Nws yog ib hloov lub cev . Hauv kev daws cov sodium thiab chlorine muaj nyob hauv lawv cov ntawv ion, tab sis yog tias koj boil deb ntawm dej ntsev yog qhov seem. Nws tseem yog ntsev thiab tsis tau hloov pauv los ntawm cov txheej txheem hydration thiab lub cev qhuav dej.
Hauv qhov no, boiling dej puas hloov lub cev?
Boiling dej npau dej yog ib qho piv txwv ntawm a hloov lub cev thiab tsis yog a tshuaj hloov vim cov dej vapor tseem muaj tib lub qauv molecular li kua dej (H2O). Yog hais tias cov npuas tau tshwm sim los ntawm decomposition ntawm ib tug molecule rau hauv cov pa roj (xws li H2O → H2 thiab O2), ces boil yuav yog a tshuaj hloov.
Tsis tas li ntawd, cov dej hiav txwv npau npau puas yog kev hloov tshuaj? Tsis muaj hloov hauv dej tshuaj mis nyuj nyob rau hauv nws cov khoom, kua, los yog vapor xeev - nws tseem zoo ib yam: H2O! Yog boiling dej raug tshem tawm ntawm tshav kub, nws nres bubbling sai heev.
Tom qab ntawd, ib tug kuj yuav nug, yog dej ntsev hloov lub cev?
Dissolving ib tug khoom nyob rau hauv cov kua, xws li lub rooj ntsev hauv dej , yog a hloov lub cev vim tsuas yog lub xeev ntawm qhov teeb meem tau hloov. Kev hloov ntawm lub cev feem ntau tuaj yeem thim rov qab. Tso cai rau dej mus evaporate yuav rov qab ntsev mus rau lub xeev khov.
Puas yog kev tawg yog kev hloov lub cev?
Cov kev tawg NaCl hauv dej yog a hloov lub cev . Vim hais tias, nws yog ib tug reversible txheej txheem. Yog tias dej evaporates, koj tau txais cov ntsev rov qab.

Qhov kub ntawm ib daim hlau zaum hauv dej npau npau yog dab tsi?
Ceeb toom qhov pib kub ntawm cov hlau (52.0 ° C). Qhov no yog qhov txawv txav ntawm cov qauv hlau feem ntau yog rhuab los ntawm immersion nyob rau hauv boiling dej, ua rau ib txwm pib kub ntawm los yog ze 100.0 ° C rau cov hlau
Dab tsi yog qhov tseeb ntawm lub cev lub cev lub cev kev xav xav?
Lub cev lub cev lub ntsiab lus kev xav (PSSH) yog ib txoj hauj lwm hauv lub tswv yim ntawm kev txawj ntse tsim los ntawm Allen Newell thiab Herbert A. 'Ib lub cim lub cev muaj qhov tsim nyog thiab txaus txhais tau tias rau kev ua haujlwm ntse.'
Puas yog dej npau npau yog lub cev lossis tshuaj lom neeg?
Dej Boiling: Cov dej kub npau npau yog ib qho piv txwv ntawm kev hloov ntawm lub cev thiab tsis yog kev hloov tshuaj lom neeg vim tias cov dej vapor tseem muaj cov qauv molecular zoo li cov kua dej (H2O). Yog hais tias cov npuas tau tshwm sim los ntawm decomposition ntawm ib tug molecule rau hauv cov pa roj (xws li H2O → H2 thiab O2), ces boiling yuav ib tug tshuaj hloov
Puas yog cov dej npau npau yog tshuaj lom neeg lossis lub cev hloov?
Boiling waterBoiling water yog ib qho piv txwv ntawm kev hloov ntawm lub cev thiab tsis yog kev hloov tshuaj lom neeg vim tias cov dej vapor tseem muaj cov qauv molecular zoo li cov kua dej (H2O). Yog hais tias cov npuas tau tshwm sim los ntawm decomposition ntawm ib tug molecule rau hauv cov pa roj (xws li H2O → H2 thiab O2), ces boiling yuav ib tug tshuaj hloov
Vim li cas evaporation ntawm dej yog hloov lub cev thiab tsis hloov tshuaj?
9 A. evaporation ntawm dej yog ib qho kev hloov ntawm lub cev thiab tsis yog tshuaj hloov vim nws yog ib qho kev hloov uas tsis hloov cov tshuaj xws li tshuaj hloov pauv, tsuas yog hloov lub cev. Plaub lub cev uas piav txog cov kua yog thaum nws khov, boils, evaporates, los yog condenses
