Qhov no yuav tsum yog cov tshuaj hloov pauv, vim tias cov tshuaj tshiab-"fog"-forms." Qhov tseeb, cov dej khov qhuav tau hloov pauv lub cev thaum nws sublimates los ntawm cov khoom mus rau lub xeev gaseous yam tsis tau yaj ua ntejrau hauv cov kua. Tib cov pa roj carbon dioxide tseem nyob tam sim no, nws nyuam qhuav dhau ib theem hloov mus ua cov pa tsis muaj xim.
Puas yog cov dej khov qhuav sublimation yog cov khoom siv tshuaj?
Sublimation yog qhov hloov pauv lub cev. Thaum cov khoom siv sublimes, nws hloov los ntawm cov khoom mus rau ib qho roj yam tsis tau mus rau theem ua kua. Qhov no tsis ua rau muaj kev hloov tshuaj lom neeg, txawm li cas los xij. Cov dej khov qhuav yog carbon dioxide nyob rau theem khoom.
Puas yog sublimation hloov pauv lub cev lossis tshuaj lom neeg?
Lub sij hawm sublimation yog hais txog lub cev hloov pauv ntawm lub xeevthiab tsis yog siv los piav qhia txog kev hloov pauv ntawm cov khoom rau cov roj hauv cov tshuaj tiv thaiv. Piv txwv li, kev sib cais ntawm cov cua sov ntawm cov khoom ammonium chloride rau hauv hydrogen chloride thiab ammonia tsis yog sublimation tab sis muaj tshuaj tiv thaiv.
Puas yog vaporization hloov tshuaj?
Kev piav qhia: Nws yog qhov hloov pauv ntawm lub cev vim tias nws mus los ntawm cov kua theem mus rau theem roj. Nws tsis yog tshuaj hloov pauvvim nws tseem ua los ntawm ob lub atom hydrogen thiab ib qho oxygen atom.
Yuav ua li cas rau cov dej khov qhuav thaum nws Sublimes?
Thaum lub zog xa mus rau cov dej khov qhuav, cov khoom carbon dioxide tsis yaj rau cov kua carbon dioxide. Hloov chaw, cov khoom hloov pauv ncaj qha rau roj txheej txheem no hu ua sublimation. Sublimation tshwm sim thaum cov molecules ntawm cov khoom txav nrawm txaus los kov yeej cov kev nyiam los ntawm lwm cov molecules thiab dhau los ua roj.
