Hauv ib nuclear chaw nres tsheb fais fab nuclear roj tau txais a tswj cov tshuaj tiv thaiv kab mob hauv reactor ua kom sov - nuclear kom sov zog. Cov chain reaction yog tswj los ntawm Boron tswj rods. Thaum Boron absorbs cov neutrons ces cov chain reaction yuav qeeb vim tsis muaj neutrons tsim cov tshuaj tiv thaiv.
Tsis tas li ntawd, yuav ua li cas tswj cov saw hlau nuclear tswj hauv cov chaw tsim hluav taws xob nuclear?
Hauv kev ua haujlwm ntawm a nuclear reactor , cov roj sib dhos tau muab tso rau hauv qhov chaw thiab tom qab ntawd cov pas nrig tswj tau maj mam nqa mus txog thaum a chain reaction tuaj yeem txhawb nqa. Raws li cov tshuaj tiv thaiv nce, tus naj npawb ntawm uranium-235 nuclei txo qis thiab fission by-products uas nqus neutrons tsim.
Tom qab ntawd, lo lus nug yog, dab tsi yog cov saw hlau cov tshuaj tiv thaiv hauv lub tshuab hluav taws xob nuclear? Nuclear Chain Reactions . A chain reaction hais txog cov txheej txheem uas cov neutrons tso rau hauv fission tsim ib qho ntxiv fission tsawg kawg yog ib qho ntxiv nucleus. Qhov no nucleus nyob rau hauv lem tsim neutrons, thiab cov txheej txheem rov ua dua. Cov txheej txheem tuaj yeem tswj tau ( nuclear lub zog) lossis tsis muaj zog ( nuclear riam phom).
Ua raws li qhov kev pom no, yuav ua li cas ceev ntawm cov tshuaj tiv thaiv kab mob nuclear tswj tau li cas?
Hauv ib nuclear fais fab nroj tsuag, lub tswj rods tau tsa thiab txo qis rau hauv cov roj uranium. Thaum qis qis, tag nrho cov pas nrig yog ib puag ncig los ntawm cov roj thiab nqus feem ntau ntawm cov neutrons. Nyob rau hauv tas li ntawd, lub chain reaction nres. Raws li cov pas nrig tau tsa, tsawg dua ntawm txhua tus pas nrig absorbs neutrons, thiab cov chain reaction ceev nce.
Vim li cas cov saw hlau tsis tshwm sim hauv lub tshuab hluav taws xob nuclear?
A nuclear tawg ua tsis tau tshwm sim vim roj tsis yog compact txaus tso cai rau ib qho kev tswj tsis tau chain reaction . Lub MIT reactor muaj ntau cov dej thiab cov ntaub ntawv tseem ceeb uas ua rau cov neutrons qeeb ua ntej lawv mus txog lwm cov fissile atoms.

Vim li cas cov tshuaj tiv thaiv kev zom zaub mov hu ua hydrolysis cov tshuaj tiv thaiv?
Thaum lub sij hawm zom mov, piv txwv li, decompositionreactions zom cov zaub mov loj rau hauv cov me me los ntawm kev ntxiv cov dej molecules. Hom tshuaj no hu ua hydrolysis. Raws li dej absorbs heatenergy, qee lub zog yog siv los rhuav tshem hydrogenbonds
Yuav ua li cas rau lub zog nyob rau hauv ib tug endothermic cov tshuaj tiv thaiv?
Cov tshuaj tiv thaiv kab mob endothermic tshwm sim thaum lub zog siv los rhuav tshem cov ntawv cog lus hauv cov reactants ntau dua li lub zog muab tawm thaum cov ntawv cog lus tsim hauv cov khoom. Qhov no txhais tau hais tias tag nrho cov tshuaj tiv thaiv yuav siv lub zog, yog li ntawd muaj qhov kub thiab txias hauv ib puag ncig
Lub npe rau ib yam khoom tsim nyob rau hauv cov tshuaj tiv thaiv tshuaj yog dab tsi?
Cov tshuaj tiv thaiv tshuaj yog cov txheej txheem uas cov atoms tam sim no nyob rau hauv cov tshuaj pib rov ua kom muab cov tshuaj sib xyaw tshiab tam sim no hauv cov tshuaj tsim los ntawm cov tshuaj tiv thaiv. Cov tshuaj pib ntawm cov tshuaj tiv thaiv tshuaj hu ua reactants, thiab cov tshuaj tshiab uas tshwm sim hu ua cov khoom
Yuav ua li cas tshwm sim rau atoms nyob rau hauv cov tshuaj tiv thaiv raws li Dalton lub atomic txoj kev xav?
Dalton's Atomic Theory Tag nrho cov atoms ntawm ib lub caij yog tib yam. Cov atoms ntawm cov ntsiab lus sib txawv sib txawv hauv qhov loj thiab loj. Cov tshuaj yog tsim los ntawm kev sib txawv ntawm cov lej sib txawv ntawm cov atoms. Cov tshuaj tiv thaiv tshuaj ua rau muaj kev hloov pauv ntawm cov atoms hauv cov reactant thiab cov khoom sib txuas
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
