sib tov tuaj yeem sib cais siv ntau txoj kev sib cais xws li pom, cais funnel, sublimation, yooj yim distillation thiab ntawv chromatography . Cov txheej txheem tau hais los saum no yog txhua txoj hauv kev ntawm lub cev.
Ib yam li ntawd, 5 txoj hauv kev los cais qhov sib tov yog dab tsi?
Hauv qab no yog qee txoj hauv kev sib cais:
- Ntawv Chromatography. Txoj kev no feem ntau siv hauv kev lag luam khoom noj.
- Lim. Qhov no yog ib txoj kev ntau dua ntawm kev sib cais cov khoom insoluble los ntawm cov kua.
- Evaporation.
- Yooj yim distillation.
- Fractional distillation.
Tsis tas li ntawd, 8 txoj hauv kev ntawm kev sib cais sib xyaw yog dab tsi? Cov ntsiab lus hauv cov teeb no (8)
- Distillation. sib cais los ntawm boiling point sib txawv.
- Floatation. kev sib cais ntawm cov khib nyiab los ntawm qhov sib txawv.
- Chromatography. sib cais los ntawm sab hauv molecular attractions.
- Magnetism.
- Lim.
- Kev rho tawm.
- Crystallization.
- Mechanical Separation.
Ib yam 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.

Qhov txawv ntawm kev sib txuas thiab kev sib cais yog dab tsi?
Thaum ob nqe lus ua ke nrog 'thiab,' koj muaj kev sib txuas. Rau kev sib txuas, ob nqe lus yuav tsum muaj tseeb rau cov lus sib xyaw kom muaj tseeb. Thaum koj ob nqe lus ua ke nrog 'los yog' koj muaj kev tsis sib haum xeeb
Dab tsi yog lub tswv yim ntawm kev txhawb nqa ntawm kev sib cais ntawm kev sib deev?
Kev txhawb zog yog cov txheej txheem los ntawm kev xaiv ntuj tsim kom muaj kev sib cais ntawm kev sib deev. Kev txhawb zog tuaj yeem tshwm sim raws li hauv qab no: Thaum ob pawg neeg uas tau khaws cia sib nrug, rov qab los rau hauv kev sib cuag, qhov kev sib cais ntawm cov menyuam yaus yuav ua tiav lossis tsis tiav. Yog tias nws ua tiav, speciation tau tshwm sim
Yuav ua li cas koj cais ib tug sib tov ntawm pigments los ntawm ib tug number case cartridge?
Txhawm rau cais qhov sib xyaw ntawm cov xim uas yog ob lub dyes, daim ntawv chromatography yog siv. Ib feem me me ntawm qhov sib tov yog muab tso rau hauv cov khoom siv absorbent, ib daim ntawv lim, nrog cov kuab tshuaj. Ob lub dyes yuav txav mus rau nyias thiab tus number case yuav sib cais rau hauv nws cov khoom ntshiab

Albert Einstein txoj kev xav ntawm kev txheeb ze hloov txoj cai ntawm kev txuag hluav taws xob li cas? Thaum ib yam khoom lossis lub cev ua haujlwm rau lwm yam khoom, qee qhov ntawm nws lub zog raug xa mus rau qhov khoom ntawd
Dab tsi yog qhov kev sib txuas ntawm kev txheeb cais hauv qhov tshwm sim?
Qhov yuav tshwm sim thiab kev txheeb cais yog cov cheeb tsam ntawm kev ua lej uas cuam tshuam lawv tus kheej nrog kev txheeb xyuas qhov txheeb ze ntawm cov xwm txheej. Qhov tshwm sim muaj feem cuam tshuam nrog kev kwv yees qhov yuav tshwm sim ntawm cov xwm txheej yav tom ntej, thaum cov txheeb cais suav nrog kev txheeb xyuas qhov zaus ntawm cov xwm txheej yav dhau los
