Hauv txoj kev yooj yim, cov tshuaj tiv thaiv endothermic nqus lub zog los ntawm ib puag ncig, uas yog nyob rau hauv daim ntawv ntawm tshav kub. Txawm li cas los xij, cov tshuaj tiv thaiv exothermic tso lub zog rau hauv ib puag ncig ntawm qhov system. Photosynthesis yog ib qho piv txwv nrov ntawm cov tshuaj tiv thaiv kab mob endothermic.
Dab tsi yog qhov txawv ntawm qhov kev ntsuas exothermic thiab endothermic cov lus nug?
Cov tshuaj tiv thaiv uas tso tawm lub zog, feem ntau yog ua kom sov. … Ib qho cov tshuaj tiv thaiv exothermic tso tawm lub zog thiab hnov tsw sovthaum cov tshuaj tiv thaiv kab mob endothermic absorbs lub zog thiab xav tias txias.
Qhov txawv ntawm cov txheej txheem exothermic thiab cov tshuaj tiv thaiv yog dab tsi?
Txhua yam tshuaj tiv thaiv cuam tshuam nrog kev hloov pauv ntawm lub zog. Cov txheej txheem endothermic xav tau ib qho kev tawm tswv yim ntawm lub zog los mus ua thiab tau qhia los ntawm kev hloov pauv zoo hauv enthalpy. Cov txheej txheem exothermic tso tawm lub zog thaum ua tiav, thiab tau pom zoo los ntawm kev hloov pauv tsis zoo hauv enthalpy.
Qhov txawv ntawm qhov exothermic thiab endothermic cov tshuaj tiv thaiv hlwb yog dab tsi?
Hauv cov ntsiab lus yooj yim, cov tshuaj tiv thaiv endothermic nqus lub zog los ntawm ib puag ncig uas nyob rau hauv daim ntawv ntawm tshav kub. Thaum, cov tshuaj tiv thaiv exothermic tso tawm lub zog rau hauv ib puag ncig los ntawm qhov system.
Puas yog exothermic kub lossis txias?
Ib qho exothermic txheej txheem tso cua sov, ua rau qhov kub thiab txias ntawm ib puag ncig tam sim ntawd nce. Cov txheej txheem endothermic absorbs cua sov thiab ua kom qhov chaw nyob ib puag ncig."
