C. Cov cua sov tib yam yuav raug tso tawm thaum lub tshuab ua kua ua kua dej , ntawm 100 deg. C. Yog li, nws yog txheej txheem anexothermic, thiab tso tawm cov caloric npaum li cas ntawm Latent Heatof Vaporization rau qhov loj ntawm chav uas condenses.
Kuj paub yog, yog condensing endothermic los yog exothermic?
Evaporation yog endothermic , txhais tau tias nws yuav siv cua sov los ntawm nws ib puag ncig. Condensation txawm li cas los xij, yog theopposite nrog nws ua exothermic , qhov twg nws tso cua sov rau ib puag ncig.
Ib tug kuj yuav nug, yog dej tig mus rau chav exothermic? Thaum twg chav , uas yog gaseous dej , condenses, cua sov tawm. Es tsis txhob, nws yog khaws cia los ntawm gaseous dej molecules. Thaum cov molecules condense rau formliquid dej dua, lub zog muab tso rau hauv lub system yuav tsum bereleased. Thiab qhov no cia lub zog yog tso tawm raws li exothermic kub.
Tsis tas li ntawd, yog vim li cas condensing chav exothermic?
Ib exothermic cov tshuaj tiv thaiv ua rau lub zog kub. Condensation yog cov txheej txheem uas dej vapor hloov mus rau hauv dej. Qhov no feem ntau tshwm sim thaum dej vapor molecules tuaj rau hauv kev sib cuag nrog cov molecules txias. Qhov no ua rau cov dej vapormolecules poob qee lub zog raws li cua sov.
Puas yog kub kub endothermic lossis exothermic?
Endo txhais tau tias "hauv" thaum exo txhais tau tias "sab nraum". Yog li ntawd, endothermic cov tshuaj tiv thaiv cua sov los ntawm lawv ib puag ncig (xws li dej khov yaj thiab "txias" dej haus). Hloov pauv, exothermic cov tshuaj tiv thaiv tso cua sov rau lawv ib puag ncig (piv txwv li. kub ntoo hauv qhov cub).

Puas yog qhov kub ntawm kev daws rau LiCl exothermic lossis endothermic?
Teb thiab piav qhia: Lub tshav kub ntawm kev daws rau LiCl yog exothermic. Thaum lithium thiab chloride ionize hauv dej, lawv yuav tsum xub sib cais los ntawm ib leeg
Puas yog cov tshuaj tiv thaiv tom ntej endothermic lossis exothermic?
Cov tshuaj tiv thaiv pem hauv ntej muaj ΔH>0. Qhov no txhais tau tias cov tshuaj tiv thaiv pem hauv ntej yog endothermic. Yog li ntawd, cov tshuaj tiv thaiv yuav tsum tau beexothermic
Puas yog cov tshuaj tiv thaiv combustion exothermic lossis endothermic?
Combustion yog ib qho oxidation cov tshuaj tiv thaiv uas ua rau kub, thiab nws yog li ntawd ib txwm exothermic. Tag nrho cov tshuaj tiv thaiv ua ntej tawg cov ntawv cog lus thiab tom qab ntawd ua cov tshiab los tsim cov ntaub ntawv tshiab. Kev rhuav tshem cov ntawv cog lus siv lub zog thaum ua cov ntawv cog lus tshiab tso tawm lub zog
Puas yog chav condensing endothermic lossis exothermic?
C. Cov cua kub tib yam yuav raug tso tawm thaum lub chav condenses rau cov dej ua kua, ntawm 100 deg. C. Yog li, nws yog txheej txheem exothermic, thiab tso tawm cov caloric npaum li cas ntawm Latent Thaum tshav kub kub ntawm Vaporization rau qhov loj ntawm chav uas condenses
Puas yog Melting endothermic lossis exothermic?
Melting yog cov tshuaj tiv thaiv endothermic uas tag nrho cov cua sov hauv cov khoom, tseem hu ua enthalpy, nce
