9 A. Evaporation ntawm dej yog a kev hloov ntawm lub cev thiab tsis yog kev hloov tshuaj vim nws yog a hloov uas ua tsis hloov cov khoom zoo li a tshuaj hloov ,ib a hloov lub cev . Plaub lub cev cov khoom uas piav txog cov kua yog thaum nws khov, boils, evaporates , los yog condenses.
Yog li, evaporation tsis yog tshuaj lom neeg hloov pauv?
Piav: Nws yog lub cev hloov vim nws mus ntawm cov kua theem mus rau theem roj. Nws yog tsis yog kev hloov tshuaj vim nws tseem yog ua los ntawm ob lub hydrogen atoms thiab ib tug oxygen atom.
Tsis tas li ntawd, yog tshem tawm ntsev los ntawm dej los ntawm evaporation ib qho tshuaj los yog lub cev hloov? Qhov no yog vim, koj tuaj yeem rov qab tau cov ntsev los ntawm evaporating tus dej nyob deb. Feem ntau a hloov lub cev yog reversible siv lub cev txhais tau tias. Piv txwv li, ntsev yaj hauv dej tuaj yeem rov qab los ntawm kev tso cai dej rau evaporate.
Kuj kom paub, yog lim dej hloov lub cev lossis tshuaj lom neeg?
Yog tias koj siv micro lim los yog ultra lim , tsis muaj tshuaj hloov thaum lim uas tsuas yog ib lub cev txheej txheem. Cov dej Cov molecules nyob twj ywm li H2O uas yog me dua kom dhau los ntawm cov pores ntawm daim nyias nyias.
Puas yog evaporation thiab condensation lub cev lossis tshuaj hloov pauv?
Melting, evaporation thiab condensation yog cov piv txwv ntawm hloov lub cev , los yog hloov ntawm xeev, thiab txawv ntawm kev hloov uas ua rau cov ntaub ntawv tshiab tsim los ntawm a tshuaj tshuaj tiv thaiv.

Yuav ua li cas hydrogen bonding ntawm cov dej molecules pab piav qhia dej lub peev xwm nqus tau ntau lub zog ua ntej evaporation?
Cov hydrogen bonds hauv dej tso cai rau nws nqus thiab tso tawm lub zog cua sov qeeb dua li ntau lwm yam khoom. Qhov kub thiab txias yog ib qho kev ntsuas ntawm qhov kev txav (kinetic zog) ntawm cov molecules. Raws li cov lus tsa suab nce, lub zog yog siab dua thiab yog li kub siab dua
Vim li cas cov evaporation ntawm dej yog piv txwv ntawm kev hloov lub cev?
Cov evaporation ntawm dej yog ib qho kev hloov ntawm lub cev. Thaum dej evaporates, nws hloov ntawm cov kua hauv lub xeev mus rau lub xeev gas, tab sis nws tseem yog dej; nws tsis tau hloov mus rau lwm yam khoom. Piv txwv li, hydrogen burning nyob rau hauv cov huab cua dhau ib tug tshuaj hloov nyob rau hauv uas nws yog hloov dua siab tshiab rau hauv dej
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
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.'
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
