Cov nyhuv ntawm Raoult's Law yog tias qhov saturated vapor siab ntawm kev daws yuav qis dua li ntawm cov kuab tshuaj ntshiab ntawm txhua qhov kub thiab txias. Qhov ntawd muaj tseem ceeb cuam tshuam rau ntawm daim duab theem ntawm cov kuab tshuaj.
Tsis tas li ntawd, Raoult Txoj Cai siv rau dab tsi?
ːuːlz/ txoj cai ) yog a txoj cai ntawm thermodynamics tsim los ntawm Fabkis chemist François-Marie Raoult nyob rau hauv 1887. Nws hais tias ib nrab siab ntawm txhua feem ntawm ib tug zoo tagnrho sib tov ntawm cov kua yog sib npaug zos rau lub vapor siab ntawm cov ntshiab tivthaiv multiplied los ntawm nws mole feem nyob rau hauv cov sib tov.
Ib yam li ntawd, dab tsi ua rau muaj kev sib txawv ntawm Raoult Txoj Cai? Yog hais tias cov kuab tshuaj thiab cov kuab tshuaj tsis yog nruj nreem khi rau ib leeg raws li lawv muaj rau lawv tus kheej, ces cov tshuaj yuav qhia ib tug Qhov zoo sib txawv ntawm Raoult txoj cai vim hais tias cov kuab tshuaj molecules yuav pom nws yooj yim dua kom dim ntawm kev daws mus rau theem roj.
Ib yam li ntawd, nws tau nug, Dab tsi yog qhov tseem ceeb ntawm Raoult Txoj Cai?
Qhov txo qis ntawm vapor siab ntawm cov kuab tshuaj yog proportional rau qhov concentration ntawm cov kuab tshuaj yog hu ua Raoult txoj cai.
Raoult's Law formula yog dab tsi?
Raoult txoj cai yog tshuaj txoj cai uas hais tias lub vapor siab ntawm ib qho kev daws yog nyob ntawm qhov mole feem ntawm cov kua nplaum ntxiv rau cov tshuaj. Raoult's Law yog qhia los ntawm qauv : Pdaws = Χkuab tshuajP0kuab tshuaj. qhov twg. Pdaws yog lub vapor siab ntawm cov tshuaj.

Txoj cai ntawm kev txuag ntawm huab hwm coj tseem ceeb heev rau kev kawm thiab tsim cov tshuaj tiv thaiv. Yog tias cov kws tshawb fawb paub txog qhov ntau thiab cov cim ntawm cov tshuaj reactants rau ib qho tshuaj tiv thaiv, lawv tuaj yeem kwv yees tus nqi ntawm cov khoom uas yuav ua
Vim li cas Kepler txoj cai thib peb tseem ceeb?
Kepler txoj cai thib peb ntawm kev txav mus los ntawm lub ntiaj teb hais tias qhov nruab nrab ntawm lub ntiaj teb los ntawm lub hnub cubed yog ncaj qha proportional rau lub sij hawm orbital squared. Newton pom tias nws txoj cai lub ntiajteb txawj nqus tuaj yeem piav qhia Kepler txoj cai. Kepler pom txoj cai no ua haujlwm rau cov ntiaj chaw vim tias lawv txhua tus orbit tib lub hnub qub (Lub Hnub)
Vim li cas qhov tseem ceeb ntawm qhov tseem ceeb?
Thaum koj pom tus nqi kiag li hauv qhov teeb meem lossis qhov sib npaug, nws txhais tau hais tias txhua yam nyob hauv tus nqi tiag tiag yog qhov zoo. Cov txiaj ntsig tsis zoo feem ntau siv rau hauv cov teeb meem cuam tshuam nrog kev nyob deb thiab qee zaum siv nrog qhov tsis sib xws. Qhov ntawd yog qhov tseem ceeb uas yuav tsum nco ntsoov nws zoo li qhov deb ntawm xoom
Txoj cai ntawm kev txuag huab hwm coj yog dab tsi thiab vim li cas nws tseem ceeb?
Txoj cai ntawm kev txuag ntawm huab hwm coj tseem ceeb heev rau kev kawm thiab tsim cov tshuaj tiv thaiv. Yog tias cov kws tshawb fawb paub txog qhov ntau thiab cov cim ntawm cov tshuaj reactants rau ib qho tshuaj tiv thaiv, lawv tuaj yeem kwv yees tus nqi ntawm cov khoom uas yuav ua
Vim li cas cov nuj nqis tseem ceeb tseem ceeb thaum qhia txog kev ntsuas?
Cov duab tseem ceeb yog qhov tseem ceeb los qhia qhov tseeb ntawm koj cov lus teb. Qhov no yog qhov tseem ceeb hauv kev tshawb fawb thiab engineering vim tias tsis muaj cov cuab yeej ntsuas tuaj yeem ua qhov ntsuas nrog 100% precision. Siv cov nuj nqis tseem ceeb tso cai rau tus kws tshawb fawb paub tias cov lus teb meej npaum li cas, lossis qhov tsis paub meej npaum li cas
