Yog li, xim thiab kub hloov pauv lub cev Kev hloov pauv, thaum oxidation thiab hydrolysis yog tshuaj kev hloov. tsw yog generated thaum cov tshuaj hloov muaj pes tsawg leeg. Vim li no, tsw yog a tshuaj hloov.
Tsis tas li lo lus nug yog, yog tsw lub cev lossis tshuaj lom neeg ntawm cov teeb meem?
Lub cev muaj zog : Lub cev muaj zog tuaj yeem pom lossis ntsuas yam tsis tau hloov pauv qhov muaj pes tsawg leeg ntawm teeb meem . Lub cev muaj zog muaj xws li: tsos, kev ntxhib los mos, xim, tsw , melting point, boiling point, ntom, solubility, polarity, thiab lwm yam.
Tsis tas li ntawd, yam khoom twg yog tsw tsw? Qhov no tej zaum yuav yooj yim raws li qhov teeb meem ntawm kev yooj yim. Nws yog tam sim no paub zoo tias txawv molecules muaj ib tug ntawm ob peb tsw tsw . Qhov kev xav ntawm tsw yog tsim thaum lub tsw -ua rau molecule khi rau qee qhov chaw (hu ua receptors) siab hauv qhov ntswg.
Khaws qhov no hauv kev txiav txim siab, puas yog xov tooj cua yog tshuaj lom neeg lossis lub cev?
Xov tooj cua yog txhais tias yog emission ntawm hluav taws xob los ntawm ib tug tsis ruaj tsis khov nucleus. Cov khoom no tuaj yeem yog alpha, beta thiab gamma hais. Thiab li no los ntawm kev txhais ntawm tshuaj thiab lub cev muaj zog , radioactivity yog a chemical khoom.
Puas yog porosity yog lub cev lossis tshuaj lom neeg?
Lub cev muaj zog suav nrog daim ntawv (particulate lossis bulk); porosity (micro- lossis macroporosity, tsis yog- lossis kev sib txuas porosity ); thaj chaw saum npoo; thiab crystallinity (reflecting crystal size, crystal perfection, thiab grain loj raws li cuam tshuam los ntawm sintering tej yam kev mob). Chemical Properties.

Puas yog kev sib xyaw ntsev thiab kua txob yog lub cev lossis tshuaj lom neeg?
Piv txwv li, sib tov ntsev thiab kua txob tsim ib yam khoom tshiab yam tsis tau hloov cov tshuaj pleev ib ce ntawm ob qho tib si. Lawv kuj yog lub cev hloov pauv vim lawv tsis hloov qhov xwm txheej ntawm cov khoom
Puas yog Lithium yog lub cev lossis tshuaj lom neeg?
Lithium Properties Lithium muaj qhov melting point ntawm 180.54 C, kub taw tes ntawm 1342 C, qhov tshwj xeeb lub ntiajteb txawj nqus ntawm 0.534 (20 C), thiab valence ntawm 1. Nws yog lub lightest ntawm cov hlau, nrog ib tug ceev kwv yees li ib nrab ntawm cov dej. . Nyob rau hauv cov xwm txheej zoo tib yam, lithium yog qhov tsawg kawg nkaus ntawm cov khoom siv
Puas yog hluav taws kub nyhiab yog qhov hloov pauv ntawm lub cev lossis tshuaj lom neeg?
Thaum cov roj hlawv nws feem ntau ua ke nrog oxygen kom muab cov pa roj carbon dioxide, dej thiab lwm yam nrog rau kev tso tawm ntawm lub zog. Los ntawm kev txhais, nws yog kev hloov tshuaj
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
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
