A reflux apparatus tso cai rau kom yooj yim cua sov ntawm ib qho kev daws teeb meem, tab sis tsis poob ntawm cov kuab tshuaj uas yuav tshwm sim los ntawm cua sov nyob rau hauv ib tug qhib lub nkoj. Hauv ib reflux kev teeb tsa, cov kuab tshuaj vapors raug kaw los ntawm lub condenser, thiab cov concentration ntawm reactants tseem nyob tas li thoob plaws hauv cov txheej txheem.
Dhau li ntawm qhov no, dab tsi yog qhov taw tes ntawm reflux hauv organic chemistry?
Reflux Nws yog ib qho txheej txheem uas cuam tshuam nrog cov condensation ntawm vapors thiab rov qab los ntawm cov condensate no mus rau qhov system los ntawm nws keeb kwm. Nws yog siv nyob rau hauv industrial thiab laboratory distillations. Nws kuj yog siv rau hauv chemistry muab lub zog rau cov tshuaj tiv thaiv nyob rau lub sijhawm ntev.
Lub reflux condenser ua haujlwm li cas? Txhawm rau tiv thaiv cov kuab tshuaj los ntawm kev npau taws, a reflux condenser yog siv. Qhov no yog iav kem nrog ib kab thib ob nyob ib puag ncig nws los ntawm cov dej txias ntws. Raws li vapor los ntawm cov kuab tshuaj boiling nce mus rau hauv kem ntawm lub reflux condenser , nws yog txias los ntawm lub tsho ntawm cov dej nyob rau sab nraud thiab condenses.
Ua raws li qhov no, vim li cas peb thiaj li yuav tsum tau reflux?
A reflux yog ua nyob rau hauv ib tug tshuaj tiv thaiv kom ib tug tov yuav rhuab mus rau ib tug boiling point yam tsis tau poob cov kuab tshuaj rau evaporation. Yog koj Ua kom sov cov kua dej rau nws qhov kub, qhov tsis tuaj yeem, thiab qhov tshwm sim, qhov tshwm sim yog evaporation, thiab yog li poob ntawm koj cov kuab tshuaj.
Dab tsi yog qhov txawv ntawm reflux thiab distillation?
Lub ntsiab Qhov sib txawv ntawm reflux thiab distillation yog tias reflux txoj kev siv los ua kom tiav cov tshuaj tiv thaiv qee yam thaum distillation yog siv los cais cov khoom hauv a sib tov.

Dab tsi yog qhov txawv ntawm daim ntawv qhia lub hom phiaj thiab daim ntawv qhia lub hom phiaj tshwj xeeb?
Qhov tseem ceeb hauv daim ntawv qhia dav dav yog nyob ntawm qhov chaw. Phab ntsa daim duab qhia chaw, feem ntau daim ntawv qhia pom nyob rau hauv atlases, thiab txoj kev maps yog tag nrho cov nyob rau hauv qeb no. Thematic maps, tseem hu ua daim ntawv qhia tshwj xeeb, qhia txog thaj chaw faib khoom ntawm ib lub ntsiab lus lossis qhov tshwm sim
Lub hom phiaj ntawm alternation ntawm tiam nyob rau hauv cov nroj tsuag yog dab tsi?
Kev hloov ntawm ntau tiam neeg tso cai rau ob qho tib si dynamic thiab volatile act of sexual reproduction thiab tus khov kho thiab ib txwm ua ntawm asexual reproduction. Thaum cov sporophyte tsim cov spores, cov hlwb raug mob meiosis, uas tso cai rau lub cim gametophyte rov ua dua cov noob caj noob ces tam sim no
Lub hom phiaj ntawm coolant coolant twj nyob rau hauv lub nuclear reactor yog dab tsi?
Lub hom phiaj ntawm lub reactor coolant twj tso kua mis yog muab yuam thawj coolant ntws mus tshem tawm thiab hloov cov nqi ntawm tshav kub generated nyob rau hauv lub reactor core
Lub hom phiaj ntawm ATP yog dab tsi hauv kev ua pa ntawm tes thiab photosynthesis?
Hauv qhov tseeb, nws yog qhov rov qab cov tshuaj tiv thaiv ntawm photosynthesis. Thaum nyob rau hauv photosynthesis carbon dioxide reacts nrog dej raws li catalyzed los ntawm tshav ntuj los ua suab thaj thiab oxygen, cellular respiration siv cov pa oxygen thiab zom cov suab thaj los ua carbon dioxide thiab dej nrog los ntawm kev tso tawm ntawm tshav kub, thiab zus tau tej cov ATP
Hom phiaj phiaj xwm phiaj xwm yog Mercator daim ntawv qhia?
Mercator projection. Mercator projection, hom phiaj xwm phiaj xwm qhia hauv 1569 los ntawm Gerardus Mercator. Nws yog feem ntau piav raws li ib tug cylindrical projection, tab sis nws yuav tsum tau muab los ntawm lej
