebethule microcracks, kulo amagciwane namagciwane. Ukuze ulawule le nkomba livame ukusetshenziswa izinzwa akhethekile humidifiers. Kodwa kwabanye futhi izifunda "ezimanzi" ekhiqizwa emoyeni isimo. Bona, kunalokho, kunganciphisa nomswakama.

Uyini lokushisa?

Temperature - lokhu ingenye impahla yayo, okuyinto waveza ngendlela ambalwa. Inkomba kushintsha njalo. Ezindaweni ezahlukene zomhlaba, futhi, kukhona lokushisa ezahlukene. Uma sicabanga ukuphakama okuyinto eduze kwamanzi, it luyehluka in ezihlukahlukene kakhulu. Ngokwesibonelo, e-Saudi Arabia +58 ºC alotshwa 1922. Ngesikhathi esifanayo omunye iziteshi Antarctic ngo-2004, izinga lokushisa yabonisa irekhodi -91 ºC. Kuye ukuphakama futhi lokushisa izinguquko. Futhi ngokuvamile kwenzeka ngezikhathi.

Emazweni amaningi, izinga lokushisa emoyeni kukalwa ngokwamazinga. lokhu kwenziwa ngokusebenzisa isikali Celsius. Zero usho lokushisa lapho ukuncibilika iqala eqhweni, futhi 100 noma ngaphezulu - amanzi abilayo. Kodwa kuze kube manje, kukhona amazwe ezisebenzisa isikali yakhelwe Fahrenheit. Ngokwesibonelo, e-United States. It isikhawu, ukubaluleka engezansi elimelela ukuncibilika iqhwa, futhi esiphezulu - emanzini abilayo, ihlukaniswe 180 degrees. Ngakho manje siyazi ukuthi kubaluleke kangakanani umoya ukuthi kuyini, futhi umswakama kungani ongaphakeme kuyinto yingozi empilweni.
