Ib isolated system ua tsis pauv zog lossis teeb meem nrog nws ib puag ncig. Piv txwv li, yog cov kua zaub yog nchuav rau hauv ib lub thawv insulated (raws li pom hauv qab no) thiab kaw, tsis muaj qhov sib pauv ntawm cov cua sov lossis teeb meem. Qhov tseeb, muaj ob peb, yog tias muaj, tshuab uas muaj nyob rau hauv lub ntiaj teb no uas yog kiag li cais systems.

Hauv qhov no, dab tsi cais qhov system?

Nyob rau hauv lub cev science, ib cais qhov system yog ob qho ntawm cov hauv qab no: lub cev qhov system kom deb li deb tshem tawm ntawm lwm yam tshuab tias nws tsis cuam tshuam nrog lawv. ib tug thermodynamic qhov system thaiv los ntawm cov phab ntsa tsis txav mus los uas tsis muaj qhov loj lossis lub zog tuaj yeem dhau mus.

Qhov thib ob, tib neeg puas yog ib qho kev kaw kaw lossis qhib qhov system? Qhib systems pauv cov teeb meem thiab lub zog nrog rau sab nraud qhov system . kaw kaw kaws tsuas yog pauv lub zog nrog rau sab nraud qhov system , tsis muaj teeb meem. Ib cais qhov system tsis pauv zog lossis teeb meem nrog rau sab nraud qhov system.

Ua li no, ib qho kev sib cais puas tuaj yeem ua haujlwm tau?

Ib cais qhov system yog a qhov system nyob rau hauv uas tsis muaj kev hloov ntawm lub zog ntawm lub qhov system thiab ib puag ncig. Yog li, tag nrho ua haujlwm hloov mus rau ib qho cais qhov system yog zero. Yog li tsis muaj qhov tsis zoo lossis qhov zoo ua haujlwm.

Vim li cas thiaj tsis muaj kev sib cais?

Ib cais qhov system tsis pauv zog lossis teeb meem nrog nws ib puag ncig. Piv txwv li, yog cov kua zaub yog nchuav rau hauv ib lub thawv insulated thiab kaw, nyob ntawd yog tsis muaj pauv cov cua sov los yog teeb meem. Yog li, xyaum nws yog tsis yooj yim sua kom ua 100% cais qhov system.

Dab tsi yog lub tswv yim ntawm kev txhawb nqa ntawm kev sib cais ntawm kev sib deev?

Kev txhawb zog yog cov txheej txheem los ntawm kev xaiv ntuj tsim kom muaj kev sib cais ntawm kev sib deev. Kev txhawb zog tuaj yeem tshwm sim raws li hauv qab no: Thaum ob pawg neeg uas tau khaws cia sib nrug, rov qab los rau hauv kev sib cuag, qhov kev sib cais ntawm cov menyuam yaus yuav ua tiav lossis tsis tiav. Yog tias nws ua tiav, speciation tau tshwm sim

Puas muaj ntau tshaj ib qho kev sib tshuam ntawm cov duab ntawm ob kab sib npaug?

Tshwj tsis yog cov duab ntawm ob kab sib npaug sib npaug sib npaug, tsuas muaj ib qho kev sib tshuam xwb, vim tias ob kab tuaj yeem sib tshuam hauv feem ntau ntawm ib qho. Los ntawm qhov ntawd, txav ib chav mus rau sab xis thiab txav mus rau vertically tus nqi ntawm txoj kab nqes mus rau qhov chaw thib ob. Tom qab ntawd txuas ob lub ntsiab lus

Thaum ib qho kev sib cais ua rau muaj kev hloov pauv hloov pauv ntawm lub ntiaj teb nce ntxiv?

Txij li thaum lub kaw lus raug cais tawm, tsis muaj cua sov tuaj yeem khiav tawm (tus txheej txheem yog li adiabatic), yog li thaum lub zog ntws tawm hauv lub cev, qhov entropy ntawm qhov system nce, piv txwv li Δ Ssys> 0. Yog li ntawd, lub entropy ntawm lub system yuav tsum tau nce rau ib tug spontaneous txheej txheem nyob rau hauv no cais system

Puas yog nws ua tau rau ib qho kev sib npaug ntawm ob txoj kab sib npaug kom tsis muaj kev daws teeb meem piav qhia koj qhov laj thawj?

Cov kab ke ntawm kab sib npaug tuaj yeem tsuas muaj 0, 1, lossis ib qho kev daws teeb meem tsis kawg. Ob kab no tsis tuaj yeem hla ob zaug. Cov lus teb raug yog tias qhov system muaj ib qho kev daws teeb meem.
