Iipropati Physical amanzi

Amanzi yenye izinto eziphambili ukuba ukuqinisekisa ubukho komhlaba kunye ubuntu. Le yinkalo eyodwa ngokupheleleyo, ngaphandle apho ayikwazi kuba ubomi zonke izidalwa. Ezinye chemical kunye neempawu zomzimba ze yamanzi ezikhethekileyo.

Ukubaluleka kwalo mba ayikwazi nemikhuba. Amanzi ligubungela inxalenye enkulu planethi, uyila iilwandle, iilwandle, imilambo kunye nezinye amanzi. Ibandakanya ngqo kukwenziwa imozulu kunye nemozulu, ngaloo ndlela iimeko ezithile ubukho kule okanye kwikona iplanethi.

Ngokuba izinto ezininzi, ukhonza yokuhlala. Ukongeza, phantse yonke into ephilayo ngendlela enye okanye enye into ephuma emanzini. Ngokomzekelo, umxholo ngawo umzimba womntu-70 ukuya kwi-90 ekhulwini.

Iimpawu ezibonakalayo yamanzi: inkcazelo emfutshane

Kwemolekyuli yamanzi yahlukile. Ifomula Ngokuqinisekileyo oko kuye kwafika kubo bonke: H2O. Kodwa nantsi ezinye iimpawu ezibonakalayo amanzi zixhomekeke ngqo kwi isakhiwo iimolekyuli yayo.

Kwindalo, amanzi ikhona ezintathu kwiimo udibaniso. Phantsi kweemeko eziqhelekileyo, le nto ulwelo ngaphandle umbala, ivumba kunye nemvakalo. Xa lobushushu uyawa namanzi crystallizes abe ngumkhenkce. Ngenxa yokwanda lobushushu, ulwelo ludlulele kurhulumente sukube - umphunga.

Amanzi luphawulwa ezixineneyo, nto leyo malunga 1 gram nganye sentimitha cc. Uxhaphazelayo amanzi kwenzeka xa amaqondo obushushu bavuselwa nekhulu degrees Celsius. Kodwa xa amaqondo obushushu kusithwa 0 degrees ulwelo uguqulwe ngumkhenkce.

Okubangel 'umdla kukuba, ukuncipha womoya ebangela ukwahluka kula parameters - amanzi amathumba kwiqondo eliphantsi.

Le conductivity thermal amanzi nama-0,58 W / (m * K). Enye into ebalulekileyo - kwalo phezulu kwempixano ngaphezulu, apho phantse kulingane inani engqinelanayo mercury.

Iimpawu ezizodwa emzimbeni amanzi

Njengoko sele kukhankanyiwe, kuba amanzi eqinisekisa ubukho okuqhelekileyo umhlaba, echaphazela imozulu kunye nomsebenzi ebalulekileyo eziphilayo. Kodwa ngokwenene le nto yahlukile. Kuyinto ezi propati emangalisayo amanzi zinika ubomi.

Ngokomzekelo, lexinene ice namanzi. Kwiimeko ezininzi, ezi molekyuli izinto neGauteng zilungiswe kufutshane omnye komnye, isakhiwo liba luthe compact ngakumbi. Kodwa ngamanzi, eli cebo akusebenzi. Kuba okokuqala kule ndawo emangalisayo iye yachazwa yi UGalileo.

Ukuba chu ukuthoba iqondo lobushushu esweni qhwa amanzi, i-scheme lokuqala umgangatho kakhulu - iziyobisi ziya kuba luthe compact ngakumbi. Utshintsho zenzeka emva ubushushu ifikelela 4 ° C. Xa kuba lula ngequbuliso loo manzi salathisi. Yiloo nto umkhenkce ndiyihlanganise ndiyidadise phezu kwamanzi, kodwa akazange ukutshona. Hi ndlela leyi, lo msebenzi osemqoka iqinisekisa ukusinda enezityalo nezilwanyana zasemanzini - amanzi azifane ngumkhenkce ngokupheleleyo, ukusindisa ubomi nabemi bazo.

Koko, ngexesha qhwa ukwimo iyavuleka nge-9%. Olu phawu kwamanzi kubangela umhlwa yamatye zendalo. Kwelinye icala, umbhobho wamanzi ke ngoko kuyaphula phezu kobubi ngequbuliso.

Kodwa oku zonke iipropati umdla amanzi. Enye inkalo unique ngayo - into anomalously umthamo omkhulu ubushushu. Umzekelo, umlinganiselo ubushushu ezifunekayo ubilisa yegram enye amanzi isidanga mnye, ngokwaneleyo ukuba shushu-10 g sobhedu okanye nentsimbi 9 g.

Zonke elwandle - ubushushu womhlaba, smoothes ukuhla kwamaqondo obushushu, zombini diurnal nezonyaka. Ke kaloku, iimpawu ezifanayo kwaye wasinika kunye nomphunga wamanzi equlethwe emoyeni. Yinto akukho mfihlelo intlango uphawuleka utshintsho obushushu ngesiquphe - imini ishushu kakhulu yaye kubanda kakhulu ebusuku. Le ezinxulumene ixesha umoya owomileyo kunye nokungabikho imali efunekayo umphunga wamanzi.
