Exothermic cov tshuaj tiv thaiv Nyob rau hauv cov tshuaj tiv thaiv exothermic, tag nrho lub zog ntawm cov khoom yog tsawg dua tag nrho lub zog ntawm cov reactants. Yog li, qhov kev hloov pauv hauv enthalpy yog qhov tsis zoo, thiab cua sov tawm mus rau ib puag ncig.
Yuav ua li cas rau lub zog cua sov hauv cov tshuaj tiv thaiv exothermic?
Ib txheej txheem exothermic tso cua sov, ua rau qhov kub thiab txias ntawm ib puag ncig tam sim ntawd nce. Cov txheej txheem endothermic absorbs cua sov thiab ua kom qhov chaw nyob ib puag ncig."
Lub zog cua sov tuaj qhov twg los ntawm qhov kev tawm tsam sab nraud?
Lub zog hluav taws xob hluav taws xob tuaj yeem los ntawm qhov twg? Cov cua sov los ntawm lub zog khaws cia hauv cov khoom siv tshuaj lom neeg ntawm cov tshuaj reactant molecules--uas yog ntau dua li lub zog khaws cia hauv cov khoom sib txuas ntawm cov khoom molecules.
Cov tshuaj tiv thaiv twg yog qhov cua sov sab nraud?
Ib qho tshuaj tiv thaiv exothermic yog "kev tshwm sim uas tag nrho cov qauv enthalpy hloov ΔH⚬ yog qhov tsis zoo." Exothermic cov tshuaj tiv thaiv feem ntau tso cov cua sov thiab ua kom hloov cov ntawv cog lus tsis muaj zog nrog cov muaj zog dua.
Vim li cas cov cua sov hloov zuj zus thaum muaj kev kub ntxhov?
Cov tshuaj tiv thaiv hluav taws xob hloov hluav taws xob hluav taws xob (enthalpy) hauv cov tshuaj mus rau hauv lub zog hluav taws xob. Lub tshuaj zog txo qis, thiab lub zog cua sov nce (tag nrho lub zog yog txuag). … BOND MAKING RELEASES ENERGY, RAWS LI YUAV TSUM TAU TXAIS, yog li qhov tshwm sim ntawmkev ua lag luam, lub zog hluav taws xob tso tawm.

Lub sijhawm tag nrho kev kub ntxhov ntawm peb mais ko taw?
Peb mais Island kev huam yuaj yog ib nrab meltdown ntawm reactor tooj 2 ntawm Three Mile Island Nuclear Generating Station (TMI-2) hauv Dauphin County, Pennsylvania, ze Harrisburg, thiab Tom qab cov hluav taws xob xau uas tshwm sim rau lub Peb Hlis 28, 1979.
Lub sijhawm kuv lub sijhawm dawb lossis thaum kuv lub sijhawm dawb?
yog li, qhov no txhais tau tias "thaum kuv lub sijhawm dawb" tsis siv ntauthiab koj muab "hauv kuv lub sijhawm dawb" ntau dua nyob rau qhov kawg ntawm kab lus. Piv txwv li: Kuv tau taug kev tus dev thaum kuv lub sijhawm dawb.
Lub sijhawm kav bindusara muaj kev kub ntxhov ntawm?
Thaum Bindusara ua vajntxwv kav cov pejxeem Taxila, sực tiết từ người mẫn quyền bài hát Bindusara. Raws li kev tsis sib haum xeeb hauv lub nceeg vaj, Nanda tau tawm haujlwm thiab ploj mus rau hauv kev ntiab tawm. Lub peev ntawm Maurya Empire nyob qhov twg?
Thaum lub sijhawm ntsuas qhov sib npaug ntawm qhov ntsuas cua sov yog nyob rau hauv kev sib cais?
Los ntawm txoj cai thib ob ntawm thermodynamics: Txoj cai thib ob ntawm thermodynamics hais tias qhov entropy ntawm ib qho cais qhov system yeej tsis txo qis, vim tias cov tshuab cais ib txwm hloov mus rau qhov sib npaug ntawm qhov ntsuas kub, lub xeev nrog siab kawg entropy.
Puas pab cua sov zoo ib yam li kub kub thaum muaj xwm ceev?
Pab cov cua sov tig rau automaticallytxhawm rau pab kom sov koj lub tsev sai dua yog tias qhov kub thiab txias poob sai sai. Qhov chaw kub kub thaum muaj xwm txheej kub ntxhov yuav tsum tau hloov los ntawm tes thiab yuav tsum tsuas yog siv rau qhov kub qis dua 30 degrees.
