Madzi amasanduka nthunzi ku 100oC. Sublimation - Izi ndizosowa kwambiri kusintha kwa thupi zomwe zimachokera ku chinthu chomwe chikudutsa kutentha kwakukulu kusintha. Izi zimasintha cholimba kukhala gasi. Chitsanzo chimodzi cha zimenezi ndi pamene madzi oundana owuma (ozizira mpweya wa carbon dioxide (chifukwa chake olimba)) amakumana ndi kutentha kwa chipinda.

Mofananamo, mungafunse, kodi ayezi wouma ndi mankhwala kapena kusintha kwa thupi?

Izi ziyenera kukhala a kusintha kwa mankhwala, chifukwa chinthu chatsopano-"chifunga" -mawonekedwe. Kwenikweni, madzi oundana owuma akudutsa a kusintha kwa thupi pamene sublimates kuchokera cholimba kuti mpweya boma popanda choyamba kusungunuka kukhala madzi. Mpweya wofanana wa carbon dioxide udakalipo, umangodutsa gawo limodzi kusintha kukhala mpweya wopanda mtundu.
