Qhwa ubushushu bamanzi - ???

Amanzi ... kangakanani na eli lizwi. Ngamanye amaxesha kakhulu ndifuna ukuphucula ngale ndlela imbongi! Eneneni, amanzi - ntonye ubomi. Le ngxelo kuyinyaniso ukuba abemi bonxweme ulwandle, ukuze abemi bomqwebedu. Iimpawu zamanzi kumawaka eminyaka ubukho inzululwazi walukhenketha ubude nobubanzi. Ibiya kuthetha ukuba akukho okuseleyo ayaziwa, kodwa ... makhe ukuhlangabezana nalo, ngathi, ndlela ilula njengoko qhwa amanzi.

Wonke umntu uyazi ukuba abilayo kunye qhwa lamanzi iingongoma eziphambili ezikhethiweyo ngo-1742 ngu Anders Celsius ukudala isikali yakho lobushushu yakhe, kamva yamkelwa kumazwe amaninzi ehlabathini. Kodwa ke kusoloko kukho amanzi amathumba kwi izidanga nekhulu ngumkhenkce e zero? Hayi, akukho njalo. Zininzi iparameters ukuba ungatshintsha kuphela ezi amanani. Makhe siqale ukusuka ekuqaleni.

Okokuqala, lo qhwa amanzi ngunothi degrees kuphela uxinzelelo eqhelekileyo womoya, apho uxinzelelo kucingelwa kwi milimitha asixhenxe anamashumi mathandathu lesigidi. Ngokwehlisa iqondo lobushushu neGauteng i konyuso uxinzelelo lwamanzi, kunye nobushushu elibilayo - lifinyele. Xa uxinzelelo - yonke kanye okwahlukileyo.

Okwesibini, lamanani aphezulu neetyuwa yenza amanzi ngakumbi "ukumelana" kubanda. Le qhwa kweelwandle amanzi amtyuba kunye neelwandle - malunga ezimbini degrees Celsius. Abo ulwandle apho etyuwa ngaphezulu kwe-avareji, iqhwa kubushushu aphantsi.

Yinto eyaziwayo yamanzi yendalo - kweziyobisi owahlukeneyo. Ewe share sengonyama (ngaphezu kwe alithoba anethoba ekhulwini) amanzi iwela iintlobo imichiza leyo luchazwa amabango H2O. Kodwa kukho yinxalenye yamanzi yendalo kwakhona ekuthiwa amanzi "heavy ', yaye" super-heavy'. Kwimeko yokuqala, kwemolekyuli amanzi endaweni athom ezimbini hydrogen abakhoyo athom ezimbini deuterium Isotope yayo kwimeko yesibini - ntathu eziFihliweyo. Phantsi kweemeko eziqhelekileyo, isiqulatho deuterium kunye eziFihliweyo emanzini lisezantsi kakhulu ukuba nempembelelo yabantu okanye izilwanyana. Kodwa deuterium ecocekileyo ebonisa izinto zinetyhefu esezantsi. Kodwa eziFihliweyo, into eqhumayo ukuba ifomu kanzulu nje yingozi. Kodwa, yona, kwindalo ifumaneka kuphela kwifom iyona.

amanzi Tritiated kunye deuterium babe iimpawu zomzimba yemichiza ezahlukeneyo ukusuka njengesiqhelo, amanzi "yethu". amanzi Deuterium ngumkhenkce kwi 3,81 degrees Celsius (at womoya) kwaye amathumba ashushu 101,43. Emanzini tritiated, la manani ziyohluka kancinane: qhwa ingongoma 1.25 kunye ubushushu abilayo degrees 101,6 Celsius.

Iimpawu zamanzi, le ezimbaxa ezibonakala zilula imichiza wafunda ikude lee epheleleyo. Japanese Masaru wafunda, wathi, nokuba intetho amanzi. Ukholelwa ukuba amanzi uyiphendula umculo kunye namandla ezendeleyo amagama. Yaye phezu inqaku! Oku kuthiwa kakuhle zibonakale emva qa amanzi ngohlobo lwe crystals onesiphumo. Kunika umdla ukuqaphela ukuba la magama "sidengendini," yaye ukudlala iingoma kwi "heavy metal" amanzi isimbo ngayo efanayo, kodwa amazwi "enkosi" yena inxulunyaniswa ngothotho imisebenzi for "Inguqu-nguqu Goldberg" harpsichord Ioganna Sebastyana Bach.
