Qhov sib txawv tseem ceeb ntawm kev sib xyaw ua ke thiab nag lossis daus yog qhov sib xyaw ua ke yog qhov hloov pauv ntawm lub cev lub cev ntawm cov teeb meem los ntawm theem gaseous mus rau theem ua kua thaum nag lossis daus yog qhov hloov pauv ntawm lub cev ntawm cov teeb meem los ntawm theem aqueous mus rau theem khoom.
Condensation thiab nag lossis daus yog ob qhov xwm txheej tseem ceeb uas peb ntsib hauv peb lub neej niaj hnub. Cov xwm txheej xws li kev tsim dej khov thiab tsim cov tee dej nyob ib puag ncig cov dej txias tuaj yeem piav qhia siv cov xwm txheej no. Los nag thiab condensation muaj ntau yam kev siv nyob rau hauv kev tshuaj ntsuam chemistry, industrial chemistry, txheej txheem engineering, thermodynamics thiab txawm kev kho mob sciences. Nws yog ib qho tseem ceeb kom muaj kev nkag siab zoo ntawm cov xwm txheej no kom nkag siab meej txog lawv cov ntawv thov.
Dab tsi yog Condensation?
Condensation yog qhov hloov pauv ntawm lub cev ntawm cov teeb meem los ntawm theem gaseous mus rau theem ua kua. Vaporization yog cov txheej txheem thim rov qab ntawm kev sib xyaw ua ke. Condensation tuaj yeem tshwm sim vim muaj ntau yam.
Kev nkag siab zoo ntawm cov vapor saturated yog qhov tseem ceeb txhawm rau kom muaj kev nkag siab meej txog kev sib xyaw. Vaporization txheej txheem pib thaum peb sov cov kua rau hauv nws lub boiling point. Vaporization txuas ntxiv mus txog thaum tag nrho cov ntim ntawm cov kua evaporates. Thaum kawg, cov kua hloov mus rau hauv cov pa roj. Txawm li cas los xij, yog tias qhov ntsuas kub ntawm lub kaw lus poob qis dua qhov kub kub, cov vapor pib ua kua. Yog li ntawd, condensation yog txheej txheem ntawm kev hloov vapor rau hauv cov kua.

Condensation kuj tuaj yeem ua tiav los ntawm kev ua kom qhov kub thiab txias thiab ua kom lub zog siab. Qhov no yuav ua rau qhov tseeb qhov kub hnyiab tau nce, thiab lub vapor yuav tsum condensed. Tam sim ntawd poob rau hauv qhov kub thiab txias tuaj yeem ua rau condensation. Qhov no yog qhov tshwm sim uas piav qhia txog kev tsim cov lwg nyob ib puag ncig ib qho dej txias.
nag xob nag cua yog dab tsi?
Precipitation yog qhov hloov pauv ntawm lub cev lub cev ntawm cov teeb meem los ntawm theem aqueous mus rau theem khoom. Yog li, qhov no yog cov txheej txheem rov qab ntawm kev sib cais. Cov dej nag yog ze ze nrog solubility. Ntxiv mus, solubility ntawm ib yam khoom yog nyob ntawm qhov kub thiab txias. Ib qho kev daws teeb meem ntawm qhov kub siab dua tuaj yeem tuav cov teeb meem ntau dua li qhov kub qis dua. Thaum peb yaj cov khoom hauv cov kua, nws mus txog qhov chaw uas nws tsis yaj lawm. Peb hu qhov no lub ntsiab lus saturation. Saturation yog qhov pib ntawm nag lossis daus. Yog tias peb txo qhov kub ntawm cov tshuaj saturated, nag lossis daus pib thiab muab cov khoom hu ua precipitate. Hauv kev ua kom huv ntawm cov khoom sib txawv, nag lossis daus yog cov txheej txheem uas tau siv dav. Cov khoom tuaj yeem ua kom huv si siv txoj kev hu ua recrystallization.

Dhau li ntawm qhov tshwm sim saum toj no, nag lossis daus kuj hais txog cov txheej txheem ntawm cov tee dej ua kom loj dua thiab loj dua kom lawv poob rau hauv lub ntiajteb txawj nqus los ntawm huab cua.
Dab tsi yog qhov zoo sib xws ntawm Condensation thiab nag lossis daus?
- Condensation thiab nag lossis daus yog ob qhov kev hloov pauv hauv lub cev ntawm qhov teeb meem.
- Ob leeg yog qhov tshwm sim tseem ceeb.
- Qhov tseeb, nag lossis daus yog theem tom ntej tom qab condensation.
Qhov txawv ntawm Condensation thiab Precipitation yog dab tsi?
Condensation yog lub xeev hloov ntawm cov teeb meem los ntawm cov pa roj mus rau cov kua thaum nag lossis daus yog lub xeev hloov ntawm cov teeb meem los ntawm theem aqueous mus rau lub xeev khov. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm condensation thiab nag lossis daus. Tsis tas li ntawd, condensation nyob ntawm qhov kub thiab txias ntawm qhov system, thaum nag lossis daus nyob ntawm qhov kub thiab txias ntawm cov tshuaj. Qhov no yog lwm qhov sib txawv ntawm condensation thiab nag lossis daus.
Summary – Condensation vs Precipitation
Condensation thiab nag lossis daus yog ob qhov tshwm sim cuam tshuam nrog kev hloov pauv ntawm lub cev ntawm cov teeb meem ntawm ib lub xeev mus rau lwm qhov. Condensation yog hais txog kev hloov ntawm lub cev lub cev ntawm cov teeb meem los ntawm theem gaseous mus rau theem ua kua thaum nag lossis daus yog hais txog kev hloov pauv ntawm lub cev ntawm cov teeb meem los ntawm theem aqueous mus rau theem khoom. Yog li ntawd, qhov no yog qhov sib txawv tseem ceeb ntawm condensation thiab nag lossis daus.
