Ib endothermic cov tshuaj tiv thaiv tshwm sim thaum lub zog siv los rhuav tshem cov ntawv cog lus hauv cov reactants ntau dua li cov zog muab tawm thaum daim ntawv cog lus tau tsim hauv cov khoom. Qhov no txhais tau tias tag nrho cov tshuaj tiv thaiv coj nyob rau hauv zog , yog li ntawd muaj qhov kub thiab txias hauv ib puag ncig.
Hais txog qhov no, lub zog mus rau qhov twg hauv cov tshuaj tiv thaiv endothermic?
Hauv endothermic cov tshuaj tiv thaiv , daim ntawv cog lus energies ntawm cov reactants yog ntau dua li cov nyiaj tshuav ntawm cov khoom. Yog li ntawd, ntau dua zog yog xav tau los rhuav tshem cov ntawv cog lus hauv cov reactants tshaj li tawm thaum lub sij hawm tsim cov khoom. Qhov txawv hauv zog feem ntau yog absorbed los ntawm ib puag ncig raws li cua sov.
Ib sab saum toj no, ua li cas rau lub zog thaum muaj tshuaj tiv thaiv? Tag nrho tshuaj tiv thaiv koom nrog zog . Zog yog siv los rhuav cov ntawv cog lus hauv reactants, thiab zog raug tso tawm thaum daim ntawv cog lus tshiab tsim hauv cov khoom. Endothermic cov tshuaj tiv thaiv nqus zog , thiab exothermic cov tshuaj tiv thaiv tso tawm zog . Txoj cai ntawm kev txuag ntawm zog hais tias qhov teeb meem tsis tuaj yeem tsim lossis rhuav tshem.
Tom qab ntawd, yuav ua li cas rau qhov kub thiab txias thaum lub sij hawm cov tshuaj tiv thaiv endothermic?
Ib endothermic cov tshuaj tiv thaiv tshwm sim thaum lub kub ntawm ib qho kev sib cais txo qis thaum ib puag ncig ntawm ib qho kev tsis sib cais tau txais cua sov. Cov tshuaj tiv thaiv kab mob endothermic ua rau tag nrho qhov zoo kub ntawm tshuaj tiv thaiv (qrxn>0).
Puas endothermic nce lossis poob zog?
Exothermic txhais tau hais tias thaum lub sij hawm cov tshuaj tiv thaiv, molecules tau tsiv los ntawm lub xeev siab dua zog mus rau lub xeev qis. Ib endothermic cov tshuaj tiv thaiv yog qhov opposite. Hauv ib endothermic tshuaj tiv thaiv, qhov system tau txais cua sov li ib puag ncig txias. Nyob rau hauv ib tug exothermic tshuaj tiv thaiv, lub system poob cua sov li ib puag ncig cua sov.

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
Yuav ua li cas rau lub zog nyob rau hauv ib tug exothermic tshuaj tiv thaiv?
Cov tshuaj tiv thaiv exothermic tshwm sim thaum lub zog siv los rhuav tshem cov ntawv cog lus hauv cov reactants (cov khoom pib) tsawg dua lub zog tso tawm thaum cov nyiaj tshiab tau tsim nyob rau hauv cov khoom (cov khoom koj xaus nrog). Combustion yog ib qho piv txwv ntawm cov tshuaj tiv thaiv exothermic - koj tuaj yeem hnov cov cua sov uas tau muab tawm yog tias koj nyob ze dhau
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 tshwm sim rau atoms nyob rau hauv cov tshuaj tiv thaiv raws li Dalton lub atomic txoj kev xav?
Dalton's Atomic Theory Tag nrho cov atoms ntawm ib lub caij yog tib yam. Cov atoms ntawm cov ntsiab lus sib txawv sib txawv hauv qhov loj thiab loj. Cov tshuaj yog tsim los ntawm kev sib txawv ntawm cov lej sib txawv ntawm cov atoms. Cov tshuaj tiv thaiv tshuaj ua rau muaj kev hloov pauv ntawm cov atoms hauv cov reactant thiab cov khoom sib txuas
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
