Evaporation yog a cov txheej txheem siv cais tawm homogeneous sib tov qhov twg muaj ib los yog ntau ntsev yaj. Cov txoj kev tshem tawm cov khoom ua kua los ntawm cov khoom siv. Cov txheej txheem feem ntau suav nrog cua sov cov sib tov kom txog thaum tsis muaj kua ntxiv.

Kev sib raug zoo, koj yuav ua li cas thiaj paub siv cov txheej txheem sib cais twg?

Cov ntsiab lus

  1. Kev sib xyaw ua ke tuaj yeem sib cais siv ntau hom kev kawm.
  2. Chromatography suav nrog kev sib cais hnyav ntawm cov khoom nruab nrab.
  3. Distillation siv qhov zoo ntawm qhov sib txawv ntawm cov ntsiab lus kub.
  4. Evaporation tshem tawm cov kua los ntawm kev daws kom tawm hauv cov khoom siv.
  5. Lim cais cov khib nyiab ntawm qhov sib txawv.

Ib tug kuj yuav nug, dab tsi yog tsib txoj kev sib cais? Ntau hom kev sib cais yog:

  • Crystallization.
  • Lim.
  • Decantation.
  • Sublimation.
  • Evaporation.
  • Yooj yim distillation.
  • Fractional distillation.
  • Chromatography.

Tsuas yog li ntawd, 7 txoj hauv kev los cais cov sib tov yog dab tsi?

Txheeb xyuas txoj hauv kev xaiv tes, Threshing, Winnowing, Sieving, Sib nqus Attraction, Sublimation, Evaporation , Crystallization, Sedimentation & Decantation, Chaw thau khoom, Lim , Distillation , Centrifugation, thiab ntawv Chromatography tuaj yeem siv tau hauv lub neej txhua hnub.

Dab tsi yog 10 txoj hauv kev ntawm kev sib cais sib xyaw?

Qee txoj hauv kev sib cais cov tshuaj los yog sib tov yog:

  • Kev xaiv tes.
  • Khaub ncaws.
  • Winnowing.
  • Sieving.
  • Evaporation.
  • Distillation.
  • Lim los yog Sedimentation.
  • Sib cais Funnel.
