Mawu Oyamba

Kodi pali madzi pamwezi?Inde, zatero!Pali nkhani yofunika yofufuza zasayansi masiku awiriwa - asayansi aku China apeza madzi amolekyu m'madothi am'mwezi omwe adabwezedwa ndi Chang 'e-5.
Kodi madzi a molekyulu ndi chiyani?Iyi ndi H₂O m'buku la chemistry yakusukulu yapakati, komanso ndi njira yamadzi yomwe timamwa m'moyo watsiku ndi tsiku.

Madzi omwe adapezeka kale pamwezi ≠ mamolekyu amadzi

Anthu ena amati, kodi sitinkadziwa kale kuti mwezi unali madzi?
Zimenezo n’zoona, koma Jin Shifeng, wofufuza mnzake pa Institute of Physics pa Chinese Academy of Sciences, akufotokoza kuti: “Madzi a geology ndi osiyana kwambiri ndi madzi m’moyo wathu watsiku ndi tsiku. Akapezeka NaOH, amaonanso madzi ngati madzi.
Komanso, madzi omwe amapezeka pamwezi amapezeka pazidziwitso zakutali komanso zitsanzo zapansi.
Madzi a m'nthaka ya mwezi omwe adanenedwa kale ndi "madzi" a hydroxyl awa, osati mamolekyu amadzi m'moyo wathu watsiku ndi tsiku.Madzi a molekyulu, H₂O, ndi madzi a moyo wathu watsiku ndi tsiku.
"Pamwamba pa mwezi, chifukwa cha kutentha kwambiri komanso malo opanda mpweya, madzi amadzimadzi sangakhalepo.Kotero, zomwe zapezeka nthawi ino ndi madzi a crystalline.Izi zikutanthauza kuti mamolekyu amadzi aphatikizana ndi ayoni ena kupanga makhiristo.

Momwe madzi amapangidwira pamwezi

madzi a crystalline ndi ofala Padziko Lapansi, monga alum wamba (CuSO₄ · 5H₂O), omwe ali ndi madzi a crystalline.Koma iyi ndi nthawi yoyamba kuti madzi a kristalo apezeke pa Mwezi.
Mwala wamadzimadzi wopezeka m'nthaka ya mwezi.Mawonekedwe a molekyulu anali ₄ NH MgCl3 · 6H₂O.Ngati muli kusukulu ya sekondale, mudzawona powerengera kuti madzi omwe ali mu kristalo ndi ₄ kwambiri.Ndi pafupifupi 41%.
"Awa ndi mamolekyu enieni amadzi omwe, akatenthedwa pang'ono m'chipinda chopanda mwezi, pamtunda wa madigiri 70 Celsius, amatha kutulutsa mpweya wamadzi."Abiti Jin anatero.Inde, ngati ili pansi, akuti iyenera kutenthedwa mpaka madigiri 100 chifukwa cha mpweya.
“Ichi ndi molekyulu yamadzi yeniyeni.Ukatenthedwa pang'ono ndi mpweya womwe umakhala pamwezi, akuti nthunzi yamadzi imatha kutulutsidwa pafupifupi 70 C," adatero Jin.Zoonadi, zikadakhala Padziko Lapansi, ndi kukhalapo kwa mpweya, zikanafunika kutenthedwa mpaka 100 C.

Gawo lotsatira: Phunzirani za mapiri ophulika!

Ngakhale kuti zizindikiro za moyo pa mwezi zikadali nkhani yotsutsana, kupezeka kwa madzi n'kofunika kwambiri pa maphunziro a chisinthiko cha mwezi ndi chitukuko cha zipangizo.Cha m'ma 1970, kusowa kwa mchere wokhala ndi madzi m'nthaka zam'mlengalenga zochokera ku mautumiki a Apollo kudapangitsa kuti pakhale lingaliro loyambira mu sayansi ya mwezi kuti mwezi unalibe madzi.

Kafukufuku mu kafukufukuyu adagwiritsa ntchito zitsanzo za dothi za mwezi zomwe zidatengedwa ndi Chang'e 5 mission.Mu 2020, ntchito yoyamba yobwerera ku China yopanda mwezi, kafukufuku wa Chang'e 5, adatenga zitsanzo za basaltic lunar regolith kuchokera kudera lakutali la mwezi, kuyambira pafupifupi zaka 2 biliyoni zapitazo, ndikupereka mwayi watsopano wophunzirira mwezi. madzi.
