Nonvolatile solutes txo qhov chaw khov by thaiv cov kuab tshuaj los ntawm kev sib sau. … Thiab yog li ntawd, cov kuab tshuaj uas tsis muaj hluav taws xob ua rau nws nyuaj rau khov, txo qhov chaw khov. Tib cov kuab tshuaj kuj tseem yuav ua kom lub qhov kub hnyiab.
Puas yog qhov chaw khov kho txo qis nrog kev daws teeb meem?
Cov txiaj ntsig ntawm kev ntxiv cov kuab tshuaj rau cov kuab tshuaj muaj qhov tawm tsamntawm qhov chaw khov ntawm cov tshuaj raws li nws ua rau ntawm qhov kub. Ib qho tshuaj yuav muaj qhov qis qis dua li cov kuab tshuaj ntshiab.
Yuav ua li cas cov kuab tshuaj cuam tshuam rau qhov khov thiab cov ntsiab lus kub?
Boiling point elevation yog qhov nce ntawm cov kuab tshuaj lub boiling point vim qhov sib ntxiv ntawm cov kua. Ib yam li ntawd, kev nyuaj siab ntawm qhov dej khov yog qhov txo qis ntawm cov kuab tshuaj qhov chaw khov vim qhov sib ntxiv ntawm cov kuab tshuaj. Qhov tseeb, raws li qhov kub ntawm qhov hnyav nce, nws khov taw tes txo qis
Yuav ua li cas cov kuab tshuaj cuam tshuam qhov chaw khov?
Lub xub ntiag ntawm cov kuab tshuaj txo qis qhov khov ntawm cov kuab tshuaj; cov nyhuv no hu ua freezing-point depression. Tus yuam sij rau kev nkag siab cov nyhuv no yog tias cov kuab tshuaj muaj nyob hauv cov kua tshuaj, tab sis tsis yog nyob rau hauv cov kuab tshuaj ntshiab. Piv txwv: xav txog cov dej khov ntshiab uas ntab hauv dej ntsev.
Yuav ua li cas cov kuab tshuaj cuam tshuam rau lub boiling point?
Vim tias muaj solute particles txo qhov vapor siab ntawm cov kua ua kua, qhov kub siab dua yuav tsum ncav cuag qhov kub. Qhov no tshwm sim yog hu ua boiling point elevation. Rau txhua mole ntawm cov khoom yaj hauv ib liter dej, qhov kub ntawm cov dej nce li ntawm 0.5 ° C.
