Sublimation yog tus txheej txheem los ntawm qhov uas khov kho yam khoom hloov ncaj qha rau hauv vapors lossis gaseous lub xeev tsis dhau los ntawm lub xeev ua kua.

Ntawm no, Gas tuaj yeem hloov ncaj qha mus rau khoom?

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.

Ib sab saum toj no, qhov hloov pauv theem twg yog txheej txheem exothermic? Fusion, vaporization, thiab sublimation yog endothermic cov txheej txheem, whereas khov, condensation , thiab deposition yog exothermic txheej txheem. Cov kev hloov ntawm lub xeev yog cov piv txwv ntawm kev hloov theem, los yog theem hloov. Txhua theem kev hloov pauv yog nrog los ntawm kev hloov pauv ntawm lub zog ntawm lub cev.

Kuj Paub, nws hu ua dab tsi thaum lub roj hloov mus rau hauv cov khoom?

Deposition yog theem kev hloov nyob rau hauv uas gas hloov rau hauv cov khoom tsis dhau los ntawm cov kua theem. Qhov rov qab ntawm deposition yog sublimation thiab li no qee zaum deposition hu ua desublimation.

Vim li cas cov khoom tuaj yeem ncaj qha evaporate?

Qee qhov muaj zog ntau dua nyob rau saum npoo ntawm cov kua ua tau txav ceev kom khiav tawm ntawm lub zog txaus nyiam tuav cov kua ua ke. Lawv evaporate . Raws li cov molecules nyob rau hauv dej jostle nrog ib leeg, tshiab molecules yuav tau txais lub zog txaus kom khiav tawm ntawm qhov chaw.
