Inhlanganiso Amazing futhi elibanzi amanzi

Iqiniso lokuthi amanzi kuyinto into abakhona acishe yonke indawo, kanye nendima yayo evelele kwetinhlavu kanye nokugcinwa iningi eziphilayo siyazi inkambo esikoleni. Yini enye engase ishiwo izakhiwo ngendlela emangalisayo H ₂ O?

Physics uthi esinye sezici eyinhloko kwabantu amanzi. Lokhu umbandela sicabanga kabanzi. Kuyini lokhu kubalulekile? I kwabantu of amanzi, kanye yini enye into noma impahla ebonisa eziningi kanjani futhi, ngokunembile, lokho eziqukethwe nesisindo se-ivolumu ezithile ketshezi.

Kuyini amanzi emangalisayo ukuze kwabantu bayo kudingeka ukhulume ngokuhlukile? Okokuqala, olungisiswayo eziningana zezinto eziphilayo yayo. Amanzi kungenzeka amanzi ahlanzekile kanye nosawoti, esindayo futhi extra esindayo, abaphilayo nabafileyo. Ngaphezu kwalokho, ngamunye ngokuya ezijwayelekile ezifana komhlaba kanye lamanzi esiphethu, amanzi emvula noma ancibilikise amanzi, ehlelekile futhi ngisho ezomile. Amanzi, njengoba sonke ukukhumbula, kungase kube isimo okuqinile, gaseous noma uketshezi, ngokuthi wokuhlanganisa. Ngokwemvelo, kwabantu amanzi ngosawoti lihlukile kwabantu nemvula noma eqandisiwe.

Hlola izici impahla (kuhlanganise kwabantu amanzi) ngaphansi kwezimo ezivamile, okuyinto lokucabanga asemkhathini ingcindezi ukubaluleka 760 mm HG. Art. futhi lokushisa kuma elilingana no-0 ⁰ C. Ngala imingcele ukushintsha, e ushintsho oluthile kuncike izici futhi izinto. Zonke ngaphandle kwamanzi. I kwabantu of amanzi ngaphansi kwamazinga ahlukahlukene okushisa ngaphansi kwezimo ezivamile bekungeke kube abalulekile.

Ngokungafani nezinye izakhi, ekunciphiseni kwabantu lapho ukufuthelana, amanzi ku ezahlukene kusukela 0 kuya 4 degrees Celsius kwabantu bayo iyakhula. Lapho indlu, ivolumu kanye kwabantu amanzi futhi baziphathe uncharacteristically: umthamo yayo ukwanda kanye liyancipha kwabantu. Kungenzeka ukuba bagcine esimweni lapho amanzi ayiqhwa iphula kwamapayipi amanzi. Ngo izilwane zasendle sici esingavamile H ₂ O ivikela izingqimba engezansi amanzi ukuqanda kulondoloza ukuphila labantu ababehlala lapho. Ngokuqondene ukwanda izinga lokushisa lamanzi, ngemva kumkhawulo 4 ⁰ C, ukuminyana yayo, kanye ngesikhathi lwaluyophola, uqala iwe. amanzi oLwandle siphuka, futhi le mibono, okubonisa kwabantu esiphezulu okushisa sub-zero.

Eqinisweni Okumangalisayo ukuthi amanzi ahlanzekile ngokuphelele ngaphandle kobukhona air Bubbles futhi inclusions ezincane ngenxa yokungcola noma uthuli, kungenziwa selehlile -70 degrees, ngaphandle kumiswa ice noma ukufudumeza ngaphandle abilayo lokushisa umkhawulo lamadigri 150 Celsius. anomalies ezinjalo kungenzeka ngaphansi kwezimo ezithile (yokucindezeleka okwandayo, isibonelo), kanye ukwanda kwabo kungenzeka kuphela ezimweni zaselebhu.

Ngokuvamile, kwabantu amanzi kuthinte khona ukungcola, igesi Bubbles kanye nosawoti Ukwakheka bayo, okwakhiwa ngalo ingcindezi value, i-lokushisa kuma futhi eziningi izici zangaphandle. It is a ndaba elula iyeke mangaza ososayensi nge izakhiwo zabo ngokuphelele kumnandi ngokomzimba, ikhono ukushintsha isakhiwo futhi amakhemikhali ukwakheka.
