Yuav ua li cas mus rau saturation concentration thaum a daws temp yog nce. Yuav ua li cas as a daws yog cua sov ? Yog koj kub ib yam khoom ntau koj taub hau nws ntau qab zib yaj tam sim no lub solubility yuav mus siab dua, thaum twg cua sov vim nws yuav siv sij hawm ntau rau cov khoom kom saturated. Kuj khov.
Ua kom pom qhov no, yuav ua li cas rau qhov saturation concentration thaum cov tshuaj rhuab?
Test rau Saturation Txawm li cas los xij, yog tias ib qho tshwj xeeb saturated tshuaj ntawm qhov kub thiab txias cua sov mus rau qhov kub thiab txias, ces nws yuav unsaturated. Qhov no tshwm sim vim yog thov ntau kub , solubility ntawm solute nce. Yog li, koj tuaj yeem yaj ntau dua ntawm solute los ntawm kev nce qhov kub ntawm qhov daws.
Ib sab saum toj no, yuav ua li cas tshwm sim raws li ib tug tov yog rhuab Vim li cas qhov no tshwm sim? Teb: Yog saturated tov yog rhuab tus daws ua unsaturated vim solubility ncaj qha nyob ntawm qhov kub thiab txias, yog li ntawm cov cua sov solubility ntawm cov daws nce thiab nws ua unsaturated los yog nyob rau hauv lwm yam lus cov daws tam sim no muaj peev xwm coj qee qhov kev daws teeb meem ntxiv rau hauv nws.
Ib yam li ntawd, qhov ntsuas kub puas cuam tshuam rau qhov concentration ntawm cov tshuaj?
Molarity yog moles ntawm solute ib liter ntawm daws . Dej nthuav raws li cov kub nce, yog li lub ntim ntawm cov daws kuj nce. Koj muaj tib tus lej ntawm moles hauv ntau litres, yog li cov molarity tsawg dua kub.
Thaum tshav kub kub cuam tshuam li cas rau solubility?
Rau ntau cov khib nyiab yaj hauv cov kua dej, cov solubility nce nrog kub. Qhov nce hauv lub zog kinetic uas los nrog qhov kub siab dua tso cai rau cov kuab tshuaj molecules ua kom zoo dua sib cais cov kuab tshuaj molecules uas tau tuav ua ke los ntawm kev sib cuam tshuam.

Yuav ua li cas tshwm sim rau tam sim no nyob rau hauv ib tug parallel circuits thaum ntxiv qhov muag teev?
Raws li ntau qhov muag tau ntxiv, qhov tam sim no nce. Raws li ntau resistors ntxiv nyob rau hauv parallel, tag nrho tam sim no lub zog nce. Yog li ntawd, tag nrho cov tsis kam ntawm Circuit Court yuav tsum tau txo. Qhov tam sim no nyob rau hauv txhua lub teeb yog tib yam vim hais tias tag nrho cov qhov muag teev glowed nrog tib brightness
Yuav ua li cas tshwm sim thaum Orthoboric acid yog rhuab tshaj 370k?
Ntawm cov cua kub orthoboric acid saum toj no 370k cov ntaub ntawv metabolic, HBO2, uas ntawm cov cua kub ntxiv yields boric oxide B2O3
Tus qauv yuav pab nrhiav qhov tshwm sim ntawm qhov kev tshwm sim sib xyaw li cas?
Lub ntsiab lus ntawm Qhov Muaj Peev Xwm Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej yog ib qho uas muaj ntau tshaj li qhov ua tau. Kev txiav txim siab qhov yuav tshwm sim ntawm qhov kev tshwm sim sib xyaw suav nrog kev nrhiav cov lej ntawm qhov tshwm sim ntawm tus kheej cov xwm txheej thiab, yog tias tsim nyog, tshem tawm qhov muaj feem sib tshooj
Vim li cas nws tseem ceeb uas yuav tsum rov ua qhov kev sim thiab sim cov kev xav hauv ntau txoj kev?
Nws yog ib qho tseem ceeb rau cov kws tshawb fawb kom rov sim dua thaum ua qhov kev sim vim tias qhov kev txiav txim siab yuav tsum raug lees paub. Muaj tseeb vim tias cov txiaj ntsig ntawm txhua qhov kev xeem yuav tsum zoo sib xws. Lwm cov kws tshawb fawb yuav tsum tuaj yeem rov ua koj qhov kev sim thiab tau txais cov txiaj ntsig zoo sib xws. Tib txoj hauv kev los ntsuas qhov kev xav yog ua qhov kev sim
Yuav ua li cas koj pom qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug?
Txhawm rau xam qhov tshwm sim ntawm qhov tshwm sim tshwm sim tsawg kawg ib zaug, nws yuav yog qhov sib ntxiv ntawm qhov xwm txheej tsis tshwm sim. Qhov no txhais tau hais tias qhov tshwm sim ntawm qhov tshwm sim yeej tsis tshwm sim thiab qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug yuav sib npaug, lossis 100% txoj hauv kev
