Yog tias cov tshuaj tiv thaiv tom ntej yog exothermic qhov rov qab cov tshuaj tiv thaiv yuav yog endothermic, thiab yog tias cov tshuaj tiv thaiv tom ntej yog endothermic qhov rov qab cov tshuaj tiv thaiv yuav exothermic. Cov tshuaj tiv thaiv uas ua rau tsis muaj qhov hloov pauv ntawm qhov kub thiab txias hauv lub thawv insulated tau hais tias yog athermal.
Yuav ua li cas thaum cov tshuaj tiv thaiv exothermic thim rov qab?
Yog tias qhov kev hloov pauv hloov tau yog exothermic (muab tawm lub zog) nyob rau hauv ib qho kev taw qhia nws yog endothermic (siv lub zog) nyob rau hauv lwm txoj kev. Thaum cov tshuaj tiv thaiv thim rov qab tau tshwm sim nyob rau hauv lub kaw lus kaw qhov sib npaug yuav mus txogQhov no txhais tau hais tias cov kev cuam tshuam rau pem hauv ntej thiab rov qab tshwm sim ntawm tib tus nqi.
Puas yog cov tshuaj tiv thaiv exothermic thim rov qab lossis hloov tsis tau?
Rau qhov kev hloov pauv tau, txawm tias qhov kev xa mus los yog rov qab cov tshuaj tiv thaiv yuav yog exothermic, thiab lwm qhov yuav ua rau endothermic. Thaum peb nce qhov kub thiab txias, cov tshuaj tiv thaiv yuav nyiam qhov twg cov tshuaj tiv thaiv endothermic kom sov thiab txo qhov kub.
Puas yog cov tshuaj tiv thaiv exothermic rau pem hauv ntej lossis thim rov qab?
Nco ntsoov tias ib qho kev taw qhia ntawm cov tshuaj tiv thaiv ib txwm yog exothermic thiab lwm qhov kev taw qhia yog endothermic. Cov kev taw qhia endothermic muaj lub zog ua kom loj dua. Thaum kub nce, ob qho tib si tus nqi (rau pem hauv ntej thiab rov qab) nce tab sis tus nqi ntawm cov tshuaj tiv thaiv endothermic nce ntxiv!
Yuav ua li cas thaum koj tshem tawm cov cua sov los ntawm cov tshuaj tiv thaiv exothermic?
Yog tias cov tshuaj tiv thaiv yog exothermic thiab koj tshem tawm cov cua sov, lub kaw lus yuav sim hloov cov cua sov ploj. Txoj hauj lwm ntawm equilibrium yuav hloov mus rau sab xis. Yog tias koj ntxiv cov cua sov, lub kaw lus yuav sim tshem tawm cov cua sov. Txoj hauj lwm ntawm qhov sib npaug yuav hloov mus rau sab laug.
