Tshuaj tiv thaiv tuaj yeem muab cais ua exothermic lossis endothermic. Ib qho exothermic tshuaj tiv thaiv tso tawm lub zog rau hauv nws ib puag ncig. Ib qho endothermic tshuaj tiv thaiv , ntawm qhov tod tes, nqus lub zog los ntawm nws ib puag ncig hauv daim ntawv ntawm kub.
Yog li ntawd, dab tsi yog cov tshuaj tiv thaiv uas absorbs tshav kub hu ua?
Teb thiab piav qhia: A tshuaj tiv thaiv uas absorbs tshav kub yog hu ua ib qho endothermic tshuaj tiv thaiv . Yog vim li cas tshuaj tiv thaiv absorbs tshav kub muaj feem xyuam rau lub xeev lub zog kawg
Tsis tas li ntawd, qhov nqus cua sov yog dab tsi? adj (ntawm ib qho tshuaj tiv thaiv los yog compound) tshwm sim los yog tsim nrog nqus ntawm kub . Synonyms: endothermal, endothermic endoergic, zog- nqus tau . (ntawm cov tshuaj tiv thaiv nuclear) tshwm sim nrog nqus ntawm lub zog. decalescent. absorbing cua sov tsis muaj qhov kub thiab txias thaum rhuab tshaj ib qho taw tes.
Nyob rau hauv no hais txog, yog vim li cas yog tshav kub tso tawm los yog absorbed nyob rau hauv ib tug tshuaj tiv thaiv?
Qhov sib txawv ntawm enthalpy ntawm cov reactants thiab cov khoom yog sib npaug ntawm lub zog nqus tau los ntawm ib puag ncig. Vim cov tshuaj tiv thaiv tso tawm los yog nqus lub zog, lawv cuam tshuam qhov kub ntawm lawv ib puag ncig. Exothermic tshuaj tiv thaiv kub nce lawv ib puag ncig thaum endothermic cov tshuaj tiv thaiv txias lawv.
Cov txheej txheem twg absorbs zog?
Qhov opposite ntawm ib tug exothermic txheej txheem yog endothermic txheej txheem , ib o absorbs zog nyob rau hauv daim ntawv ntawm tshav kub. Lub tswvyim yog nquag siv nyob rau hauv lub cev sciences rau cov tshuaj tiv thaiv, qhov twg raws li nyob rau hauv chemical bond zog uas yuav hloov dua siab tshiab rau thermal zog (kub).

Dab tsi yog plaub yam sib txawv uas tuaj yeem cuam tshuam tus nqi ntawm cov tshuaj tiv thaiv?
Reactant concentration, lub cev lub cev ntawm cov reactants, thiab cheeb tsam saum npoo, qhov kub thiab txias, thiab muaj cov catalyst yog plaub yam tseem ceeb uas cuam tshuam rau cov tshuaj tiv thaiv
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
Qhov kev sib npaug twg yog qhov tsim nyog los suav cov cua sov uas tsim los ntawm HCl NaOH cov tshuaj tiv thaiv?
Xam cov naj npawb ntawm moles ntawm lub hauv paus koj ntxiv los txiav txim siab molar tshav kub ntawm qhov nruab nrab, qhia siv qhov sib npaug Δ H = Q ÷ n, qhov twg 'n' yog tus naj npawb ntawm moles. Piv txwv li, xav tias koj ntxiv 25 mL ntawm 1.0 M NaOH rau koj HCl los ua kom muaj cua sov ntawm nruab nrab ntawm 447.78 Joules
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
