Qhov sib txawv tseem ceeb ntawm evaporation thiab vaporization yog tias evaporation ntawm cov kua tshwm sim ntawm qhov kub thiab txias uas qis dua qhov kub ntawm cov kua, whereas vaporization tshwm sim ntawm lub boiling point ntawm cov kua.
Ob qho evaporation thiab vaporization xa mus rau cov txheej txheem uas cov kua hloov mus rau hauv nws theem gaseous. Txawm hais tias evaporation tshwm sim hauv cov kua, vaporization tuaj yeem tshwm sim hauv cov khib nyiab thiab; peb hu qhov no sublimation (hloov ntawm cov khoom theem ncaj qha mus rau theem roj yam tsis tau mus txog theem ua kua).
Evaporation yog dab tsi?
Evaporation yog qhov hloov pauv ntawm cov kua mus rau hauv nws theem gaseous ntawm qhov kub uas qis dua qhov kub ntawm cov kua. Cov molecules nyob rau hauv cov kua muaj sib txawv kinetic zog. Thaum peb muab lub zog los ntawm sab nraud mus rau cov kua (xws li cua sov), lub zog kinetic ntawm cov kua molecules nce. Thaum lub zog txaus rau cov molecules nyob rau saum npoo kom kov yeej lub zog ntawm lub cev ntawm lawv, cov molecules zoo li khiav tawm ntawm qhov chaw thiab hloov mus rau hauv lub xeev roj.
Daim duab 01: Evaporation tshwm sim ntawm qhov chaw dej
Txawm li cas los xij, qee qhov ntawm cov molecules uas nkag mus rau theem roj los ntawm evaporation tuaj yeem rov ua kua los ntawm condensation. Qhov no ua rau muaj kev sib npaug ntawm tus nqi evaporation thiab tus nqi condensation. Ntxiv mus, tas li vapor siab yog tsim nyob rau hauv theem no. Yog tias peb nce qhov kub ntawm cov kua ntawm cov ntsiab lus no, nws ua rau muaj qhov nce ntawm evaporation txij li lub zog kinetic ntawm cov molecules nce. Yog li ntawd, tus nqi ntawm cov molecules nyob qhov chaw saum cov kua nce.
Vaporization yog dab tsi?
Vaporization yog hloov pauv ntawm cov theem ua kua rau hauv theem roj ntawm qhov kub ntawm cov kua. Yog li ntawd, vaporization tshwm sim ntawm kub kub ntawm cov kua.
Daim duab 02: Dej Boiling
Yuav kom ua kua dej, lub vapor siab ntawm cov kua yuav tsum sib npaug rau sab nraud siab nyob ib puag ncig cov kua. Qhov no txhais tau hais tias cov molecules nyob rau saum npoo ntawm cov kua yuav tsum muaj ib tug kinetic zog uas txaus los kov yeej lub intermolecular rog ntawm cov kua molecules; Yog li ntawd, cov molecules no tuaj yeem tawm hauv cov kua los ntawm kev hloov mus rau theem roj.
Qhov txawv ntawm evaporation thiab vaporization yog dab tsi?
Evaporation thiab vaporization yog cov txheej txheem uas cov kua tshuaj hloov mus rau hauv nws theem gaseous. Qhov sib txawv tseem ceeb ntawm evaporation thiab vaporization yog tias evaporation ntawm cov kua tshwm sim ntawm qhov kub thiab txias uas qis dua qhov kub ntawm cov kua, qhov vaporization tshwm sim ntawm qhov kub ntawm cov kua. Ntxiv mus, evaporation tshwm sim thaum lub vapor siab ntawm cov kua qis dua lub siab sab nraud nyob ib puag ncig cov kua thaum vaporization tshwm sim thaum lub vapor siab ntawm cov kua yog sib npaug rau sab nraud siab.
Tsis tas li ntawd, thaum lub sij hawm evaporation, cov molecules ntawm cov kua dej tawm ua ntej thaum vaporization tuaj yeem tshwm sim ntawm txhua qhov chaw ntawm cov kua (yog vim li cas peb tuaj yeem pom cov npuas dej hauv qab ntawm lub thawv thaum cua sov).
Summary – Evaporation vs Vaporization
Ob qho evaporation thiab vaporization xa mus rau cov txheej txheem uas cov khoom ua kua hloov mus rau hauv nws theem gaseous. Qhov sib txawv tseem ceeb ntawm evaporation thiab vaporization yog tias evaporation ntawm cov kua tshwm sim ntawm qhov kub thiab txias uas qis dua qhov kub ntawm cov kua, qhov vaporization tshwm sim ntawm qhov kub ntawm cov kua.
