C. Tib qhov kub yuav raug tso tawm thaum lub steam condenses rau cov dej ua kua, ntawm 100 deg. C. Yog li, nws yog ib qho exothermic txheej txheem, thiab tso tawm cov caloric npaum li cas ntawm Latent Kub ntawm Vaporization rau qhov loj ntawm chav uas condenses.

Tib neeg kuj nug, yog vim li cas ncu condensing exothermic?

Ib exothermic cov tshuaj tiv thaiv ua rau lub zog kub. Condensation yog tus txheej txheem uas dej vapor hloov mus ua kua dej. Qhov no feem ntau tshwm sim thaum dej vapor molecules tuaj rau hauv kev sib cuag nrog txias molecules. Qhov no ua rau cov dej vapor molecules kom poob ib co zog li cua sov.

Kuj Paub, yog hlawv cawv endothermic lossis exothermic? (b) Lub tshav kub yog absorbed los ntawm isopropyl cawv kom tau evaporated ntawm daim tawv nqaij, yog li ntawd, cov txheej txheem yog a endothermic txheej txheem. Rau qhov no endothermic txheej txheem muaj ib tug zoo kos npe rau. (c) Thaum tshav kub kub poob los ntawm chav kom tau condensed rau hauv dej, yog li ntawd, cov txheej txheem yog ib qho exothermic tshuaj tiv thaiv.

Kuj paub, yog condensation endothermic los yog exothermic?

Evaporation yog endothermic , txhais tau tias nws yuav siv cua sov tawm ntawm nws ib puag ncig. Condensation txawm li cas los xij, yog qhov opposite nrog nws ua exothermic , qhov twg nws tso cua sov rau hauv ib puag ncig.

Puas yog boiling exothermic?

Vim peb yuav tsum ntxiv cua sov, boiling dej yog txheej txheem uas chemists hu ua endothermic. Kom meej meej, yog tias qee cov txheej txheem xav tau cua sov, lwm tus yuav tsum muab cov cua sov thaum lawv ua. Cov no yog hu ua exothermic . Ib yam li ntawd thaum cov kua dej khov, cua sov tau muab tawm.
