Sodium Chloride yog cov khoom ionic thiab muaj cov ntsiab lus melting siab thiab kub kub. Yog li nws tsis tuaj yeem hloov pauv hauv vapor theem tsuas yog ntawm cov roj siab li no nws tsis tuaj yeem sublime. Ammonium chloride, khoom thiab iodine undergo sublimation uas ntawm cua sov yam tsis tuaj hauv lub xeev ua kua ncaj qha hloov mus rau lub xeev gaseous.
Nh4cl puas yog sublimate?
Ammonium chloride zoo li sublime thaum cua sov tab sis ua tau decomposes rau hauv ammonia thiab hydrogen chloride gas.
Puas yog nacl yog sublimation tshuaj?
Sodium chloride yog cov khoom ionic thiab muaj cov ntsiab lus kub yaj thiab kub kub. Yog li ntawd, nws tsis tuaj yeem hloov pauv hauv vapor theem tsuas yog ntawm atmospheric siab yog li nws tsis tuaj yeem sublimate.
Yuav ua li cas yog sublimative tshuaj?
Sublimation yog qhov hloov pauv ntawm lub xeev los ntawm cov khoom mus rau cov roj yam tsis tau dhau los ntawm lub xeev cov kua. "Dry ice," los yog cov pa roj carbon dioxide, yog ib yam khoom uas sublimes ntawm atmospheric pressures. Cov dej khov qhuav yog txias heev (-78 ° C) thiab yog li siv los ua cov khoom txias rau cov khoom xws li ice cream uas yuav tsum tau khov thaum xa khoom.
Cov tshuaj hauv qab no twg tuaj yeem ua tau zoo?
Cov tshuaj uas paub zoo uas yooj yim nkag tau muaj xws li iodine(pom hauv qab), dej khov qhuav (qhia hauv qab), menthol, thiab camphor. Sublimation yog qee zaus siv hauv chav kuaj ua ib txoj hauv kev rau kev ntxuav cov khib nyiab, piv txwv li, nrog caffeine.
