Isimo amanzi ngokwemvelo. Amanzi amafomu ezintathu wokuhlanganisa

Amanzi - yisona esikhulunywa abantu abaningi emhlabeni ndaba. Kuyinto ingxenye yawo wonke amangqamuzana aphilayo, Ngakho-ke, kubaluleke kakhulu wokusekela ukuphila eMhlabeni. Siyazi okuningi amanzi, kodwa namanje Awuvulanga izimfihlakalo zayo.

Amanzi asizombelezileko

Amanzi ibhalansi - ngesisekelo eziphilayo eplanethini yethu. Eziningi zazo emhlabeni - kuba izilwandle nezilwandle. Bagxila 97% we ketshezi. Labo abasele abanga-3% - imifula, amachibi, amachibi kanye komhlaba kanye Umhwamuko uhamba emkhathini. Izimila nezilwane ukuze baphile nsuku kudle reviver.

Amanzi - kungcono ingxenye yomzimba womuntu. Ngamunye amangqamuzana amehlo ethu okuthiwa ezingaphezu kwesigamu siqukethe ketshezi. Igazi eligeleza emithanjeni yethu - kuyinto 82% amanzi. Imisipha futhi isikhumba aqukethe ke 76%. Ngokumangalisayo, ngisho amathambo ukubunjwa yabo kukhona 30% amanzi. Okuqukethwe kwalo encane kunazo zonke koqweqwe lwawo kwamazinyo -% 0.3 kuphela.

Inani Isisindo amanzi kule mbulunga enguMhlaba - amathani angaphezu kwezigidi eziyizinkulungwane eziyizigidi ezingu-2.

Yiziphi 3 uthi yamanzi imvelo?

Ukuze umbuzo "Kuyini amanzi?" cishe yonke ukusabela ngaphandle kokunqikaza: "Kuyinto uketshezi". Ngempela, kaningi ngaphezu thina asetshenziselwa Ziyancibilika amanzi zemvelo. Kodwa eqinisweni, ke lungeza ngezindlela eziningi ezihlukahlukene, ngokuphelele ukuhluka omunye komunye.

Amanzi ezintathu zithi:

• ewuketshezi;
• isimo umusi;
• okuqinile ifomu sesisonke - ice.

Amanzi - ketshezi

Isimo liquid amanzi etholakala emvelweni kithi kaningi. Kuleli fomu ka H ₂ O kungaba ku uhla lokushisa kusuka 0 kuya 100 degrees Celsius. Kuyinto lokhu isimo ngokomzimba amanzi emifuleni, ezilwandle, izilwandle emvuleni.

Le into esobala ayinakho ukunambitheka, akukho ukuhogela, akukho ubunikazi. Liquid kubonakala zazivuma kakhulu, kodwa ngesikhathi esifanayo it has nethonya elikhulu. Isimo liquid amanzi ngokwemvelo kuyivumela chaza izinto eziningi. Imifudlana yamanzi ongabhubhisa amatshe ukwakha emhumeni, futhi ngaleyo ndlela ukushintsha sendawo planethi.

Ifomu liquid H ₂ O isetshenziswa yonke indawo ekuphileni kwansuku zonke. Okokuqala, zonke izidalwa eziphilayo, kuhlanganise nomuntu, udinga ukudla nsuku zonke a kwamahala kwenani elithile lamanzi. Okwesibili, kudingeka ke ukuze uhlanzeke. Nsuku zonke senza ugeza noma eshaweni izikhathi eziningana ngosuku, nokuphakanyiswa kwezandla zami, sikhule imifino nezithelo emasimini abo, babanike ngenkasa, bahlanze izingubo zabo. Ngaphandle ngisho ukucabanga, zonke lezi izinqubo, sisebenzisa namanzi.

Iqhwa - amanzi ngefomu okuqinile

H ₂ O kusukela ketshezi ludlulele esiqinile isimo aggregate at okushisa aphansi ngezansi 0 degrees Celsius. Into ezithakazelisayo wukuthi cishe zonke izinto ukupholisa ziyancipha emqulwini, futhi amanzi, kunalokho, umnkantsha, uyanda. Uma kunjalo-ke kuyinto esobala futhi kungekho nto enemibala emihle, ke lapho eba yiqhwa zingase ziba mhlophe ngenxa ingress emoyeni ku izinhlayiya zeqhwa.

Ngokungavamile, ukuthi ngesikhathi esifanayo ice crystal isakhiwo ungaba eziningi ezihlukahlukene. Isimo okuqinile yamanzi nemvelo - a zeqhwa giant, uqweqwe shiny ice emfuleni, ishq ezimhlophe kweqhwa, icicles elenga ophahleni.

Ice ibaluleke kakhulu izinto ezenziwa abantu futhi kunomthelela omkhulu ekugcinweni zokuphila eminingi engokwemvelo. Ngokwesibonelo, lapho umfula iqina ke wenza umsebenzi zokuzivikela, nokugcina Echibini kusukela okokuqandisa eminye, kanjalo ekuvikeleni izwe ngaphansi kwamanzi.

Kodwa njengoba iqhwa kungabangela izinhlekelele zemvelo esibhubhisayo. Ngokwesibonelo, isichotho, iqhwa izakhiwo kanye izindiza, phansi okokuqandisa, ice izikhukhula zeqhwa ezintabeni ze.

Ekuphileni kwethu kwansuku zonke sisebenzisa amanzi ayiqhwa njengoba Isibandisi, ekubunjweni cubes ezincane ice e isiphuzo kuphole kubo. Ngokufanayo, ungakwazi kuphole ukudla nemithi okuyingozi.

umhwamuko

Amalahle uketshezi 100 ° C, singabona kwathatha isimo gaseous yamanzi. Emvelweni, singabona le yamanzi ngendlela amafu, inkungu, umusi, phezu imifula, amachibi nezilwandle ngokushintsha isimo sezulu, noma nje nomswakama eliphezulu.

Esimweni njalo amanzi usayizi amancane ebavumela ozoba ngomhlaka isisindo. Asikwazi uqaphela khona umswakama emoyeni kuphela uma kwandisa, futhi kukhona amafu noma inkungu.

Ngokuvamile isimo gaseous lamanzi kungaba wusizo ekuphileni kwansuku zonke. Man isebenzisa umusi lula ayina emva ukuwasha. Okusanda kwakukhona ezincwadini ekhethekile, esekelwe umsebenzi okuyinto wabeka kumiswa umusi. Lokhu umusi ugesi. Sinenkosi nezici eziningi, owayevelele kubo - ekulweni ukungcola namagciwane. Futhi inqubo vaporization usukela isibonelo humidifier yasekhaya.

Ukuhambisa amanzi esimweni omunye komunye udlala indima emikhulu uhlanzekile inqubo. Kuphela phakathi ukuhwamuka, ukuqanda ukuncibilika uquqaba omkhulu wamanzi kungaba samoochistitsya.

Amanzi kunoma isiphi isimo aggregate - lena okubaluleke kakhulu. I Bedouins, abaphila ukuphila ayohlala ehlane, bathi kuyabiza kakhulu kunegolide. Kodwa ngisho nalabo kungukuthi ihlangabezana nezinkinga ukuntuleka kwamanzi, ukusula ubuhlobo enkulu phakathi kwakhe nokuphila.
