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.
