A tshuaj tiv thaiv hauv qhov twg zog yog tso tawm mus rau ib puag ncig yog hu ua ib exothermic tshuaj tiv thaiv . Hauv hom no tshuaj tiv thaiv cov enthalpy, los yog khaws cia tshuaj zog , yog qis dua rau cov khoom lag luam dua li cov reactants. Thaum ammonium nitrate yaj hauv dej, zog yog nqus tau thiab dej txias.

Ntawm no, puas yog lub zog nqus los yog tso tawm hauv cov tshuaj tiv thaiv endothermic?

Yog li ntawd, ntau dua zog yog xav tau los rhuav cov bonds nyob rau hauv cov reactants tshaj li yog tso tawm thaum lub sij hawm tsim ntawm cov khoom. Qhov txawv hauv zog feem ntau yog nqus tau los ntawm ib puag ncig zoo li cua sov. Qhov no feem ntau ua rau txo qis ntawm qhov kub thiab txias tshuaj tiv thaiv sib tov. Tag nrho endothermic cov tshuaj tiv thaiv nqus lub zog.

Ib sab saum toj no, koj yuav ua li cas paub yog tias lub zog nqus los yog tso tawm? Yog kub yog nqus tau Thaum cov tshuaj tiv thaiv, Δ H ΔH ΔH yog qhov zoo; yog kub yog tso tawm , ces Δ H ΔH ΔH yog qhov tsis zoo.

Ib yam li ntawd, cov tshuaj tiv thaiv exothermic puas tso tawm lub zog?

Exothermic tshuaj tiv thaiv yog cov tshuaj tiv thaiv los yog txheej txheem uas tso dag zog , feem ntau yog nyob rau hauv daim ntawv ntawm tshav kub los yog lub teeb. Hauv ib exothermic tshuaj tiv thaiv , zog yog tso tawm vim tag nrho zog ntawm cov khoom yog tsawg tshaj li tag nrho zog ntawm cov reactants.

Dab tsi lub zog yog absorbed nyob rau hauv cov txheej txheem hom tshuaj tiv thaiv yog nws?

txheej txheem endothermic
