Sib cais cov khib nyiab los ntawm cov kua - evaporation Evaporation yog siv los cais cov khoom soluble solid los ntawm cov kua. Piv txwv li, tooj liab sulfate yog soluble nyob rau hauv dej - nws cov crystals yaj nyob rau hauv dej los tsim tooj liab sulfate tov. Thaum lub sij hawm evaporation, cov dej evaporates tawm ntawm cov khoom tooj liab sulfate crystals qab.
YPuas evaporation homogeneous los yog heterogeneous?
Evaporation yog ib txoj kev siv los cais tawm homogeneous mixs uas muaj ib lossis ntau dua cov ntsev yaj. Cov txheej txheem tsav tawm cov khoom ua kua los ntawm cov khoom siv. Cov txheej txheem feem ntau suav nrog cua sov qhov sib tov kom txog thaum tsis muaj kua ntxiv lawm.
Puas evaporation yog sib tov ntawm cov khoom?
Sib cais los ntawm evaporation: Kev hloov cov kua rau hauv vapors yog hu ua evaporation. Evaporation yog siv los cais cov khoom uas tau yaj hauv dej (los yog lwm yam kua). Cov khoom uas yaj tau raug tso tseg raws li cov khoom seem thaum tag nrho cov dej (los yog kua) tau evaporated.
Dab tsi yog cov khoom seem tom qab evaporation?
Thaum cov tshuaj tau rhuab, cov kuab tshuaj evaporates, tawm hauv qab cov khoom tawg ua residue. Thaum cov tshuaj uas muaj cov kuab tshuaj yaj yog rhuab, cov kuab tshuaj yuav evaporate. Tsuas yog tus solute yuav nyob twj ywm hauv lub tais evaporating. Piv txwv li: dej thiab ntsev.
Puas evaporation cais insoluble solids?
Evaporation yog siv los ua cais cov khoom tsis sib haum los ntawm cov kua.
