Lub sij hawm Tyndall cov nyhuv feem ntau yog siv nrog cov nyhuv ntawm lub teeb tawg ntawm cov khoom hauv cov tshuab colloid, piv txwv li, tshem tawm lossis emulsions. … Txij li thaum colloids muaj cov khoom nyob rau hauv lawv uas tawg lub teeb dhau los, lawv qhia Tyndall cuam tshuam.
Ua emulsions tawg lub teeb?
Cov khoom nruab nrab nruab nrab no loj txaus rau tawg lub teeb, tab sis me me kom nyob twj ywm hauv cov kua. … Emulsions yog immiscible (tsis muaj peev xwm sib tov) colloidal suspensions ntawm ib cov kua hauv lwm cov kua. Emulsions yuav cais mus rau hauv lawv tus kheej cov khoom yog tso cai zaum ntev txaus.
Puas emulsion qhia Brownian motion?
Emulsions kuj qhia Brownian zog thiab Tyndall nyhuv. Lus Qhia: Lub sij hawm 'emulsion' nyob rau hauv chemistry nto yog siv los sawv cev rau colloidal dispersion nyob rau hauv uas ob theem dispersed thiab dispersion nruab nrab yog kua. Ob lub kua uas koom nrog yog lwm yam immiscible.
Cov kua dej twg yuav ua rau pom cov nyhuv Tyndall?
-Qhov tawg ntawm lub teeb los ntawm cov tshuaj colloidal qhia peb tias cov khoom colloidal loj dua li cov khoom ntawm cov tshuaj muaj tseeb. - Peb tuaj yeem pom tias cov kev xaiv raug yog (B) thiab (D), mis nyuj thiab hmoov txhuv nplej siabyog cov colloids, yog li cov no yuav qhia cov nyhuv tyndall.
Puas Lyophobic qhia Tyndall effect?
Tyndall effect is shown by lyophobic (txhais tau tias ua kua dej)… qhov no yog vimlawv nyob rau hauv lawv cov lus tsa suab yog tas li ntaus los ntawm cov khoom ntawm cov kua, li no peb saib ib tug random motion nyob rau hauv lub lyophobic colloids…..

Leej twg piav qhia qhov tshwm sim ntawm cov nyhuv photoelectric?
Einstein thaum kawg tau muab khoom plig Nobel rau Physics hauv xyoo 1921 rau kev piav qhia txog cov nyhuv photoelectric. Leej twg pom cov nyhuv photoelectric? Qhov no tau los ua lub npe hu ua photoelectric effect, thiab nws yuav nkag siab hauv xyoo 1905 los ntawm tus kws tshawb fawb hluas hu ua Albert Einstein.
Puas tsis yog hlau qhia cov nyhuv photoelectric?
Kev piav qhia: Cov nyhuv Photoelectric tsuas yog rau thawj pab pawg txawm tias tsis yog tag nrho cov ntsiab lus.Yog li nws tsis pom los ntawm cov hlau tsis yog hlau kuj . Nyob rau hauv cov nyhuv no valence electrons ejected los ntawm photometal thaum lub teeb yog absorbed los ntawm cov hlau.
Leej twg piav qhia txog cov nyhuv photoelectric ua ntej?
Qhov no tau paub tias yog cov nyhuv photoelectric, thiab nws yuav nkag siab hauv xyoo 1905 los ntawm tus kws tshawb fawb hluas hu ua Albert Einstein. Einstein txoj kev txaus siab rau kev tshawb fawb tau pib thaum nws muaj 4 lossis 5 xyoos, thiab thawj zaug pom lub tshuab sib nqus.
Nyob rau hauv tyndall nyhuv cov colloidally suspended hais?
In Tyndall effect cov colloidally suspended particles taug txoj kev ntawm lub teeb muaj zog ntawm lub teeb vim yog tawg ntawm lub teeblos ntawm cov khoom colloidal. Puas tshem tawm cov khoom ua kom pom cov nyhuv Tyndall? Tyndall cov nyhuv yog qhov pom ntawm lub teeb tawg ntawm cov khoom ntawm qhov ntev ntawm colloidal.
Puas tus number case qhia tyndall effect?
Raws li txhua qhov kev daws teeb meem colloidal qhia tyndall effect number case yog colloidal vim nws cov khoom loj thiab tuaj yeem tso lub teeb hla nws. Li no tyndall effect tuaj yeem pom. Puas tus number case qhia Tyndall nyhuv dej?
