Lub thermodynamic equilibrium ntawm cov lom system

Thermodynamics yog hu ua tus ceg ntawm physics uas kawm cov thermal zog thiab cov ntsiab cai ntawm nws cov kev faib thoob plaws hauv lub ntim ntawm ib yam khoom los yog ib tug kev ib puag ncig. Qhov no kev qhuab qhia yog los ntawm tej qho universal hauv paus ntsiab lus thiab siv cov ntaub ntawv uas muaj ntau lwm yam sciences. Lub thermodynamic equilibrium yog lub pobzeb ntawm no kheej ntawm scientific kev txawj ntse.

Ib tug ntawm cov tseem ceeb tshaj plaws thiab tej zaum cov feem ntau cov kev khoom teejtug uas yog muaj sia nyob yog lawv nws muaj peev xwm zog cia thiab nws cov conversion rau hauv ib tug ntau yam ntawm cov ntaub ntawv. Thermodynamic equilibrium - nws yog ib lub xeev ntawm lub system thaum nws tsis thiab cov yam ntxwv yuav hloov tsis tau lub sij hawm tsis muaj tus ntawm tej lwm yam.

Uas yog: raws cais lub cev system muaj ib los yog ntau tshaj lub cev khoom, yuav nyob twj ywm indefinitely nyob rau hauv ib lub xeev ntawm tshuav nyiaj li cas. Yog hais tias koj ua txhaum lub thermodynamic equilibrium, tej system yuav yuav rov qab mus rau lawv ruaj khov lub xeev nyob rau hauv lawv tus kheej. Qhov no yog ib tug ntawm hauv paus ntsiab cai ntawm physics, nyob rau hauv uas ntau heev yuav ua tau nyob rau hauv peb lub neej thiab nyob rau hauv cov xwm.

Nws yog ib qho yooj yim mus xav txog tej yam lub thermodynamic equilibrium yog ib qho piv txwv ntawm xws li ib tug natural tib neeg cwj pwm ntawd, raws li ib tug thermos ntawm kub tshuaj yej, uas yog lub feem ntau raug rho tawm system. Ntawm cov hoob kawm, tus kub nyob rau hauv tej taw tes ntawm cov tshuaj yeeb dej caw (nyob rau hauv cov ntaub ntawv no - tshuaj yej) yuav tsum yog tib yam. Tiam sis yog tias dipped nyob rau hauv ib tug thermos voos xwmfab dej khov, cov thermodynamic equilibrium yog ib pliag ntxhov, raws li tshwm sim kub sib txawv nyob rau hauv ntau thaj tsam ntawm cov kua.

Thaum no thaum tshav kub kub hloov lwm lub tsev yuav coj qhov chaw ntawm lub cheeb tsam ntawm dua kub ntawm lub colder feem, kom txog rau thaum tag nrho ntim yog tsim los homogeneity thermal hom. Thaum zoo li no tshwm sim, stability yuav tsum tau rov qab. Qhov no yog yuav ua li cas tej thermodynamic system, hais txog ntawm qhov luaj li cas thiab tus naj npawb ntawm cov khoom, uas nws yog tsim los.

Lub ntsiab mob ntawm equilibrium, uas yog tib yam kub qhia rau tag nrho cov ntsiab lus ntawm lub cev, tshwj xeeb tshaj yog ib qho tseem ceeb rau muaj sia nyob. Tag nrho lom khoom ntawm kev zog kom tsawg yuav tsum tau kom muaj ib lub neej zoo. Tag nrho lom dab kuj xav tau ib tug ruaj khov thaum tshav kub kub hloov lwm lub tsev thiab teeb tis.

Piv txwv li, cov nroj tsuag accumulating hnub ci zog, hloov nws mus rau ib tug tshuaj daim ntawv cog lus ntawm cov organic tshuaj los ntawm photosynthesis. Nyob rau hauv tus tsiaj kab mob txhua yam yog raws nraim cov lus rov - organic tshuaj muab los ntawm cov zaub mov, yog hloov dua siab tshiab mus ua lub zog. Txhua yam dab (tus neeg sawv cev ntawm ob qho tib si nroj tsuag thiab tsiaj lub neej) tshwm sim nyob rau hauv nruj raws li cov ntsiab cai ntawm txoj thermodynamic system.

Basic ntsiab ntawm thermodynamics yog universal thiab inviolable rau nyob lom systems, thiab rau tswg xwm. thermodynamics hauv paus ntsiab lus qhia tias tej sau los ntawm lwm yam kev yam khoom yuav muab hu ua ib thermodynamic system. Qhov txawv tsuas yog nyob rau hauv qhov loj thiab xov tooj ntawm cov khoom. Piv txwv li systems yuav pab raws li lub hlwb ntawm peb lub cev, lub plawv thiab lwm yam hauv nruab nrog cev. Tag nrho lub cev yog tseem nyob rau hauv ib lub siab, yog ib tug thermodynamic system. Txawm xws giant qhov chaw raws li biosphere, dej hiav txwv kuj zwm rau pawg no. Thiab lawv yog cov yuav raug mus rau tib cov kev cai ntawm thermodynamic equilibrium.
