Ib endothermic tshuaj tiv thaiv yog ib qho siv tshuaj zog . Lub sij hawm endothermic txheej txheem piav qhia txog txheej txheem lossis tshuaj tiv thaiv nyob rau hauv uas lub system absorbs zog los ntawm nws ib puag ncig; feem ntau, tab sis tsis tas li, hauv daim ntawv ntawm tshav kub.
Ib yam li ntawd, lub zog twg siv cov tshuaj tiv thaiv kab mob endothermic?
Ib endothermic cov tshuaj tiv thaiv yog ib o o siv tshuaj zog . Lub sij hawm endothermic txheej txheem piav qhia txog txheej txheem lossis tshuaj tiv thaiv nyob rau hauv uas lub system absorbs zog los ntawm nws ib puag ncig; feem ntau, tab sis tsis tas li, hauv daim ntawv ntawm tshav kub.
Tom qab ntawd, lo lus nug yog, dab tsi yog ob lub ntsiab lus ntawm lub zog muab tawm thaum ntawv kub hnyiab thiab lub zog los ntawm qhov twg? Tshuaj zog khaws cia rau hauv ntawv yog transformed thiab tso tawm raws li electromagnetic zog thiab thermal zog.
Ib tug kuj yuav nug, uas tshwm sim rau lub zog thaum lub sij hawm endothermic tshua?
Ib endothermic cov tshuaj tiv thaiv tshwm sim thaum tus zog siv los rhuav cov ntawv cog lus hauv cov reactants ntau dua li cov zog muab tawm thaum daim ntawv cog lus raug tsim hauv cov khoom. Qhov no txhais tau tias tag nrho cov tshuaj tiv thaiv siv hauv zog , yog li ntawd muaj qhov kub thiab txias hauv thaj chaw ib puag ncig.
Hom tshuaj tiv thaiv dab tsi tso tawm lub zog?
Ib qho exothermic tshuaj tiv thaiv yog tshuaj tshuaj tiv thaiv uas tso dag zog los ntawm lub teeb lossis cua sov. Nws yog qhov opposite ntawm endothermic tshuaj tiv thaiv.

Yuav ua li cas yog endothermic thiab exothermic cov tshuaj tiv thaiv nyob rau hauv daim duab lub zog?
Nyob rau hauv cov ntaub ntawv ntawm endothermic cov tshuaj tiv thaiv, cov reactants nyob rau hauv qis zog theem piv rau cov khoom - raws li qhia nyob rau hauv lub zog daim duab hauv qab no. Nyob rau hauv cov ntaub ntawv ntawm ib tug exothermic cov tshuaj tiv thaiv, cov reactants yog nyob rau hauv ib tug siab zog theem piv rau cov khoom, raws li qhia hauv qab no nyob rau hauv lub zog daim duab
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
Cov tshuaj tiv thaiv dab tsi yog qhov tshuaj tiv thaiv neutralization?
Neutralization yog ib hom tshuaj tiv thaiv nyob rau hauv uas muaj zog acid thiab muaj zog puag react nrog ib leeg los tsim dej thiab ntsev
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
