Cov txheej txheem ntawm distillation pib nrog cua sov cov kua rau boiling point. Cov kua evaporates, tsim ib vapor. Cov vapor yog tom qab ntawd txias, feem ntau dhau los ntawm cov kav dej lossis cov raj ntawm qhov kub qis dua. Cov vapor txias ces condenses, tsim ib distillate.
Hais txog qhov no, 3 kauj ruam ntawm distillation yog dab tsi?
Zuag qhia tag nrho txheej txheem ntawm cawv distillation tuaj yeem suav nrog 3 qhov chaw: fermentation, Distillation , thiab Ua tiav.
Tom qab ntawd, lo lus nug yog, fractional distillation ua haujlwm li cas ib kauj ruam? Cov kauj ruam ntawm fractional distillation yog raws li nram no:
- Koj ua kom sov qhov sib xyaw ntawm ob lossis ntau dua cov khoom (kua) nrog cov ntsiab lus sib txawv rau qhov kub siab.
- Cov sib tov boils, tsim vapor (gases); feem ntau cov khoom nkag mus rau hauv lub vapor theem.
Lub hom phiaj ntawm cov txheej txheem distillation yog dab tsi?
Feem ntau lub hom phiaj rau qhov yooj yim distillation yog los ntxuav cov dej haus ntawm cov tshuaj tsis xav tau thiab cov zaub mov xws li ntsev. Muaj ntau yam tshuab uas distil dej rau cov lub hom phiaj ntawm purification los yog hloov.
Dab tsi yog ob txoj kev koom nrog hauv distillation?
Distillation refining muaj ob txheej txheem ntawm distilling thiab condensation reflux. Distillation feem ntau yog nqa tawm hauv distillation kem, gas-kua ob -phase ntws los ntawm kev sib cuag countercurrent, theem kub thiab huab hwm coj hloov.

Dab tsi yog txheej txheem spontaneous thiab non-spontaneous txheej txheem?
Cov txheej txheem spontaneous yog ib qho uas tshwm sim yam tsis muaj kev cuam tshuam ntawm sab nraud. Ib txoj kev uas tsis yog tshwm sim yuav tsis tshwm sim yog tias tsis muaj kev cuam tshuam ntawm sab nraud
Cov txheej txheem dab tsi yog lub luag haujlwm rau txoj haujlwm ua haujlwm sib txawv?
Position-effect variegation (PEV) tshwm sim thaum cov noob ib txwm nyob hauv euchromatin yog sib xyaw nrog heterochromatin los ntawm kev hloov kho lossis hloov pauv. Thaum lub ntim ntim heterochromatin kis thoob plaws heterochromatin / euchromatin ciam teb, nws ua rau kev hloov pauv ntawm kev ntsiag to hauv tus qauv stochastic
Cov txheej txheem twg yog txheej txheem endothermic?
Cov txheej txheem endothermic yog ib qho txheej txheem uas xav tau lossis nqus lub zog los ntawm nws qhov chaw nyob ib puag ncig, feem ntau yog ua kom sov. Nws yuav yog cov txheej txheem tshuaj, xws li dissolving ammonium nitrate hauv dej, lossis cov txheej txheem ntawm lub cev, xws li melting ntawm cov dej khov nab kuab
