Intshayelelo
Akhona amanzi enyangeni?Ewe, kuye kwenzeka!Kukho iindaba ezibalulekileyo zophando lwezenzululwazi kwezi ntsuku zimbini-izazinzulu zaseTshayina zifumene amanzi emolekyuli kwiisampulu zomhlaba wenyanga ezibuyiswe nguChang 'e-5.
Yintoni amanzi emolekyuli?Le yi-H₂O kwincwadi yekhemistri yesikolo esiphakathi, kwaye ikwayifomula yemolekyuli yamanzi esiwaselayo kubomi bemihla ngemihla.
Amanzi afunyenwe ngaphambili enyangeni ≠ iimolekyuli zamanzi
Abanye abantu bathi, besingazi kakade ukuba kukho amanzi enyangeni?
Kuyinyaniso oko, kodwa uJin Shifeng, umphandi onxulumene naye kwiZiko leFiziksi kwiZiko laseTshayina lezeSayensi, uyacacisa: “Amanzi kwinzululwazi yokwakheka komhlaba ahluke kakhulu kumanzi kubomi bethu bemihla ngemihla. ukuba ithe yafunyanwa iNaOH, oko kukuthi amanzi ngokwamanzi.
Ngaphezu koko, amanzi afunyenwe enyangeni afunyanwa ngokubona kude kunye neesampuli zomhlaba.
Amanzi kumhlaba wenyanga athi ngaphambili ngokusisiseko ngulo mkhondo we-hydroxyl "amanzi", kungekhona iimolekyuli zamanzi kubomi bethu bemihla ngemihla.Amanzi e-molecular, H₂O, ngamanzi obomi bethu bemihla ngemihla.
“Kumphezulu wenyanga, ngenxa yobushushu obuphezulu kunye nemekobume yevacuum, amanzi alulwelo akanakubakho.Ke, into ethe yafunyanwa ngeli xesha ngamanzi ayikristale.Oku kuthetha ukuba iimolekyuli zamanzi zidityaniswe nezinye ii-ion ukuze zenze iikristale.
Indlela amanzi akha ngayo enyangeni
amanzi ekristale aqhelekile eMhlabeni, njenge-alum yenyongo eqhelekileyo (CuSO₄ · 5H₂O), equlethe amanzi ayikristale.Kodwa eli lixesha lokuqala lokufunyanwa kwamanzi ekristale eNyangeni.
Le crystal enamanzi ifumaneka kumhlaba wenyanga.Ifom yemolekyuli yayiyi-₄ NH MgCl3 · 6H₂O.Ukuba ukwikhemistri yesikolo samabanga aphakamileyo, uya kubona ngokubala ukuba umxholo wamanzi kwikristale ngu-₄ kakhulu.Iphantse ibe ngama-41%.
"Ezi zimolekyuli zamanzi zokwenyani ezithi, xa zishushu kancinci kwi-vacuum yenyanga, kuqikelelo lwe-70 degrees Celsius, zinokukhupha umphunga wamanzi."UNkosazana Jin uthe.Kakade ke, ukuba iphantsi, kuqikelelwa ukuba kufuneka ifudunyezwe kwii-degrees ze-100 ngenxa yomoya.
“Le yimolekyuli yamanzi yokwenyani.Xa kushushu kancinci phantsi kweemeko zevacuum enyangeni, kuqikelelwa ukuba umphunga wamanzi unokuphuma malunga ne-70 C,” utshilo uJin.Ewe, ukuba bekuseMhlabeni, kunye nobukho bomoya, bekuya kufuneka ukuba ifudunyezwe ukuya kutsho kwi-100 C.
Inyathelo elilandelayo: Funda iintaba-mlilo!
Ngelixa iimpawu zobomi enyangeni zisengumxholo ekuphikiswana ngawo, ubukho bamanzi bubalulekile kwizifundo zokuvela kwenyanga kunye nophuhliso lobutyebi.Malunga ne-1970, ukungabikho kweeminerali ezithwala amanzi kwiisampulu zomhlaba wenyanga ukusuka kwimishini ye-Apollo kwakhokelela kwingcinga esisiseko kwisayensi yenyanga yokuba inyanga yayingenamanzi.
Uphando kolu phononongo lusebenzise iisampulu zomhlaba zenyanga eziqokelelwe yi-Chang'e 5 mission.Ngo-2020, iSampuli yokuqala yaseTshayina yokubuya yesampulu engakhange iqhutywe, iChang'e 5 probe, yaqokelela iisampulu ze-basaltic lunar regolith ukusuka kwindawo ekwinqanaba eliphezulu lenyanga, elisusela malunga ne-2 yeebhiliyoni kwiminyaka eyadlulayo, libonelela ngamathuba amatsha okufunda inyanga. amanzi.
