Melting yog ib endothermic cov tshuaj tiv thaiv nyob rau hauv uas tag nrho cov nqi ntawm tshav kub nyob rau hauv cov khoom, kuj hu ua enthalpy, nce.

Ib yam li ntawd, nws raug nug, yog Melting endothermic?

Melting tsuas yog qhov ntawd. Thaum ib yam dab tsi yog 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.

Yog vim li cas yog lub melting ntawm dej khov endothermic? Raws li tau piav saum toj no, dej khov yaj yog ib endothermic tshuaj tiv thaiv vim nws yuav tsum tau cua sov rau cov tshuaj tiv thaiv tshwm sim. Yog li ntawd, ib puag ncig, nyob rau hauv Dr. Lavelle tus piv txwv, ib tug txhais tes, yuav txias vim hais tias lub tshav kub yuav tsum tau rau cov tshuaj tiv thaiv yog absorbed los ntawm ib puag ncig (kev txuag lub zog).

Tom qab, lo lus nug yog, yog exothermic melting?

Vim peb yuav tsum tau ntxiv cua sov, boiling dej yog ib tug 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 . Cov kev hloov ntawm lub xeev yuav tsum muaj ib tug ruaj khov yaj , kua dej khov, kua boiling los yog roj condensing.

Puas yog ib qho khoom rau cov kua endothermic lossis exothermic?

Kev hloov ntawm lub xeev txiav txim ntau dua mus rau lub xeev txiav txim tsawg dua (xws li a ua kua gas) yog endothermic . Kev hloov pauv ntawm lub xeev qis dua mus rau lub xeev xaj ntau dua (xws li a ua kua rau a khov kho ) ib txwm exothermic . Kev hloov pauv ntawm a khoom ua kua hu ua fusion (los yog melting).

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
