Lub enthalpy ntawm condensation (los yog cua sov ntawm condensation) yog los ntawm txhais tau tias sib npaug zos rau enthalpy ntawm vaporization nrog rau qhov opposite sign: enthalpy hloov ntawm vaporization yeej ib txwm zoo (kub yog absorbed los ntawm cov khoom), whereas enthalpy hloov pauv ntawm condensation ib txwm tsis zoo (kub tawm los ntawm cov khoom) …
Puas yog entropy ntawm vaporization zoo lossis tsis zoo?
Qhov entropy ntawm vaporization yog qhov nce hauv entropy thaum vaporization ntawm cov kua. Qhov no yog ib txwm zoo, txij li qib ntawm kev tsis sib haum xeeb nce hauv kev hloov pauv ntawm cov kua hauv qhov ntim me me mus rau qhov vapor lossis roj nyob hauv qhov chaw loj dua.
Dab tsi cuam tshuam rau enthalpy ntawm vaporization?
Yog li qhov kub ntawm Vaporization yog tib yam rau ob txoj haujlwm, tsuas yog qhov zoo (endogonic / endothermic) rau evaporation thiab tsis zoo (exergonic / exothermic) rau condensation. Lwm yam khoom uas cuam tshuam rau tus nqi ntawm DHvap yog qhov hnyav molecular lossis qhov loj ntawm cov molecule.
txhais li cas yog enthalpy tsis zoo?
Kev hloov pauv tsis zoo yog sawv cev qhov kev hloov pauv huab cua uas lub zog tawm los ntawm cov tshuaj tiv thaiv, qhov kev hloov pauv enthalpy zoo sawv cev rau cov tshuaj tiv thaiv endothermic qhov twg lub zog raug coj los ntawm ib puag ncig.
Dab tsi yog qhov latent cua sov ntawm vaporisation?
Ib yam li ntawd, cov cua sov latent ntawm vaporization lossis evaporation(Lv) yog tshav kub uas yuav tsum tau muab rau ib chav tsev loj ntawm cov khoom siv los hloov nws los ntawm cov kua mus rau theem vapor yam tsis muaj qhov kub thiab txias..
