Thaum evaporation, nquag molecules tawm ntawm cov kua theem, uas txo qis lub zog nruab nrab ntawm cov kua molecules. Cov kua molecules uas tseem tshuav tuaj yeem nqus tau lub zog ntawm lawv ib puag ncig.
Yuav ua li cas thaum cov kua evaporation?
Evaporation tshwm sim thaumcov kua dej dhau los ua roj. Thaum dej sov, nws evaporates. Cov molecules txav thiab vibrate sai heev uas lawv khiav mus rau hauv cov huab cua raws li molecules ntawm dej vapor.
Yuav ua li cas rau qhov kub ntawm cov kua thaum nws evaporates?
Evaporation yog hom vaporization ntawm cov kua uas tsuas yog tshwm sim ntawm cov kua dej. … Raws li cov molecules khiav nrawm dua, cov molecules uas tseem tshuav muaj lub zog nruab nrab qis qis, thiab qhov kub ntawm cov kua txo qis. Qhov tshwm sim no tseem hu ua evaporative txias.
Thaum evaporation tshwm sim cov kua uas seem yog txias dua vim?
Evaporation ua rau txias vim txheej txheem yuav tsum muaj lub zog cua sov. Lub zog raug tshem tawm los ntawm cov molecules thaum lawv hloov los ntawm cov kua mus rau hauv cov pa, thiab qhov no ua rau txias rau ntawm qhov chaw qub.
evaporation Nws tshwm sim qhov twg hauv cov kua?
Evaporation tshwm sim thaum cov kua hloov mus ua roj. Nws tuaj yeem pom tau yooj yim thaum nag los nag "poob" rau hnub kub lossis thaum cov khaub ncaws ntub dej qhuav hauv lub hnub. Hauv cov piv txwv no, cov dej ua kua tsis tau ploj mus - nws yogevaporating rau hauv cov pa roj, hu ua dej vapor. Evaporation tshwm sim nyob rau hauv lub ntiaj teb no.
