Indlela esindayo kuyinto ilitha lamanzi? Impendulo umbuzo olula

Ukuphendula umbuzo evamile "Iyini isisindo ilitha lamanzi ngalinye?" abantu abaningi ngeke anikele amazwibela lwemibhalo noma zimane nje zithi: "Enye kilogram". Ngempela, ezingeni lokushisa 40 ⁰ C nangaphansi evamile umfutho womoya ngesisindo sezinti ilitha distilled, okungukuthi elingenalo engahluziwe, amanzi ncamashi 1 kg. Futhi ngubani uzokwazi ukuphendula ngokucacile lo mbuzo, "Kuyini isisindo usawoti ilitha umthombo wamanzi ngamunye?" noma "Yini ngoyisiwula kusinda kunakho amanzi - kushisa noma kubanda?"

Ukuze abanjwe, kudingeka uzijwayeze imithetho ezinye eyisisekelo physics. Ukuze ucacise kabanzi kanye kumelwe kuphawulwe ukuthi kulesi sihloko asikhulumi mayelana isisindo yamanzi, futhi ngesisindo sakhe. Umehluko phakathi nale migomo ukuthi isisindo - kuba inkomba eyisisekelo yokuthi liphansi, futhi ulinganiswa khilogremu, isisindo - Inani kubonisa ukuthi amandla ngalo umzimba ngazo nge isisindo ezithile ebusweni; Iyunithi yokulinganisa - Newton.

Ukuze siphendule lo mbuzo kangakanani ilitha lamanzi ukala 1, kuqala ukubona kulokho eba izinkomba esisindo. Yiqiniso kuyi-physics, siyazi ukuthi kukhona amaningi umsebenzi izidakamizwa ukuminyana phezu Coefficient ukusheshisa okudonsa, okuyinto cishe okufanayo phezu bonke ubuso iplanethi futhi 9,81 kg / m ^2. Iyehla iyenyuka kulezi izinto eziningi ezimbili futhi asinike umehluko mass ukwaziswa okufanayo ngaphansi kwezimo ezihlukahlukene.

Okokuqala, ake sixoxe kwabantu ketshezi. Njengoba kushiwo ngenhla, kwabantu ngamanzi acwebileyo ngaphansi kwezimo ezivamile kuyinto 1000 g / m ^3. Uma wengeza ukungcola, ezifana usawoti, the ayajiya, futhi amanzi liba esinzima ngokwengeziwe. Ngokuqondene mass into, kuye ngokuthi lokushisa, kuba Kuxhomeke ekutheni property ndaba ayakhukhumala lapho evuthayo. Lokhu kusho ukuthi ibanga phakathi amangqamuzana iba ezinkudlwana, futhi inani lawo per unit umthamo kuyehla, ngakho-ke, ketshezi kuba lula. Nokho, amanzi has a isici esiyingqayizivele - ke yandisa, ngokungagcini nje ngokubashumayeza, Ukushisa kodwa futhi lwaluyophola (ngokunembile ngenxa ekuqhumeni amapayipi amanzi ebusika). Water has kwabantu esiphezulu ngesikhathi qhwa, kuba lula nge kancane ngeziphambeko isikali ezishisayo. Iyini isisindo litre amanzi ngamunye ngaphansi kwamazinga ahlukahlukene okushisa, uma uthanda, kungatholakala lwemibhalo.

ingcindezi Atmosphere is hhayi okungaka ehlaselwe ekushintshashintsheni ku mass ketshezi njengamafutha lokushisa, futhi umphumela ukuchayeka yayo lokushisa eliphezulu kuyinto ephambene. Ngomfutho ophakeme, ibanga phakathi amangqamuzana kuyehla, ngaleyo ndlela, ngesikhathi esisodwa kanye nenani ivolumu efanayo ngeke emikhulu efana. Ngenxa yalokho, kukhona nokwanda isisindo. Lokhu kungenziwa kalula kubonakala umkhuba, uma kuhlaziywe isilinda umoya onomfutho futhi isilinda air ngaphansi kwengcindezi evamile.

By the way, uyazi ukuthi kungakanani ilitha lamanzi ukala esigxotsheni? amaphesenti 0.5 mkhulu kunezinhliziyo enkabazwe. Lesi simo esiyingqayizivele sibangelwa kubangelwa ukuzungeza eMhlabeni emhlabeni axis awo. Ngenxa-ke, i-centrifugal ukusheshisa inyuka njengenye osondela yenkabazwe, futhi kungakho okwandisa ukusheshisa gravity.

Ukubonisana ngale ndlela, singakwazi ukubala isisindo kangakanani ilitha liquid ngamunye, futhi leli nani ngeke ifane kuye zezemvelo.
