Adiabatic vs Isolated Systems
Ib txheej txheem adiabatic yog txheej txheem uas cov cua kub hloov mus rau cov roj ua haujlwm yog xoom. Ib qho kev sib cais yog ib qho system uas raug kaw tag nrho ntawm ib puag ncig. Hauv cov thermodynamics, cov txheej txheem adiabatic thiab cov tshuab cais tawm yog qhov tseem ceeb heev. Kev nkag siab zoo hauv ob lub ntsiab lus no ua ke nrog lwm cov ntsiab lus koom nrog yuav tsum nkag siab cov ntsiab lus hauv ob qho tib si classical thiab statistical thermodynamics. Peb ntsib cov txheej txheem adiabatic thiab cov kab ke sib cais, uas yuav luag zoo tag nrho hauv peb lub neej txhua hnub. Nyob rau hauv tsab xov xwm no, peb yuav tham txog dab tsi cais kab ke thiab cov txheej txheem adiabatic yog, lawv cov ntsiab lus, lwm cov ntsiab lus cuam tshuam nrog ob, qhov zoo sib xws ntawm cov txheej txheem cais thiab cov txheej txheem adiabatic, qee qhov piv txwv rau ob qho no, thiab thaum kawg qhov txawv ntawm cov kab ke cais. thiab cov txheej txheem adiabatic.
Dab tsi yog Isolated System?
Ib qho kev sib cais yog ib qho system uas tsis muaj teeb meem lossis lub zog hloov pauv tau nrog ib puag ncig. Qhov no yog lub tswv yim tseem ceeb heev hauv thermodynamics. Tag nrho cov teeb meem thiab lub zog ntawm ib qho kev sib cais yog khaws cia. Muaj peb lwm lub tshuab hauv thermodynamics. Lub kaw lus kaw yog ib qho system uas hloov hluav taws xob nrog ib puag ncig yog ua tau, tab sis qhov hloov pauv tsis tau. Lub kaw lus qhib yog ib qho system uas ob qho tib si lub zog thiab cov teeb meem tuaj yeem hloov mus nrog ib puag ncig. Lub raj mis thermos yog qhov piv txwv zoo tshaj plaws nyob rau hauv peb lub neej niaj hnub mus rau ib qho kev sib cais. Txawm li cas los xij, ib puag ncig ntawm lub qab ntuj khwb tsis tau txhais, lub ntiaj teb raug suav tias yog ib qho kev sib cais. Yog li ntawd, rau txhua qhov system, ib puag ncig yog sib npaug rau lub kaw lus tshem tawm ntawm lub ntiaj teb. Cia peb xav tias muaj ib qho kev sib cais, uas ua haujlwm nyob ib puag ncig. Txij li thaum tsis muaj kev sib pauv hluav taws xob ua tau ntawm qhov system thiab ib puag ncig, cov txheej txheem yuav tsum yog txheej txheem adiabatic. Nws tuaj yeem pom tias txhua qhov kev sib cais yog adiabatic.
Tus Txheej Txheem Adiabatic yog dab tsi?
Ib txheej txheem adiabatic yog txheej txheem uas tsis muaj cua sov hloov ntawm qhov system thiab ib puag ncig. Cov txheej txheem Adiabatic tuaj yeem tshwm sim hauv ob txoj hauv kev. Thawj txoj kev yog los ntawm kev muaj ib qho kev sib cais uas lub ntim tuaj yeem sib txawv. Txhua yam txheej txheem tshwm sim nyob rau hauv cov xwm txheej zoo li no yog txheej txheem adiabatic. Qhov thib ob txoj kev yog ua haujlwm ntawm lub kaw lus hauv lub sijhawm tsis txaus ntseeg. Txoj kev no tsis muaj cua sov hloov mus rau nruab nrab ntawm qhov system thiab ib puag ncig. Lub compression ntawm lub twj tso kua mis roj siv los sau cov raj yog ib qho piv txwv zoo ntawm cov txheej txheem adiabatic. Kev nthuav dav dawb ntawm cov pa roj kuj tseem yog txheej txheem adiabatic. Cov txheej txheem Adiabatic tseem hu ua cov txheej txheem isocaloric.
Qhov txawv ntawm Adiabatic Process thiab Isolated System yog dab tsi?
• Tsuas yog cov txheej txheem adiabatic tau tso cai rau cov kab ke sib cais, tab sis tsis yog tag nrho cov txheej txheem adiabatic tau ua tiav ntawm cov kab ke cais.
• txheej txheem Adiabatic yog txhais raws li ib theem ntawm cov xeev ntawm lub system, whereas lub cais system yog ib hom ntawm system.
• cov txheej txheem Adiabatic kuj tuaj yeem tshwm sim hauv cov kaw lus kaw.
