Qhov sib txawv tseem ceeb ntawm kev ua kom khov thiab khov yog qhov sib xyaw yog qhov hloov pauv ntawm lub xeev vapor mus rau hauv lub xeev ua kua whereas khov yog hloov dua siab tshiab ntawm lub xeev ua kua rau hauv lub xeev khov.
Condensation thiab khov yog qhov sib txawv ntawm qhov kub thiab txias, feem. Boiling yog hais txog kev hloov pauv ntawm cov kua rau hauv vapor thaum condensation yog hais txog kev hloov pauv ntawm vapor rau hauv cov kua. Melting yog hais txog kev hloov pauv ntawm cov khoom rau hauv cov kua thaum khov yog hloov cov kua rau hauv cov khoom.
Dab tsi yog Condensation?
Condensation yog hloov dua siab tshiab ntawm ib yam khoom (xws li dej) los ntawm lub xeev vapor mus rau lub xeev cov kua denser, feem ntau pib los ntawm kev txo qhov kub ntawm lub vapor. Li no, nws yog qhov hloov ntawm theem ntawm cov teeb meem los ntawm cov roj mus rau cov kua theem. Nws yog qhov opposite ntawm boiling. Condensation pib nrog tsim ntawm atomic los yog molecular pawg. Yog hais tias tsis yog, condensation pib thaum lub gaseous theem ntawm ib yam khoom los rau hauv kev sib cuag nrog ib tug kua los yog ib tug khoom nto. Qhov kub ntawm qhov txheej txheem no tshwm sim yog hu ua dew point.

Condensation tuaj yeem pom nyob rau hauv qhov xwm txheej, tshwj xeeb tshaj yog nyob rau hauv lub voj voog dej. Yog li ntawd, nws yog ib qho xwm txheej tshwm sim. Hauv lub voj voog dej, cov dej vapor hauv huab cua hloov mus ua kua dej. Qhov condensation no yog lub luag haujlwm rau kev tsim huab.
Yuav ua li cas khov?
Freezing yog qhov hloov pauv ntawm cov kua hauv lub xeev mus rau hauv lub xeev khov thaum qhov kub thiab txias txo qis dua qhov khov ntawm cov kua ntawd. Nyob rau hauv lwm yam lus, nws yog lub solidification ntawm ib tug kua thaum txias. Rau feem ntau cov khoom, melting point thiab freezing point yog tib yam; Txawm li cas los xij, muaj qee qhov tshwj xeeb xws li agar.

Kev khov feem ntau tshwm sim hauv daim ntawv ntawm crystallization. Ntawm no, cov muaju tsim los ntawm cov kua sib xws. Tsis tas li ntawd, nws yog thawj qhov kev txiav txim thermodynamic theem hloov. Qhov ntawd txhais tau tias; kom txog rau thaum cov khoom thiab cov kua coexist, qhov kub ntawm qhov system tseem nyob ntawm lub melting point. Piv txwv li, yog tias peb xav txog dej, thaum tso tawm, dej hauv lub xeev ua kua hloov mus rau hauv cov dej khov hauv lub xeev.
Dab tsi yog qhov zoo sib xws ntawm Condensation thiab khov?
- Condensation thiab khov yog cov tshuaj tiv thaiv tawm tsam kub thiab yaj, feem.
- Ntxiv mus, ob qho tib si condensation thiab khov khov tshwm sim thaum txo qhov kub ntawm qhov system.
Qhov txawv ntawm Condensation thiab khov yog dab tsi?
Qhov sib txawv tseem ceeb ntawm kev ua kom khov thiab khov yog qhov sib xyaw ua ke yog hloov pauv ntawm lub xeev vapor mus rau hauv lub xeev ua kua whereas khov yog hloov pauv ntawm cov kua hauv lub xeev mus rau lub xeev. Qhov kawg tshwm sim ntawm condensation yog ib tug denser kua, tab sis nyob rau hauv khov, cov khoom kawg yog ib tug khoom compound uas tsim raws li muaju. Piv txwv li, condensation ntawm dej vapor muab cov dej hauv lub xeev ua kua, whereas cov dej khov hauv lub xeev ua kua muab dej khov. Tsis tas li ntawd, qhov kub thiab txias ntawm qhov condensation tshwm sim yog hu ua dew point whereas qhov kub ntawm qhov khov tshwm sim yog qhov khov.
Hauv qab infographic qhia txog qhov sib txawv ntawm kev sib xyaw thiab khov.
Summary – Condensation vs Freezing
Condensation thiab khov yog qhov sib txawv ntawm qhov kub thiab txias, feem. Nyob rau hauv luv luv, qhov sib txawv tseem ceeb ntawm condensation thiab khov yog tias condensation yog hloov dua siab tshiab ntawm lub xeev vapor mus rau hauv lub xeev ua kua, whereas khov yog hloov dua siab tshiab ntawm cov kua xeev mus solid-state.
