Thaum tsim cov ntawv cog lus tshwm sim ntawm ob lub atoms, vim yog cov tshuaj tiv thaiv ua rau lub peev xwm ntawm cov atoms ploj uas tau hloov mus ua tshuab hluav taws xob nyob rau hauv daim ntawv ntawm tshav kub thiab lub teebCov cua sov los yog lub teeb lub zog no yog tso tawm tom qab tsim cov ntawv cog lus ua ib feem ntawm cov khoom.
Yuav ua li cas rau lub zog thaum muaj tshuaj lom neeg daim ntawv cog lus?
Cov tshuaj tiv thaiv ua rau thiab rhuav tshem cov tshuaj lom neeg ntawm cov molecules, ua rau cov ntaub ntawv tshiab raws li cov khoom ntawm cov tshuaj tiv thaiv. … Txhaum chemical bonds absorbs zog, thaum ua daim ntawv cog lus tshiab tso tawm lub zog, nrog rau tag nrho cov tshuaj tiv thaiv yog endothermic los yog exothermic.
Yuav ua li cas thaum tsim ib daim ntawv cog lus tshuaj?
Tshuaj tiv thaiv yog lub zog ntawm kev nyiam uas khi atoms ua ke. Bonds yog tsim thaum valence electrons, cov electrons nyob rau hauv lub outermost hluav taws xob "plhaub" ntawm ib tug atom, interact… element.
Puas muaj zog ntxiv thaum tsim daim ntawv cog lus?
Thaum daim ntawv cog lus muaj zog, muaj zog dua daim ntawv cog lusvim tias nws yuav siv zog ntau dua los rhuav tshem daim ntawv cog lus ruaj khov. Qhov no cuam tshuam nrog daim ntawv cog lus thiab daim ntawv cog lus ntev. Thaum daim ntawv cog lus siab dua, daim ntawv cog lus ntev dua, thiab qhov luv luv ntawm daim ntawv cog lus ntev txhais tau tias ntau dua Bond Zog vim tias muaj hluav taws xob ntau ntxiv.
Vim li cas lub zog tso tawm thaum tsim daim ntawv cog lus?
Thaum muaj tshuaj tiv thaiv, cov nyiaj sib txuas ntawm cov atoms hauv cov reactans yuav tsum tau tawg ua ntej ua ntej cov ntawv cog lus tshiab ntawm cov atoms hauv cov khoom tuaj yeem tsim.… Yog li ntawd, kev rhuav tshem daim ntawv cog lus yog ib qho kev hloov pauv. (b) Bond tsim tawm lub zog. Yog li, kev tsim daim ntawv cog lus yog ib qho txheej txheem exothermic
