Qhov hloov pauv hauv lub zog sab hauv yog xoom txij li lub kaw lus rov qab mus rau tib lub xeev thermodynamic lub xeev thermodynamic Hauv thermodynamics, qhov ntsuas kub ntawm lub cev yog nws cov xwm txheej ntawm lub sijhawm tshwj xeeb; uas yog, tag nrho txheeb xyuas los ntawm qhov tseem ceeb ntawm cov txheej txheem tsim nyog hu ua lub xeev hloov pauv, lub xeev tsis muaj lossis qhov hloov pauv thermodynamic. … Feem ntau, los ntawm lub neej ntawd, lub xeev thermodynamic raug coj los ua ib qho ntawm qhov sib npaug ntawm qhov ntsuas kub. https://en.wikipedia.org › wiki › Thermodynamic_state
Thermodynamic xeev - Wikipedia
(lub ntsiab lus ntawm cov txheej txheem cyclic) thiab lub zog sab hauv yog cov cuab yeej thiab yog li tsuas yog kev ua haujlwm ntawm lub xeev ntawm lub cev. Yog li rau cov txheej txheem cyclic, Q=W.
Puas Q 0 rau cov txheej txheem cyclic?
Kev daws teeb meem. Kev hloov pauv ntawm lub zog hauv cov txheej txheem cyclic yog xoom, txij li lub xeev thawj zaug thiab zaum kawg yog tib yam. Cov hauj lwm ua tiav thiab qhov kom muaj nuj nqis ntawm cov cua sov tau txais hauv cov txheej txheem yog li ntawd tib yam nrog cov cim qhia (R=–Q).
Puas Q W hauv cov txheej txheem cyclic?
Vim cov txheej txheem is cyclic , tsis muaj kev hloov pauv ntawm lub zog sab hauv tom qab txhua lub voj voog. Yog li ntawd, net ua hauj lwm ua nyob rau hauv txhua lub voj voog sib npaug ntawm cov cua sov ntxiv rau lub system. … Lub zog sab hauv tsis hloov pauv, yog li cov cua sov tshem tawm yog Q3=W3.
Delta Q yog dab tsi hauv cov txheej txheem cyclic?
Nyob rau hauv cov txheej txheem cyclic pom hauv daim duab ΔU1 thiab ΔU2 sawv cev rau kev hloov pauv hauv lub zog sab hauv hauv cov txheej txheem A thiab B feem. Yog tias △Q yog cov cua sov uas muab rau lub kaw lus hauv cov txheej txheem thiab ΔW yog cov haujlwm ua haujlwm tau ua los ntawm qhov system hauv txheej txheem, ces (A) ΔU1 + ΔU2=0 (C) ΔQ−ΔW=0 (B) ΔU1− ΔU2=0 (D) ΔQ+ΔW=0
Cov txheej txheem cyclic yog dab tsi?
Thaum ib lub kaw lus tau dhau los ua cov txheej txheem cyclic, nws qhov pib thiab qhov kawg ntawm lub zog sib npaug. Yog li ntawd, kev hloov pauv ntawm lub zog sab hauv hauv ib qho txheej txheem cyclic yog xoom. Siv thawj txoj cai ntawm thermodynamics rau cov txheej txheem cyclic, peb tau txais. ΔE=Q+W.

Vim li cas cov ntawv xov xwm pabcuam raug muab tso rau hauv cov txheej txheem tshuaj xyuas?
Lawv ceeb toom rau cov tswv dav hlau thiab cov tswv ntawm cov xwm txheej tsis zoo uas xav tau kev tshuaj xyuas tshwj xeeb, hloov pauv, lossis kho dua. Daim Ntawv Qhia Kev Pabcuam (S.B.) yog ib daim ntawv ceeb toom rau tus neeg tsav dav hlau los ntawm lub chaw tsim khoom qhia nws txog kev txhim kho cov khoom .
Dab tsi yog cov xwm txheej rau txheej txheem haber?
Cua yog 78 feem pua nitrogen thiab yuav luag tag nrho cov seem yog oxygen. Thaum hydrogen hlawv hauv huab cua, cov pa oxygen ua ke nrog hydrogen - tawm hauv nitrogen tom qab. a qhov kub siab - txog 450 ° C a siab siab - txog 200 cua(200 npaug li qub siab) Vim li cas cov xwm txheej siv hauv Haber txheej txheem?
Cov txheej txheem twg yog txheej txheem gradational?
Gradational processes Weathering=breakdown of material in place Gradation=leveling of land degradation (erosion)=tshem tawm highs transport=txav ntawm cov khoom aggradation (deposition)=filling in lows Tectonic txheej txheem tsim los ntawm roughen lub ntiaj teb Gradational rog theem tawm highs thiab sau nyob rau hauv lows … Qhov twg ntawm cov txheej txheem hauv qab no yog cov txheej txheem gradational?
Puas yog txheej txheej txheej txheem siv los siv?
Kev txhim kho lub koom haum (OD) yog txheej txheej txheej txheem rau kev siv cov kev npaj hloov pauv kom ua rau tib neeg thiab cov koom haum ua tau zoo . Puas yog ib qho kev coj cwj pwm teb rau qhov tiag? Kev coj cwj pwm ntawm qhov kev xav ntawm kev xav yog qhov qhia tau tseeb ntawm kev xav.
Dab tsi ntawm cov hauv qab no tsis muaj tseeb rau cov txheej txheem cyclic?
Kev piav qhia. W=0 tsis muaj tseeb rau cov txheej txheem cyclic. Yog li ntawd, kev ua hauj lwm ua los ntawm lub system nyob rau hauv ib tug cyclic transformation yog sib npaug zos rau lub tshav kub absorbed los ntawm lub system. Ib qho piv txwv ntawm cov kab ke no yog lub tub yees lossis cua txias .
