Hauv qee qhov xwm txheej, gas tau hloov ncaj qha hauv a khov kho . Cov txheej txheem no hu ua deposition. Dej vapor rau dej khov - Dej vapor transforms ncaj qha rau hauv dej khov yam tsis tau ua kua, ib txheej txheem uas feem ntau tshwm sim ntawm qhov rais thaum lub caij ntuj no.

Ua li no, txheej txheem hu ua dab tsi thaum lub roj hloov ncaj qha mus rau ib qho khoom?

Deposition yog theem hloov nyob rau hauv uas gas transforms rau hauv khov kho tsis dhau los ntawm cov kua theem. Deposition yog ib qho thermodynamic txheej txheem . Qhov rov qab ntawm deposition yog sublimation thiab li no qee zaum deposition yog hu ua desublimation. Qhov no ua rau dej vapor rau hloov ncaj qha hauv a khov kho.

Ib yam li ntawd, cov khoom puas tuaj yeem hloov mus rau hauv cov roj yam tsis tau ua kua? Qee yam khoom ua tau txawm ua pa tsis muaj roj ua ntej ua kua ; qhov no yog hu ua "sublimation". Piv txwv li, dej khov hauv lub freezer maj mam ploj mus, vim nws yog subliming ua gas.

Nyob rau hauv no hais txog, dab tsi tig los ntawm ib tug khoom mus rau ib tug roj?

Khoom rau Gas thiab Rov qab mus rau a Khoom Nws yog txheej txheem hu ua sublimation. Qhov yooj yim piv txwv ntawm sublimation tej zaum yuav yog cov dej khov qhuav. Dej khov qhuav yog khov kho carbon dioxide (CO2). Amazingly, thaum koj tso dej khov qhuav tawm hauv ib chav, nws tsuas yog tig hauv a gas.

Ib qho piv txwv ntawm cov roj rau khoom yog dab tsi?

Hauv qee qhov xwm txheej, roj tuaj yeem hloov ncaj qha mus rau hauv cov khoom. Cov txheej txheem no hu ua deposition. Dej vapor rau ice - Dej vapor transforms ncaj qha mus rau hauv dej khov yam tsis tau ua kua, ib tug txheej txheem uas feem ntau tshwm sim ntawm lub qhov rais thaum lub caij ntuj no lub hlis.
