Supersaturated daws kev taw qhia
Hauv qee qhov xwm txheej, qhov me dua qhov siv lead ua, ntau dua kev solubility. Yog li no, thaum kev tov yog evaporated ntawm qhov kub tsis tu ncua, qhov siab ntawm cov solute zuj zus. Thaum lub saturation concentration ntawm qhov zoo tib yam solute siv lead ua tau mus txog, lub solute ntawm lub me me siv lead ua tseem tsis tau mus txog rau lub xeev saturation, thiab lub nucleus yog qhov tseem ceeb ntawm cov siv lead ua loj hlob nyuaj rau los nag. Txhawm rau kom lub ntsej muag siv lead ua los ua kom muaj kev tsim hluav taws xob, nws yog qhov yuav tsum tau txuas ntxiv txhawm rau kev daws teeb meem rau qee qhov kev kawm dhau los ua ntej cov kua siv lead ua kom tsis tu ncua. Raws li cov theem ua kom sib npaug, yuav tsum muaj ib txoj kev daws teeb meem uas cov muaju hauv dej tab sis tsis yog nag lossis daus, uas yog hu ua cov tshuaj supersaturated.
