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..
Pom zoo:
Puas yog nws tsis pom zoo lossis tsis pom zoo?
verb (siv nrog cov khoom), dis·app·proved, dis·ap·prov·ing. xav (ib yam dab tsi) tsis ncaj ncees lawm los yog reprehensible; censure los yog condemn nyob rau hauv lub tswv yim. kom tsis txhob pom zoo los ntawm; Tsis kam rau txim: Senate tsis pom zoo rau kev xaiv tsa.
Puas yog cua sov ntawm vaporization nce nrog cov rog sib xyaws?
Lub muaj zog dua lub zog sib xyaws , qhov siab dua qhov kub ntawm fusion ntawm fusion Lub latent cua sov ntawm fusion yog qhov hloov pauv ntawm cov khoom muaj pes tsawg thaum nws melts. Thaum tshav kub ntawm fusion yog hais txog ib chav tsev ntawm qhov loj, nws feem ntau hu ua qhov tshwj xeeb kub ntawm fusion, thaum molar tshav kub ntawm fusion yog hais txog qhov hloov pauv enthalpy ib tus nqi ntawm cov khoom hauv moles.
Puas muaj cua sov ntawm vaporization?
Qhov cua sov ntawm vaporization txhais tau tias yog qhov kub ntawm qhov xav tau tig 1 g ntawm cov kua rau hauv vapor, tsis muaj qhov kub ntawm cov kua. piv txwv ntawm cua sov ntawm vaporization yog dab tsi? Kub ntawm vaporization ntawm dej Yog, dej muaj cua sov ntawm vaporization, lub zog xav tau los hloov ib gram ntawm cov khoom ua kua rau roj ntawm qhov kub thiab txias.
Puas yog pov thawj uas tsis pom zoo lossis tsis pom zoo nrog kev sib cav?
Cov lus foob: Ib qho kev thov uas tsis pom zoo lossis tsis pom zoo nrog qhov thesis / thov. (Qhov no yuav yog tus neeg tawm tsam qhov kev xav.) Rebuttal: Cov pov thawj uas tsis pom zoo lossis tsis pom zoo rau qhov kev foob foob. (Nov yog qhov uas tus menyuam kawm ntawv teb rau tus yeeb ncuab thiab qhia tias vim li cas lawv qhov kev sib cav tsis muaj zog.
Puas yog qhov tsis zoo ntawm qhov tsis txaus ntseeg tuaj yeem ntsuas tau hauv cov menyuam kawm ntawv preschool?
Cov pov thawj dav dav qhia pom tias qhov siab Callous-Unemotional (CU) zoo nyob rau hauv thaum yau thiab cov hluas tuaj yeem txhim khu kev txheeb xyuas cov tib neeg muaj kev pheej hmoo rau kev tawm tsam kev sib raug zoo. Txoj kev tshawb fawb tam sim no hais txog kev tshawb nrhiav qhov tsis sib xws los ntawm kev tshawb xyuas cov qauv ntawm CU tus cwj pwm hauv cov menyuam yaus hnub nyoog preschool.
