Thaum muaj cov tshuaj tiv thaiv endothermic, reactants nyob rau theem qis zog piv rau cov khoom-raws li qhia hauv daim duab qhia lub zog hauv qab no. Hauv lwm lo lus, cov khoom lag luam tsis ruaj khov dua li cov reactants. … Zuag qhia tag nrho Δ H ΔH ΔH rau cov tshuaj tiv thaiv yog qhov tsis zoo, piv txwv li, lub zog raug tso tawm rau hauv daim ntawv ntawm tshav kub.
Yuav ua li cas rau cov reactants thiab cov khoom nyob rau hauv cov tshuaj tiv thaiv endothermic?
Txhua yam tshuaj tiv thaiv muaj zog. Lub zog yog siv los rhuav tshem cov ntawv cog lus hauv cov reactants, thiab lub zog raug tso tawm thaum cov ntawv cog lus tshiab tsim hauv cov khoom. Cov tshuaj tiv thaiv kab mob endothermic nqus lub zog, thiab cov tshuaj tiv thaiv exothermic tso tawm lub zog.
Puas yog lub zog reactant hauv cov tshuaj tiv thaiv endothermic?
Cov tshuaj tiv thaiv hluav taws xob thiab cov tshuaj tiv thaiv kab mob endothermic tuaj yeem xav tias muaj lub zog ua ib yam khoom ntawm cov tshuaj tiv thaiv lossis cov tshuaj reactant. Cov tshuaj tiv thaiv exothermic muab tawm lub zog, yog li lub zog yog cov khoom. Cov tshuaj tiv thaiv kab mob endothermic xav tau lub zog, yog li zog yog ib qho reactant.
Dab tsi yog cov reactants nyob rau hauv cov tshuaj tiv thaiv exothermic?
Lo lus exothermic txhais tau tias "tso cua sov." Zog, feem ntau nyob rau hauv daim ntawv ntawm tshav kub, yog tso tawm raws li ib tug exothermic cov tshuaj tiv thaiv pib. Qhov no tau piav qhia hauv daim duab hauv qab no. Cov kab zauv dav dav rau cov tshuaj tiv thaiv exothermic yog: Reactants → Khoom + Zog.
Vim li cas cov reactants ruaj khov dua hauv cov tshuaj tiv thaiv endothermic?
Vim tias lub zog ntawm lub kaw lus txo qis thaum lub sij hawm exothermic cov tshuaj tiv thaiv, cov khoom ntawm lub cev yog qhov ruaj khov dua li cov reactants. … Nyob rau hauv cov tshuaj tiv thaiv endothermic, lub zog yog absorbed thaum lub sij hawm cov tshuaj tiv thaiv, thiab cov khoom yog li muaj ib tug loj npaum li cas ntawm lub zog tshaj cov reactants.

Dab tsi yog qhov txawv ntawm cov tshuaj tiv thaiv thiab tshuaj tiv thaiv?
Raws li nouns qhov txawv ntawm antitype thiab hom yog hais tias antitype yog ib yam dab tsi uas yog cim los yog sawv cev los ntawm ib homthaum hom yog ib pab pawg raws li cov yam ntxwv sib koom; ib hoob . Antitype txhais li cas? 1a:
Dab tsi yog qhov txawv ntawm exothermic thiab endothermic cov tshuaj tiv thaiv?
tshuaj tiv thaiv uas tso lub zogyog hu ua exothermic. Hauv cov tshuaj tiv thaiv exothermic, ntau lub zog raug tso tawm thaum cov ntawv cog lus tsim nyob rau hauv cov khoom dua li siv los rhuav tshem cov ntawv cog lus hauv cov reactants. Cov tshuaj tiv thaiv uas nqus (lossis siv) lub zog hu ua endothermic .
Puas yog cov tshuaj tiv thaiv kab mob tiv thaiv kab mob ua rau lupus?
Antinuclear cov tshuaj tiv thaiv yog autoantibodies - cov tshuaj tiv thaiv kab mob uas tsom rau cov proteins ib txwm nyob hauv lub hauv paus ntawm lub cell. Qhov no dhau los ua qhov tseem ceeb hauv kev kho mob thaum ANAs teeb liab lub cevpib tsom nws tus kheej, uas tuaj yeem ua rau cov kab mob autoimmune, suav nrog lupus, Sjogren's syndrome, thiab cov kab mob sib xyaw ua ke .
Cov neeg mob tiv thaiv kab mob yuav tsum tau txais cov tshuaj tiv thaiv?
Vim li cas CDC thiaj pom zoo tias cov neeg uas muaj kev tiv thaiv kab mob tiv thaiv kab mob tau txais koob tshuaj mRNA COVID-19 ntxiv los ntxiv rau 2-dose thawj koob tshuaj tiv thaiv kab mob mRNA COVID-19? Cov neeg uas muaj kev tiv thaiv kab mob los yog cov neeg siv tshuaj tiv thaiv kab mob yog nyob ntawm muaj kev pheej hmoo ntau rau tus kab mob COVID-19 hnyav .
Vim li cas lub pob txias txias ua rau cov tshuaj tiv thaiv kab mob endothermic?
Cov pob txias txias yog qhov kawg vim lawv nqus cua sov los ntawm lawv ib puag ncig . Cov pob khoom txias ua haujlwm li cas cov tshuaj tiv thaiv kab mob endothermic? Cov kua hauv lub pob txias yog dej. Hauv dej yog lwm lub hnab yas lossis lub raj uas muaj ammonium-nitrate chiv.
