Ib endothermic tshuaj tiv thaiv yog ib qho tshuaj tiv thaiv uas absorbs cua sov los ntawm nws ib puag ncig. Lub zog absorbed muab lub zog ua kom lub zog tshuaj tiv thaiv tshwm sim.
Hais txog qhov no, puas yog tag nrho cov tshuaj tiv thaiv endothermic lossis exothermic?
Tag nrho cov tshuaj tiv thaiv koom nrog kev hloov ntawm lub zog. Endothermic Cov txheej txheem yuav tsum muaj kev nkag siab ntawm lub zog los mus txuas ntxiv thiab tau pom zoo los ntawm kev hloov pauv zoo hauv enthalpy. Exothermic Cov txheej txheem tso tawm lub zog thaum ua tiav, thiab tau qhia los ntawm kev hloov pauv tsis zoo hauv enthalpy.
Qhov thib ob, qhov twg ntawm cov tshuaj tiv thaiv yog cov tshuaj tiv thaiv endothermic? Cov tshuaj tiv thaiv kab mob endothermic yog tshuaj cov tshuaj tiv thaiv nyob rau hauv uas cov reactants nqus cua sov lub zog los ntawm ib puag ncig los tsim cov khoom.
Ua li cas Endothermic thiab Exothermic Reactions txawv?
| Endothermic Reaction | Exothermic Reaction |
|---|---|
| Enthalpy hloov (ΔH) yog qhov zoo | ΔH yog qhov tsis zoo |
Ua raws li qhov xav tau, qhov hloov pauv endothermic yog dab tsi?
Lub ntsiab txhais ntawm endothermic yog tshuaj lom neeg cov tshuaj tiv thaiv uas yog nrog los ntawm kev nqus cua sov, los yog ib yam kab mob uas tsim kom muaj cua sov los tswj nws qhov kub thiab txias. Ib qho tshuaj tiv thaiv uas ua haujlwm tsuas yog thaum tshav kub absorbed yog ib qho piv txwv ntawm cov tshuaj tiv thaiv uas yuav piav raws li endothermic.
Kev hloov pauv endothermic thiab exothermic yog dab tsi?
Exothermic - lo lus piav qhia txog tus txheej txheem uas tso tawm lub zog hauv daim ntawv ntawm tshav kub. Exothermic Cov tshuaj tiv thaiv feem ntau hnov kub vim nws muab cua sov rau koj. Endothermic - cov txheej txheem los yog cov tshuaj tiv thaiv uas absorbs lub zog nyob rau hauv daim ntawv ntawm tshav kub. Txhaum ib daim ntawv cog lus tshuaj yuav tsum muaj zog thiab yog li ntawd Endothermic.
Pom zoo:
Puas yog cov tshuaj tiv thaiv tom ntej endothermic lossis exothermic?
Cov tshuaj tiv thaiv pem hauv ntej muaj ΔH>0. Qhov no txhais tau tias cov tshuaj tiv thaiv pem hauv ntej yog endothermic. Yog li ntawd, cov tshuaj tiv thaiv yuav tsum tau beexothermic
Puas yog cov tshuaj tiv thaiv combustion exothermic lossis endothermic?
Combustion yog ib qho oxidation cov tshuaj tiv thaiv uas ua rau kub, thiab nws yog li ntawd ib txwm exothermic. Tag nrho cov tshuaj tiv thaiv ua ntej tawg cov ntawv cog lus thiab tom qab ntawd ua cov tshiab los tsim cov ntaub ntawv tshiab. Kev rhuav tshem cov ntawv cog lus siv lub zog thaum ua cov ntawv cog lus tshiab tso tawm lub zog
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
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
