Piv txwv ntawm Distillation
Cov dej ntsev yog hloov mus rau hauv dej tshiab los ntawm distillation . Ntau hom roj, xws li roj av, yog cais los ntawm cov roj crude los ntawm distillation . Alcoholicbeverages yog tsim los ntawm distillation . Cov cawv yog boiled tawm ntawm qhov seem ntawm qhov sib tov thiab sau rau hauv aconcentrated hom.
Ntawm no, piv txwv li cas yog qhov yooj yim distillation?
Ib tug thib peb piv txwv ntawm yooj yim distillation , thiab tej zaum qhov paub zoo tshaj plaws, yog kev sib cais ntawm ethanol los ntawm dej. Cawv muaj qhov kub kub qis dua li dej, yog li thaum sib xyaw xws li cawv tau rhuab, cawv pib evaporate ua ntej dej. Nws txias thiab tom qab ntawd condenses rov qab rau hauv cov kua dej.
Tsis tas li ntawd, dab tsi yog siv rau distillation? Distillation yog siv cais cov kua dej los ntawm cov khoom tsis muaj hluav taws xob, xws li hauv kev sib cais ntawm cov cawv cawv los ntawm cov khoom siv fermented, los yog hauv kev sib cais ntawm ob lossis ntau cov kua dej muaj cov ntsiab lus sib txawv, xws li hauv kev sib cais ntawm cov roj av, roj av, thiab cov roj lubricating los ntawm crudeoil.
Xav txog qhov no, dab tsi yog distillation thiab piv txwv?
Cov ntsiab lus tseem ceeb: Distillation ntawm Distillation yog cov txheej txheem ntawm kev sib cais ntawm cov khoom sib tov raws li cov ntsiab lus sib txawv. Piv txwv ntawm kev siv ntawm distillation muaj xws li purification ntawm cawv, desalination, crude roj refining, thiab ua liquefiedgases los ntawm huab cua.
Dab tsi yog hom distillation?
Qee yam tseem ceeb ntawm distillation muaj xws li:
- Yooj yim distillation.
- Fractional distillation.
- Chav distillation.
- Nqus distillation.
- Cua-sensitive nqus distillation.
- Txoj kev luv distillation.
- Zone distillation.
Pom zoo:
Dab tsi yog qhov zoo ntawm fractional distillation tshaj qhov yooj yim distillation?
Fractional distillation yog qhov ua tau zoo dua hauv kev sib cais cov kev daws teeb meem zoo tshaj plaws rau hauv lawv cov khoom ntshiab dua li qhov yooj yim distillation. rau cov kev daws teeb meem uas sib txawv me ntsis ntawm Raoult txoj cai, txoj kev tseem tuaj yeem siv rau kev sib cais tag nrho
Thaum lub ntim ntawm ib qho piv txwv ntawm cov pa roj yog txo lub siab ntawm cov qauv ntawm cov pa roj?
Kev txo qis Cov pa roj sib xyaw txoj cai hais tias lub siab ntawm cov pa roj yog inversely cuam tshuam nrog lub ntim thiab ncaj qha ntsig txog qhov kub thiab txias. Yog tias qhov kub thiab txias yog nyob tas li, qhov sib npaug raug txo rau Boyle txoj cai. Yog li ntawd, yog tias koj txo qhov siab ntawm cov roj av tas li, nws qhov ntim yuav nce ntxiv
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
