Ib qho tshuaj tiv thaiv exothermic tshwm sim thaum qhov kub ntawm qhov system nce vim qhov hloov pauv ntawm cov cua sovCov cua sov no tau tso rau hauv ib puag ncig, ua rau tag nrho qhov tsis zoo rau cov cua sov ntawm cov tshuaj tiv thaiv (qrxn<0). … Cov enthalpies ntawm cov tshuaj tiv thaiv no tsawg dua xoom, thiab yog li ntawd yog exothermic tshua.
txheej txheem exothermic tshwm sim li cas?
Cov tshuaj tiv thaiv uas tso tawm lub zog hu ua exothermic. Hauv cov tshuaj tiv thaiv exothermic,ntau lub zog raug tso tawm thaum cov ntawv cog lus tsim nyob rau hauv cov khoom dua li siv los rhuav tshem cov ntawv cog lus hauv cov reactantsCov tshuaj tiv thaiv exothermic yog nrog los ntawm qhov nce ntawm qhov kub ntawm cov tshuaj tiv thaiv sib tov.
Yuav ua li cas cov tshuaj tiv thaiv exothermic pib?
Thaum muaj tshuaj lom neeg tshwm sim, zog xa mus rau lossis los ntawm ib puag ncig. Thaum lub zog hloov mus rau ib puag ncig, qhov no yog hu ua exothermic cov tshuaj tiv thaiv, thiab qhov kub thiab txias ntawm ib puag ncig nce.
Koj paub li cas cov tshuaj tiv thaiv exothermic tshwm sim?
Yog hais tias lub zog ntawm cov reactants siab tshaj lub zog ntawm cov khoom, cov tshuaj tiv thaiv yog exothermic (lub zog tau raug tso tawm thaum lub sij hawm cov tshuaj tiv thaiv). Yog hais tias lub zog theem ntawm cov khoom yog siab tshaj lub zog theem ntawm cov reactants nws yog endothermic cov tshuaj tiv thaiv.
Yuav ua li cas cov tshuaj tiv thaiv exothermic tso cua sov?
Cov tshuaj tiv thaiv kab mob sib kis hloov tshuaj lub zog (enthalpy) hauv cov tshuaj lom neeg rau hauv lub zog cua sov. Lub zog tshuaj txo qis, thiab lub zog cua sov nce (tag nrho lub zog yog kev txuag). … BOND MAKING TSO ENERGY, TIV THAIV TIV THAIV TIV THAIV, yog li ntawm kev ua daim ntawv cog lus, lub zog hluav taws xob tso tawm.
