Fission yog tus txheej txheem thaum ib qho tsis ruaj khov thiab loj lub nuclei disintegrate los tsim ntau lub nuclei me. Ib qho zoo piv txwv ntawm a fission cov tshuaj tiv thaiv yog lub nuclear fais fab nroj tsuag. Nyob rau hauv ib tug nuclear fais fab nroj tsuag, no tshav kub generated thaum lub sij hawm fission yog hloov dua siab tshiab rau hluav taws xob hluav taws xob rau peb siv hauv tsev thiab chaw tsim khoom.
Ib yam li ib tug yuav nug, qhov piv txwv ntawm fission yog dab tsi?
Fission yog qhov sib cais ntawm ib qho atomic nucleus rau hauv ob lossis ntau dua sib zog nuclei nrog lub zog tso tawm. Rau piv txwv , cov fission ntawm ib kilogram ntawm uranium tso tawm ntau npaum li lub zog li hlawv ib ncig ntawm plaub billion kilograms ntawm thee.
Ib yam li ntawd, nuclear fusion muab piv txwv li cas? Nuclear fusion yog thaum ob los yog ntau tshaj lub teeb yuag atom koom ua ke los tsim ib hnyav dua nucleus, nrog txhua lub zog tso tawm vim kev hloov pauv hloov mus rau hauv nuclear zog. Ib qho piv txwv ntawm nuclear fusion yog cov txheej txheem ntawm plaub hydrogens los ua ke los tsim helium.
Tsuas yog li ntawd, fission siv li cas hauv lub neej txhua hnub?
Lub tshav kub ntawm lub reactor yog siv kom sov dej thiab chav tsav turbine. Feem ntau cov reactors ua haujlwm ntawm lub hauv paus ntsiab lus ntawm fission .. Uranium 235 los yog plutonium yog siv raws li roj nyob rau hauv lub reactor. Tom qab ntawd thaum cov tswj rods yog lifted fission hnub qub thiab ua kom sov.
Fission Reaction yog dab tsi?
Hauv nuclear physics thiab nuclear chemistry, nuclear fission yog nuclear tshuaj tiv thaiv los yog cov txheej txheem radioactive decay nyob rau hauv uas lub nucleus ntawm ib tug atom splits rau hauv ob los yog ntau dua me me, sib zog nuclei. Fission yog ib daim ntawv ntawm nuclear transmutation vim hais tias qhov tshwm sim fragments tsis zoo ib yam li cov thawj atom.

Ib qho piv txwv ntawm kev sib koom ua ke hauv lub neej txhua hnub yog dab tsi?
Cohesion yog lub sij hawm rau molecules ntawm ib yam khoom ua ke. Ib qho piv txwv zoo tshaj plaws yog dej hlaws rau ntawm qhov chaw hydrophobic. Xav txog dab tsi tshwm sim thaum koj poob ib kawg ntawm ib daim ntawv phuam rau hauv ib khob dej
Thaum lub ntim ntawm ib qho piv txwv ntawm cov pa roj yog txo lub siab ntawm cov qauv ntawm cov pa roj?
Kev txo qis Cov pa roj sib xyaw txoj cai hais tias lub siab ntawm cov pa roj yog inversely cuam tshuam nrog lub ntim thiab ncaj qha ntsig txog qhov kub thiab txias. Yog tias qhov kub thiab txias yog nyob tas li, qhov sib npaug raug txo rau Boyle txoj cai. Yog li ntawd, yog tias koj txo qhov siab ntawm cov roj av tas li, nws qhov ntim yuav nce ntxiv
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Dab tsi yog qee qhov piv txwv ntawm lub neej tiag tiag ntawm cov haujlwm linear?
Teb Chaws Keeb Kwm: Ib tug neeg puas tuaj yeem muab rau kuv ua piv txwv ntawm kev ua haujlwm ntawm lub neej tiag tiag? Linear functions tshwm sim txhua lub sij hawm koj muaj qhov hloov pauv tas li. Cov piv txwv ntawm lub neej tiag tiag yog: Nrhiav tam sim no noj nyob rau hnub 1,2,3… Koj nqa tsheb mus xauj. Koj tab tom tsav tsheb ntawm qhov ceev ntawm 60 km / h
Dab tsi yog qhov txawv ntawm keeb kwm ntawm lub neej thiab lub neej voj voog?
Lub neej keeb kwm yog kev tshawb fawb txog kev xeeb tub cov tswv yim thiab cov yam ntxwv. Piv txwv ntawm lub neej keeb kwm zoo muaj xws li hnub nyoog ntawm thawj kev yug me nyuam, lifespan, thiab tus naj npawb vs loj ntawm cov xeeb ntxwv. Lub neej voj voog ntawm hom yog tag nrho ntawm cov theem thiab tsim cov kab mob mus dhau nws txoj sia
