Cov npe ntawm cov kev hloov hauv xeev yog melting, khov, boiling, condensation, sublimation thiab deposition. Qhov kub ntawm ib yam khoom yuav nce mus txog rau thaum nws mus txog qhov twg qhov kev hloov yuav tshwm sim . Nws yuav nyob ntawm qhov kub thiab txias mus txog thaum ntawd hloov ua tiav.
Hais txog qhov no, 4 lub xeev hloov pauv li cas?
Cov khoom hauv ntiaj teb tuaj yeem muaj nyob hauv ib qho ntawm plaub theem, tab sis feem ntau, lawv muaj nyob hauv ib qho ntawm peb: khoom, kua lossis roj. Kawm txog rau qhov kev hloov pauv ntawm theem: khov , yaj , condensation , vaporization , sublimation thiab tso nyiaj.
Ib tug kuj yuav nug, qhov piv txwv ntawm kev hloov lub xeev yog dab tsi? Theem kev hloov muaj xws li vaporization, condensation, melting, freezing, sublimation, thiab deposition. Evaporation, ib hom vaporization, tshwm sim thaum cov khoom ntawm cov kua mus txog lub zog txaus kom tawm ntawm cov kua thiab hloov rau hauv cov pa xeev . Ib piv txwv ntawm evaporation yog ib tug pas dej ua ke qhuav tawm.
Ntawm no, qhov teeb meem hloov ntawm ib lub xeev mus rau lwm qhov li cas?
Teeb meem tuaj yeem hloov ntawm ib lub xeev mus rau lwm qhov yog cua sov los yog txias. Yog hais tias dej khov (ib qho khoom) yog rhuab nws kev hloov mus rau dej (kua kua). Qhov no hloov hu ua MELTING. Yog tias dej rhaub, nws kev hloov rau ncu (gas).
Lub ntsiab txhais ntawm kev hloov ntawm lub xeev yog dab tsi?
1. lub xeev hloov -a hloov los ntawm ib xeev (khoom los yog kua los yog roj) rau lwm yam tsis muaj a hloov nyob rau hauv tshuaj muaj pes tsawg leeg. theem hloov , theem kev hloov, lub cev hloov . khov, khov - tshem tawm ntawm tshav kub mus rau hloov ib yam dab tsi los ntawm cov kua mus rau ib qho khoom. liquefaction - kev hloov pauv ntawm cov khoom lossis cov roj rau hauv cov kua.

Qhov twg tshwm sim thawj lub teeb nyob ntawm qhov tshwm sim lossis lub teeb ywj pheej?
Lub Teeb-Dependent thiab Lub Teeb-Independent Reactions. Cov tshuaj tiv thaiv lub teeb, lossis cov tshuaj tiv thaiv lub teeb-dependent, yog thawj zaug. Peb hu lawv ob leeg thiab ob lub npe. Nyob rau hauv lub teeb-dependent tshwm sim ntawm photosynthesis, lub zog ntawm lub teeb propels lub electrons los ntawm ib tug photosystem mus rau lub high-zog lub xeev
Tus qauv yuav pab nrhiav qhov tshwm sim ntawm qhov kev tshwm sim sib xyaw li cas?
Lub ntsiab lus ntawm Qhov Muaj Peev Xwm Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej yog ib qho uas muaj ntau tshaj li qhov ua tau. Kev txiav txim siab qhov yuav tshwm sim ntawm qhov kev tshwm sim sib xyaw suav nrog kev nrhiav cov lej ntawm qhov tshwm sim ntawm tus kheej cov xwm txheej thiab, yog tias tsim nyog, tshem tawm qhov muaj feem sib tshooj
Yuav ua li cas yog qhov tshwm sim ntawm seafloor nthuav dav ntawm qhov loj ntawm lub hiav txwv pem teb?
Mid-ocean ridges thiab seafloor nthuav dav tuaj yeem cuam tshuam cov dej hiav txwv. Raws li dej hiav txwv crust txav deb ntawm qhov ntiav nruab nrab ntawm dej hiav txwv ridges, nws txias thiab dab dej thaum nws ua ntom. Qhov no ua rau kom qhov ntim ntawm dej hiav txwv phiab thiab txo cov dej hiav txwv
Yuav ua li cas koj pom qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug?
Txhawm rau xam qhov tshwm sim ntawm qhov tshwm sim tshwm sim tsawg kawg ib zaug, nws yuav yog qhov sib ntxiv ntawm qhov xwm txheej tsis tshwm sim. Qhov no txhais tau hais tias qhov tshwm sim ntawm qhov tshwm sim yeej tsis tshwm sim thiab qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug yuav sib npaug, lossis 100% txoj hauv kev
Thaum twg cov khoom hloov pauv ncaj qha mus rau cov roj, qhov kev hloov ntawm lub xeev hu ua?
Sublimation yog tus txheej txheem ntawm transformation ncaj qha los ntawm cov khoom theem mus rau lub gaseous theem, tsis dhau los ntawm ib tug nruab nrab kua theem. Tsis tas li ntawd, nyob rau hauv qhov siab ntawm qhov siab ntawm triple point, qhov kub thiab txias yuav ua rau cov khoom hloov pauv mus rau cov roj yam tsis tau dhau los ntawm cov dej hauv cheeb tsam
