Dej evaporates ntawm 100oC. Sublimation - Qhov no yog qhov tsis tshua muaj hloov lub cev uas tshwm sim los ntawm ib yam khoom mus los ntawm ib tug loj heev kub hloov . Cov txheej txheem no hloov cov khoom rau hauv cov pa roj. Ib qho piv txwv ntawm qhov no yog thaum dej khov qhuav (khov carbon dioxide (yog li ntawd ib qho khoom)) raug rau hauv chav tsev kub.
Ib yam li ntawd, tej zaum koj yuav nug, puas yog cov dej khov qhuav yog tshuaj lom neeg lossis hloov lub cev?
Qhov no yuav tsum yog ib tshuaj hloov , vim hais tias cov khoom tshiab-"fog"-forms." Tiag tiag, dej khov qhuav undergo ib hloov lub cev thaum nws sublimates los ntawm cov khoom mus rau lub xeev gaseous yam tsis muaj thawj melting rau hauv cov kua. Tib cov pa roj carbon dioxide tseem nyob, nws tsuas yog dhau ib theem hloov los ua ib qho tsis muaj xim tsis muaj roj.
Kuj Paub, puas yog cov dej khov qhuav evaporate? Dej khov qhuav hloov ncaj qha los ntawm cov khoom mus rau cov pa roj -sublimation- nyob rau hauv ib txwm atmospheric tej yam kev mob yam tsis mus los ntawm ib tug ntub dej theem. Yog li nws tau txais lub npe " dej khov qhuav ." Raws li txoj cai dav dav, Dej khov qhuav yuav sublimate ntawm tus nqi ntawm tsib mus rau kaum phaus txhua 24 teev nyob rau hauv ib tug raug dej khov hauv siab.
Dhau li ntawm no, evaporation puas hloov lub cev?
Cov evaporation dej yog a hloov lub cev . Thaum dej evaporates , nws kev hloov los 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 huab cua undergoes a tshuaj hloov nyob rau hauv uas nws yog hloov dua siab tshiab rau hauv dej.
Puas yog sublimation hloov pauv lub cev?
Sublimation yog a hloov lub cev . Thaum cov khoom sublimes, nws kev hloov los ntawm ib tug khoom mus rau ib tug roj yam tsis tau mus txog lub kua theem. Qhov no tsis ua rau a tshuaj hloov , txawm li cas los. Cov dej khov qhuav yog cov pa roj carbon dioxide nyob rau theem khoom.

Dab tsi cov tshuaj tiv thaiv sawv cev rau lub cev qhuav dej synthesis?
Nyob rau hauv lub cev qhuav dej synthesis cov tshuaj tiv thaiv (Daim duab), cov hydrogen ntawm ib tug monomer ua ke nrog cov hydroxyl pawg ntawm lwm monomer, tso ib tug molecule ntawm dej. Nyob rau tib lub sijhawm, cov monomers sib koom electrons thiab tsim covalent bonds. Raws li cov monomers ntxiv koom nrog, cov saw hlau ntawm kev rov ua dua monomers tsim ib lub polymer
Dab tsi yog cov khoom organic tsim los ntawm lub cev qhuav dej ntawm 3 Methyl 2 Pentanol?
Acid-catalyzed lub cev qhuav dej ntawm 3-methyl-2-pentanol muab peb alkenes: 3-methyl-1-pentene, 3-methyl-2-pentene, thiab 3-methylenepentane. Kos cov qauv ntawm carbocation intermediate ua rau tsim ntawm 3-methyl-2-pentene
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
Lub cev siv lub cev qhuav dej li cas?
Ib txoj hauv kev uas nws ua qhov no yog los ntawm ob qho kev cuam tshuam tseem ceeb hu ua lub cev qhuav dej thiab hydrolysis. Cov tshuaj tiv thaiv lub cev qhuav dej txuas cov monomers ua ke rau hauv cov polymers los ntawm kev tso dej, thiab hydrolysis lov polymers rau hauv monomers siv cov dej molecule. Koj lub cev zom zaub mov los ntawm kev rhuav tshem cov molecules loj uas koj noj
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.'
