Ib qho txheej txheem exothermic yog ib qho uas ua kom sov. Qhov cua sov no yog pauv mus rau ib puag ncig. Cov txheej txheem endothermic yog ib qho uas cov cua sov yuav tsum tau nkag mus rau lub kaw lus los ntawm ib puag ncig. Cov txheej txheem thermoneutral yog ib qho uas tsis tas yuav tsum tau cua sov los ntawm ib puag ncig los yog muab lub zog tawm mus rau ib puag ncig.
Cov tshuaj tiv thaiv kab mob endothermic thiab exothermic yog dab tsi?
Cov tshuaj tiv thaiv kab mob tsis zoo hloov lub zog mus rau ib puag ncigthiab qhov kub ntawm ib puag ncig nce. Cov tshuaj tiv thaiv endothermic coj lub zog thiab qhov kub ntawm ib puag ncig txo qis.
Qhov twg yog qhov tshuaj tiv thaiv kab mob endothermic?
Ib qho tshuaj tiv thaiv uas nqus lub zog yog hais tias yog endothermic. Hauv cov tshuaj tiv thaiv endothermic, cov khoom pib (reactants) ruaj khov dua li cov khoom; lawv nyob hauv lub xeev qis zog. Txhawm rau tsim cov khoom siv hluav taws xob ntau dua, lub zog yuav tsum tau txais los ntawm ib puag ncig.
Koj paub li cas yog qhov tshuaj tiv thaiv yog exothermic lossis endothermic?
Yog li yog tias qhov sib npaug ntawm cov enthalpies ntawm cov reactants ntau dua li cov khoom, cov tshuaj tiv thaiv yuav exothermic. Yog hais tias cov khoom sab muaj ib tug loj enthalpy, cov tshuaj tiv thaiv yog endothermic. Tej zaum koj yuav xav tias yog vim li cas cov tshuaj tiv thaiv endothermic, uas ua rau lub zog los yog enthalpy los ntawm ib puag ncig, txawm tshwm sim.
Puas yog exothermic kub lossis txias?
Ib qho exothermic txheej txheem tso cua sov, ua rau qhov kub thiab txias tam sim ntawdib puag ncig kom sawv. Cov txheej txheem endothermic absorbs cua sov thiab ua kom qhov chaw nyob ib puag ncig."
