Bala iilitha ezininzi ngayo amanzi 1 cube

Yintoni na ke amanzi, wonke umntu uyazi. Le fluid lowo ujikeleze aphume empompeni yethu sisele, siya bahlambe kwaye usebenzise zokupheka. Yena yagcwalisa amachibi, iilwandle kunye neelwandle, ikhoyo nokubakho emhlabeni, komhlaba esibhakabhakeni. Wawagalela phezu komhlaba njengoko imvula ngexesha eshushu, ubusika lalugubungela lonke ilizwe ngokohlobo qhwa. Ewe, kwaye umntu phantse asibhozo ekhulwini wenziwe amanzi efanayo. Nkqu ayishiya esikolweni bayazi ukuba formula eekhemikhali amanzi funda njengoko H ₂ Owu ( «ezimbini Al"), yaye uyazi ukuba H - na hydrogen, naphantsi O ekhemisi ukuqonda oksijini.

Ngaphandle amanzi umhlaba udalwe akukho esiphilayo. Zemvelo besoyika kuthi ngenxa yokuba uninzi amanzi kule planethi ayikho kukhuselekile ukuwasela kuba iqulathe isixa esikhulu neetyuwa lichithakale - ulwandle kunye namanzi olwandle. Kwaye ke isitokhwe fresh yamanzi ukuya kutsho kumhla malunga 80.000 kwiikhilomitha cubic. Nantso kakhulu okanye kancinci? Makhe sibone oko uya kulinganiswa elide kangakanani ngo cubic ngeelitha, oko kukuthi, ukufumanisa ukuba zingaphi iilitha zamanzi 1 cube, ukusukela, ukuthetha ngokuthe ngqo, sekhilomitha cubic - oku akukho namnye systemic. Nekhilomitha enye cubic iqulethe billion cubic metres.

Amanani mihle, akunjalo? Amanzi kwi iplanethi yethu ezininzi ngakumbi. Kodwa bangaphi zalo eziqhelekileyo ngakumbi kuthi iilitha? Ngapha koko, asizange ungayilinganisi amanzi cubic metres, siya ukulinganisa umthamo iilitha zokufuma. Ngoko ke, makhe siqonde iilitha ezininzi njani zamanzi cube mnye. Dance ukuqala ukusuka igama. Enye imitha cubic i ityhubhu zinamacala alinganayo semitha enye. Ngoku makhe ukulungiselela ukwakha ityhubhu. Ukuba kule tyhubhu athele selitha yamanzi, umzekelo, ukusuka iinkonkxa ilitha oqhelekileyo okanye ikomityi yokulinganisa, iya kuhlawula kuphela emazantsi ityhubhu. Kwaye ke impendulo yalo mbuzo: "? Eelitha Bangaphi 1 cube ' - singakwazi ukufumana kuphela ukuba uligcwalise tyhubhu ukuya phezulu.

Kucacile ukuba isebenza ingqayi yelitha akukho mntu itephu ityhubhu ofuna. Ngoko ke, unako ukusebenzisa i-emele okanye ukwakha nje ityhubhu ezincinane. Ndiya kwenza yonke siyazi yaye siyazi ukuba indlela elula ukwahlula ngo 10. Ngoko ke ukulungiselela ukwakha ityhubhu macala ngo decimeter. imbiza yethu bayizalisa le tyhubhu ukuya phezulu! Halala!

Ngoku kubala kunokwenzeka kancinane ukuba zingaphi iilitha zamanzi cube mnye. Ukuba ilitha enye ilingana ukuya kwenye decimeter cc, kufuneka nje ukuba ukubala ezininzi ngayo ezi decimeters cubic cubic meter. Xa sithatha isikwere, kuyenzeka ukuba ukubala ngokukhawuleza - bona kanye-100, oko kukuthi, 10 kwinqanaba lesibini. Ke thina asamkelanga isikwere kunye ityhubhu. Ngoko ke, zingaphi iilitha zamanzi 1 cube? Injalo loo nto, kanye 1,000.

Kufuneka ukuzingisa ngokwaneleyo ukuze isebenze amaxesha 1,000 kunye kwembiza ilitha? Kucaca oko. A izibalo, okanye mandithi nokuba arithmetic, wanceda ukwenza iphulo nje enye yamanzi. Ngoku siyazi kakuhle ukuba zingaphi iilitha zamanzi 1 ityhubhu. Sinako ukuguqula kuphela cubic metres ayi cubic, kwaye kusenokwenzeka ukuba ukubala oko unikezelo lwamanzi ngeyona emhlabeni.

Okunye okunika umdla kukuba enye ilitha esulungekileyo yamanzi (Yek) phantsi kweemeko eziqhelekileyo inobunzima kanye lohamba nekhilogram enye. ke ngoku, esazi iilitha bangaphi zamanzi 1 cube, sinako ukubala, ubunzima lilonke amanzi ngeyona emhlabeni. Kwaye ukuba ufuna ukwazi ubunzima lilonke amanzi olwandle kunye neelwandle, ngoko kufuneka akhumbule ukuba ityuwa mninzi amanzi ingaphezulu kwe ezintsha, yaye ngoko bahlole selitha yamanzi anetyuwa kufuneka ibe ngaphezulu.
