Ukuhwamuka futhi ukufingqa

Kulesi sihloko, sizofunda embule incazelo kwemiqondo efana "ukuhwamuka" futhi "ukufingqa".

Vaporisation libhekene inguquko kusuka into ewuketshezi esimweni gaseous. Lokhu kungenziwa izindlela ezimbili: by abilayo noma ukuhwamuka indlela.

Ukuhwamuka ngokuthi inqubo vaporization, ebanjwa ebusweni ketshezi ketshezi. Okulandelayo kuchaza kabanzi ngemininingwane, indlela ukuhwamuka futhi ukufingqa, isb inqubo reverse - ukubuya kwama-molecule e ketshezi. Inqubo ukuhwamuka Kwenziwa kanje: ngenxa yokuthi ukuthi molecule iyiphi into esimweni liquid ngokuqhubekayo ezihambayo nemiyalezo, futhi aphenduka ngejubane elingafani. Phakathi kwabo kukhona sisakhangana ngawo abakwazi fly ukuphuma, kodwa uma into ebusweni ngabe molecule nge high energy kinetic, ngeke unqobe amandla Luhambo phakathi molecule uyosuka ketshezi. Inqubo efanayo kuzophindwa namanye ama-molecule. Ukuthatha off phandle molecule akha umusi ngenhla ketshezi. Lona ukuhwamuka.

Ngenxa ketshezi kusukela ukuhwamuka sasikhipha molecule kokuba kufike komkhulu wabo velocity, isilinganiso Inkomba energy kinetic zishintshe, okuyinto asele ketshezi kuyinto phezu ukwehla. Ngenxa yalokho, izinga lokushisa ketshezi ahwamukayo kuyehla, futhi selehlile. Ngesikhathi esifanayo, siyazi ukuthi amanzi isikhathi eside njengabasodwendweni shabalala ingilazi, kodwa ongakayeki selehlile ngokuqhubekayo kuze eqina ngenxa yamakhaza. Kungani? Lonke iphuzu yamanzi exchange ukushisa ne izikhatha zomoya oshisayo ozungezayo ingilazi.

Izinga ukuhwamuka lincike ohlotsheni oluthile loketshezi, izinga lokushisa kwaso, ndawo ubuso ketshezi ketshezi, ku khona izidakamizwa liquid ebusweni umoya.

Cooling ketshezi isimo uketshezi ukuhwamuka ngaphansi kakhulu ngaphezulu okusheshayo ukuhwamuka inqubo. Izinto ukuthi shabalala ngokushesha, elisetshenziswa zobunjiniyela. Ukubandisa ketshezi ngesikhathi ukuhwamuka lisetshenzisiwe nangokuqondene amadivayisi ulinganise nomswakama.

Ngokuhlolwa ilila kungaba azimisele ukuthi izinga ukuhwamuka kuzokhulisa nge okwandisa izinga lokushisa we ketshezi uketshezi, kanye wakhona ukwanda we khulula surface area.

Ukuhwamuka futhi ukufingqa izinqubo okuphambene. Siye safunda ukuthi lokhu ukuhwamuka, kodwa manje awubheke ukuthi ukufingqa. Lolu ketshezi iyasha ngokushesha khona umoya, kodwa kungani? Lokhu kungenxa yokuthi phakathi ukuhwamuka Kwenziwa futhi inqubo okuphambene, ngokuthi "ukufingqa". It kuvela ngenxa yokuthi abanye yezinhlayiya umusi, ihamba phezu into ewuketshezi emuva ku-ke futhi. Umoya uthwala molecule fly out emajukujukwini, singavumeli ukuba ubuye.

Ukufingqa amanzi umusi kwenzeka icala lapho akusiyo nabo ketshezi ketshezi. Cloud kumiswa kuyinqubo ukufingqa lapho ububi ngentukuthelo ukhuphuka uvela molecule phansi zib amanzi amancane lehla izingqimba abandayo asemkhathini e. Imvula namazolo - liphinde phetho ukufingqa amanzi umusi in imvelo.

Liquid-selehlile ngesikhathi ukuhwamuka, ekubeni imvelo esibandayo, uqala ukuba afeze ukumuncwa yayo amandla. Inani amandla okubanjwa ngokuthi "ukushisa esicashile yokuhwamuka."

A Kwenzeka okuphambene lapho ukufingqa: amandla ukhululeka imvelo, ngaleyo ndlela kwande lokushisa yayo ipharamitha. Kukhona futhi izinhlobo ezimbili zezinkantolo ukufingqa: ifilimu uconsisele. Kumiswa ifilimu is phezu wetted futhi ephelezelwa ukubukeka ifilimu. On surface engasekelwa wetted, le condensate kwakhiwa droplet.

Ukuhwamuka futhi ukufingqa zisetshenziswa practice ngesikhathi ukusebenza umshini ifriji.
