- Mehlala ho tloha ho tiileng ho isa ho khase (sublimation)
- Mehlala ho tloha Gaseous ho Solid (Reverse Sublimation)
Taba ke ntho e ngoe le e ngoe e nang le boima le 'mele ebile e lula sebakeng. E ka fumanoa libakeng tse tharo: metsi, a tiileng ebile a na le moea o mongata. Puso ka 'ngoe e na le litšobotsi tse bonahalang.
Ha taba e pepesetsoa liphetoho tse kholo khatello kapa mocheso, e ka fetoha maemong a eona (ho tloha ho tiileng ho isa ho khase, ho tloha mokelikeli ho isa ho o tiileng, ho tloha ho khase ho ea ho mokelikeli le ka tsela e ts'oanang). Maemong ohle moo phetoho ea boemo ba taba e etsahalang, ha e fetohe ntho e ngoe empa e fetola chebahalo ea eona ntle le ho fetola lik'hemik'hale tsa eona.
Liketsahalo tse etsahalang ha taba e tloha boemong bo tiileng (e na le sebopeho se hlalositsoeng) ho ea boemong bo nang le moea (ha e na bophahamo ba modumo kapa sebopeho mme e hola ka bolokolohi), ka lehlakoreng le leng, ke:
- Sublimation. Phenomenon eo ka eona taba e tsoang boemong bo tiileng ho ea boemong ba gaseous ntle le ho feta maemong a mokelikeli. Mohlala: li-mothball tse ntseng li senyeha butle-butle ho tloha leqhoeng ho ea leqhoeng le ommeng (carbon dioxide e ommeng). Ntho e monya matla a feteletseng tikolohong ea eona.
- Khutlisa deposition kapa sublimation. Phenomenon eo ka eona taba e tsoang ho gaseous ho ea state e tiileng. Li-gaseous particles li khomarela ho feta kamoo li tloaetseng ho ba teng ebe li ea ka kotlolloho boemong bo tiileng ntle le ho feta maemong a metsi. Mofuta ona oa phetoho hangata o fanoa ke ho theoha ha mocheso le tlasa maemo a itseng a khatello. Mohlala: sebopeho sa lehloa kapa serameho. Ts'ebetso ena e ntša matla.
Leha ho le joalo, maemong a mangata elemente e tloha boemong ba likhase ho ea boemong ba mokelikeli (condensation) ebe e tloha moo e ea boemong bo tiileng. Phetoho ho tloha ho gase ho ea solid (le ka tsela e fapaneng) e etsahala tlasa maemo a ikhethileng.

Mehlala ho tloha ho tiileng ho isa ho khase (sublimation)
- Sebabole. Sublimates maemong a phahameng a likhase tse nang le chefo e phahameng.
- Iodine e tiileng. Kamora sublimation e fetoha khase e 'mala oa bopherese.
- Arsenic. Ha khatello ea sepakapaka e fihla ho 613 ° C.
- Leqhoa kapa lehloa E ka theolela maemong a leholimo a ka tlase ho 0 ° C.
- Benzoic acid Sublimates kaholimo ho 390 ° C.
- Khamphor. Sublimates ka mocheso o itseng.
- Letlapa le nkhang hamonate. E fokotsa butle-butle joaloka naphthalene.
- Mehlala e meng ho: Sublimation
Mehlala ho tloha Gaseous ho Solid (Reverse Sublimation)
- Soot. Boemong bo chesang le bo nang le moea o mongata, ea phahama, e kopana le marako a chomela ebe ea tiisa.
- Lehloa. Mocheso o tlase o etsa hore mouoane oa metsi marung o fetohe lehloa.
- Makhasi a iodine litareng. Ha ho futhumetse, ho hlahisoa mouoane, o kopanang le ntho e batang e fetoloang hape ho ba likristale tsa iodine.
