Ib txheej txheem endothermic yog ib qho 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. Tej zaum nws yuav yog tshuaj txheej txheem , xws li dissolving ammonium nitrate hauv dej, los yog lub cev txheej txheem , xws li melting ntawm ice cubes.
Ib yam li ntawd, cov txheej txheem twg yog exothermic?
Exothermic - lo lus piav qhia a txheej txheem uas tso tawm lub zog nyob rau hauv daim ntawv ntawm tshav kub. Tsim cov tshuaj bondreleases zog thiab yog li ntawd yog ib qho txheej txheem exothermic . Exothermic Cov tshuaj tiv thaiv feem ntau hnov kub vim nws muab cua sov rau koj. Endothermic - ib txheej txheem los yog cov tshuaj tiv thaiv uas nqus lub zog nyob rau hauv daim ntawv ntawm tshav kub.
Kuj Paub, yog vim li cas melting txheej txheem endothermic? Yuav kom tau txais nws mus rau lub xeev, koj yuav tsum muab cov khoom siv zog. Melting tsuas yog qhov ntawd. Thaum ib yam dab tsi yaj , nws tau txais lub zog. Qhov tseem ceeb, lub cev txheej txheem ntawm yaj yog endothermic , vim hais tias lub zog yuav tsum tau hloov cov khoom ua kua.
Xav txog qhov no, dab tsi yog cov txheej txheem endothermic thiab exothermic?
Ib txheej txheem exothermic tso cua sov, ua rau qhov kub thiab txias ntawm ib puag ncig tam sim ntawd nce. Ib txheej txheem endothermic absorbs cua sov thiab ua kom cov puag ncig."
Dab tsi ua rau cov tshuaj tiv thaiv endothermic?
Thaum lub zog tso tawm raws li cua sov, txheej txheem isothermic, thiab thaum tshav kub absorbed, txheej txheem yog endothermic . Ib endothermic tshuaj tiv thaiv yog ib qho uas ua rau muaj qhov txo qis hauv qhov kub vim nws nqus cua sov los ntawm ib puag ncig thiab khaws lub zog hauv cov ntawv cog lus tsim hauv tshuaj tiv thaiv.

Dab tsi yog txheej txheem spontaneous thiab non-spontaneous txheej txheem?
Cov txheej txheem spontaneous yog ib qho uas tshwm sim yam tsis muaj kev cuam tshuam ntawm sab nraud. Ib txoj kev uas tsis yog tshwm sim yuav tsis tshwm sim yog tias tsis muaj kev cuam tshuam ntawm sab nraud
Thaum twg cov txheej txheem twg cov hlwb siv oxygen los tso lub zog khaws cia?
Hauv cov hlwb siv oxygen los tso tawm lub zog khaws cia hauv cov suab thaj xws li qabzib. Qhov tseeb, feem ntau ntawm lub zog siv los ntawm cov hlwb hauv koj lub cev yog muab los ntawm kev ua pa ntawm tes. Ib yam li photosynthesis tshwm sim hauv organelles hu ua chloroplasts, cellular respiration tshwm sim nyob rau hauv organelles hu ua mitochondria
Dab tsi ua rau cov txheej txheem dissolving exothermic lossis endothermic?
Cov txheej txheem ntawm dissolving yuav ua tau endothermic (kub mus down) los yog exothermic (kub mus txog). Yog tias nws siv lub zog ntau dua los cais cov khoom ntawm cov kuab tshuaj dua li tso tawm thaum cov dej molecules khi rau cov khoom, ces qhov kub thiab txias (endothermic)
