Combustion yog cov tshuaj tiv thaiv oxidation uas ua rau cov cua sov, thiab nws yog li ntawd ib txwm exothermicTxhua yam tshuaj lom neeg ua ntej tawg cov ntawv cog lus thiab tom qab ntawd ua cov tshiab los tsim cov ntaub ntawv tshiab. … Yog hais tias lub zog tso tawm los ntawm cov ntawv cog lus tshiab ntau dua li lub zog xav tau los rhuav tshem cov ntawv cog lus qub, cov tshuaj tiv thaiv yog exothermic.
Puas combustion ib txwm exothermic?
Cov tshuaj tiv thaiv combustion yog yuav luag ib txwm exothermic(piv txwv li, lawv muab cov cua sov). Piv txwv li thaum ntoo hlawv, nws yuav tsum ua li ntawd nyob rau hauv lub xub ntiag ntawm O2 thiab ntau tshav kub yog tsim: Ntoo thiab ntau yam khoom uas combust yog organic (piv txwv li, lawv yog ua los ntawm carbon, hydrogen thiab oxygen).
Vim li cas combustion exothermic GCSE?
Thaum muaj tshuaj lom neeg tshwm sim, lub zog xa mus rau lossis los ntawm ib puag ncigThaum lub zog xa mus rau ib puag ncig, qhov no hu ua cov tshuaj tiv thaiv exothermic, thiab qhov kub ntawm qhov chaw ib puag ncig. nce. Piv txwv ntawm exothermic cov tshuaj tiv thaiv muaj xws li: combustion reactions.
Puas combustion exothermic lossis endothermic piav?
Combustion as an Exothermic Reaction Txhua yam kev sib combustion yog exothermic tshua. Thaum lub sij hawm combustion cov tshuaj tiv thaiv, ib yam khoom kub hnyiab raws li nws ua ke nrog oxygen. Thaum cov khoom kub hnyiab, lawv feem ntau muab lub zog ua kom sov thiab lub teeb.
Vim li cas enthalpy hloov ntawm combustion yog ib txwm exothermic?
Yuav muaj yim daim ntawv cog lus hauv cov reactants thiab yim hauv cov khoom, yog li yog tias qhov nruab nrab enthalpy ib daim ntawv cog lus siab dua hauv cov reactants, cov tshuaj tiv thaiv yog exothermic.

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 .
Cov tshuaj tiv thaiv exothermic tshwm sim li cas?
Ib qho tshuaj tiv thaiv exothermic tshwm sim thaum qhov kub ntawm qhov system nce vim qhov hloov pauv ntawm cov cua sovCov cua sov no tau tso rau hauv ib puag ncig, ua rau tag nrho qhov tsis zoo rau cov cua sov ntawm cov tshuaj tiv thaiv (qrxn<
Thaum twg cov tshuaj tiv thaiv exothermic thim rov qab?
Yog tias cov tshuaj tiv thaiv tom ntej yog exothermic qhov rov qab cov tshuaj tiv thaiv yuav yog endothermic, thiab yog tias cov tshuaj tiv thaiv tom ntej yog endothermic qhov rov qab cov tshuaj tiv thaiv yuav exothermic. Cov tshuaj tiv thaiv uas ua rau tsis muaj qhov hloov pauv ntawm qhov kub thiab txias hauv lub thawv insulated tau hais tias yog athermal .
Puas knitting thiab crocheting tib yam yog vim li cas los yog vim li cas tsis?
Knitting thiab crocheting is similar, tseem txawv. Ob qho khoom siv tes ua siv xov paj los ua cov khoom, tab sis knitting yog ua tiav nrog ob rab koob thiab cov stitches yog loops. Crocheting, ntawm qhov tod tes, yog ua tiav nrog ib qho crochet nuv thiab cov stitches zoo li cov pob me me .
Yuav sau li cas vim li cas thiab yog vim li cas?
Kev txhais ntawm yog vim li cas thiab (tus) yog li ntawd: yog vim li cas rau ib yam Nws piav qhia vim li cas thiab yog li ntawd ntawm tus nqi nce . Yuav ua li cas thiab yog vim li cas? Txhua qhov laj thawj thiab qhov laj thawj, ib yam li hauv Nws tau mus rau qhov laj thawj thiab yog li ntawm lub koom haum kev saws me nyuam txoj cai thiab cov txheej txheem.
