Ib endothermic txheej txheem yog ib yam txheej txheem uas yuav tsum tau los yog absorbs lub zog ntawm nws ib puag ncig, feem ntau nyob rau hauv daim ntawv ntawm tshav kub. Qhov opposite ntawm ib endothermic txheej txheem yog ib exothermic txheej txheem, ib qho uas tso tawm, "muab tawm" lub zog nyob rau hauv daim ntawv ntawm tshav kub.
Thiab cov lus nug yog, dab tsi yog lub ntsiab lus ntawm exothermic thiab endothermic?
Exothermic - lo lus piav qhia txog tus txheej txheem uas tso tawm lub zog hauv daim ntawv ntawm tshav kub. Exothermic Cov tshuaj tiv thaiv feem ntau hnov kub vim nws muab cua sov rau koj. Endothermic - cov txheej txheem los yog cov tshuaj tiv thaiv uas absorbs lub zog nyob rau hauv daim ntawv ntawm tshav kub. Txhaum ib daim ntawv cog lus tshuaj yuav tsum muaj zog thiab yog li ntawd Endothermic.
Kuj Paub, txhais li cas los ntawm exothermic cov tshuaj tiv thaiv? Kev tawg nuclear yog ib qho piv txwv ntawm ib qho (siab heev) exothermic tshuaj tiv thaiv . Exothermic tshuaj tiv thaiv yog cov tshuaj tiv thaiv uas tso tawm lub zog rau hauv ib puag ncig hauv daim ntawv ntawm tshav kub. Exothermic tshuaj tiv thaiv hnov sov los yog kub los yog tej zaum yuav tawg. Ntau lub zog raug tso tawm ua cov khoom siv tshuaj lom neeg ntau dua li siv los rhuav tshem lawv.
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog endothermic thiab exothermic cov tshuaj tiv thaiv muab piv txwv?
Cov Ntsiab Lus Tseeb. Endothermic thiab exothermic cov tshuaj tiv thaiv yog tshuaj cov tshuaj tiv thaiv uas nqus thiab tso cua sov, feem. Ib qho zoo piv txwv ntawm endothermic cov tshuaj tiv thaiv yog photosynthesis. Combustion yog ib qho piv txwv ntawm cov tshuaj tiv thaiv exothermic . categorization ntawm a tshuaj tiv thaiv as endo- los yog exothermic nyob ntawm qhov kub hloov pauv.
Ib qho piv txwv ntawm endothermic yog dab tsi?
Cov no piv txwv tuaj yeem sau ua tshuaj lom neeg, tab sis feem ntau suav tias yog endothermic los yog cov txheej txheem kub-absorbing: Melting ice cubes. Melting khoom ntsev. Evaporating kua dej. Hloov Frost rau dej vapor (melting, boiling, thiab evaporation, feem ntau, yog endothermic txheej txheem.

Yuav ua li cas koj twv seb qhov kev tshwm sim yog endothermic los yog exothermic?
Yog hais tias lub zog theem ntawm cov reactants siab tshaj lub zog theem 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 ib tug endothermic cov tshuaj tiv thaiv
Thaum ib yam dab tsi txias yog endothermic los yog exothermic?
Cov tshuaj tiv thaiv endothermic yog qhov tsis sib xws. Qhov no yog thaum cov tshuaj tiv thaiv pib txias dua thiab xaus rau kub, noj lub zog los ntawm qhov pib mus rau qhov kawg. Hauv cov tshuaj tiv thaiv endothermic, lub kaw lus nce cua sov thaum ib puag ncig txias. Nyob rau hauv ib qho exothermic cov tshuaj tiv thaiv, lub kaw lus poob cua sov thaum ib puag ncig cua sov
Yuav ua li cas yog endothermic thiab exothermic cov tshuaj tiv thaiv nyob rau hauv daim duab lub zog?
Nyob rau hauv cov ntaub ntawv ntawm endothermic cov tshuaj tiv thaiv, cov reactants nyob rau hauv qis zog theem piv rau cov khoom - raws li qhia nyob rau hauv lub zog daim duab hauv qab no. Nyob rau hauv cov ntaub ntawv ntawm ib tug exothermic cov tshuaj tiv thaiv, cov reactants yog nyob rau hauv ib tug siab zog theem piv rau cov khoom, raws li qhia hauv qab no nyob rau hauv lub zog daim duab
Puas yog boiling kua endothermic los yog exothermic?
Teb thiab piav qhia: Boiling yog ib qho endothermic cov tshuaj tiv thaiv los yog txheej txheem thaum tshav kub tau muab rau thiab absorbed los ntawm cov kua system boiled
Dab tsi yog qhov txawv ntawm Arrhenius txhais thiab brønsted Lowry txhais ntawm acids thiab bases?
Qhov txawv ntawm peb txoj kev xav yog qhov kev xav Arrhenius hais tias cov kua qaub ib txwm muaj H + thiab cov hauv paus ib txwm muaj OH-. Thaum tus qauv Bronsted-Lowry thov tias cov kua qaub yog cov neeg pub dawb proton thiab cov neeg txais kev lees paub yog li cov hauv paus tsis tas yuav muaj OH- yog li cov kua qaub pub ib qho proton rau dej tsim H3O +
