Yog tias theem hloov yog nruab nrab ntawm cov khoom thiab kua cov mis zoo li q = mΔH fus thiab ΔH fus yog hu ua cua sov ntawm fusion. Yog tias theem hloov yog nruab nrab ntawm cov kua thiab roj cov qauv zoo li q = mΔ vap ua thiab ΔH vap ua yog hu ua cua sov ntawm vaporization.
Tom qab ntawd, dab tsi yog cov theem hloov pauv uas tso tawm lub zog?
Kev piav qhia: Muaj ob theem kev hloov pauv uas lub zog cua sov tso tawm: Condensation : Thaum cov roj condenses rau cov kua kom muaj nuj nqis ntawm lub zog hloov los ntawm cov tshuaj mus rau tshav kub hu ua Heat of Vaporization los yog Δ Hvap. Raws li cov pa roj cua txias, cov khoom qeeb qeeb, thiab cov ntaub ntawv ua kua.
Ib tug kuj yuav nug, dab tsi theem muaj lub siab tshaj plaws enthalpy? gas
Kuj Paub, qhov twg ntawm cov kev hloov pauv hauv qab no yog qhov hloov pauv endothermic?
Fusion, vaporization, thiab sublimation yog endothermic cov txheej txheem, whereas khov, condensation, thiab deposition yog exothermic txheej txheem. Hloov ntawm xeev yog cov piv txwv ntawm theem hloov , los yog theem kev hloov pauv. Tag nrho theem hloov yog nrog kev hloov nyob rau hauv lub zog ntawm ib tug system.
Koj txhais li cas enthalpy?
Enthalpy yog ib qho khoom siv thermodynamic ntawm ib qho system. Nws yog tus lej ntawm lub zog sab hauv ntxiv rau cov khoom ntawm lub siab thiab ntim ntawm qhov system. Nws qhia txog lub peev xwm ua haujlwm tsis yog siv tshuab thiab lub peev xwm tso tawm cua sov. Enthalpy yog denoted li H; tshwj xeeb enthalpy npe h.

Cov kev hloov ntawm lub cev txawv ntawm cov tshuaj hloov pauv li cas muab ib qho piv txwv ntawm txhua tus?
Kev hloov tshuaj lom neeg tshwm sim los ntawm cov tshuaj tiv thaiv tshuaj, thaum lub cev hloov pauv yog thaum cov teeb meem hloov pauv tab sis tsis yog tshuaj lom neeg. Piv txwv ntawm kev hloov tshuaj lom neeg yog hlawv, ua noj, xeb, thiab rotting. Piv txwv ntawm kev hloov lub cev yog boiling, melting, khov, thiab shredding
Yuav ua li cas yog lub mis rau xam cov kev sib hloov los ntawm kev soj ntsuam rotation?
Txhawm rau hloov qhov pom kev sib hloov mus rau ib qho kev sib hloov, faib cov kev sib hloov pom los ntawm qhov concentration hauv g / mL thiab txoj kev ntev hauv decimeters (dm)
Yuav ua li cas koj xam cov kev hloov nyob rau hauv equilibrium?
