Lo lus "polytropic" yog thawj zaug los piav qhia txhua txoj kev thim rov qab ntawm txhua qhov qhib lossis kaw ntawm cov pa roj lossis vapor uas cuam tshuam txog kev hloov pauv thiab ua haujlwm, xws li cov lus teev tseg kev sib xyaw ntawm cov khoom tau khaws cia tas mus li thoob plaws hauv cov txheej txheem.
Puas yog tag nrho cov txheej txheem polytropic thim rov qab?
Polytropic txheej txheem yog sab hauv thim rov qab. Qee qhov piv txwv yog vapors thiab cov pa roj zoo tag nrho hauv ntau cov txheej txheem tsis ntws, xws li: n=0, ua rau P=tas li xws li txheej txheem isobaric.
Koj ua li cas xam cov txheej txheem polytropic?
Cov Txheej Txheem Polytropic tuaj yeem txhais tau tias yog cov txheej txheem uas cov cua sov nqus los ntawm cov pa vim qhov ntsuas kub ntawm chav nyob tas li. Cov txheej txheem polytropic yog txheej txheem thermodynamic uas tuaj yeem qhia tau siv cov kab zauv hauv qab no. PV =C, Nws yog kev sib npaug ntawm cov txheej txheem Polytropic.
Puas yog txheej txheem isentropic ib txwm thim rov qab?
A reversible, adiabatic txheej txheem yog ib txwm isentropic txij thaum tsis muaj entropy tiam vim irreversibilities (sgen=0) thiab tsis muaj kev hloov ntawm entropy vim tshav kub hloov (ds=? … Q /T=0).

Puas yog cov txheej txheem polytropic thim rov qab?
cov txheej txheem Polytropic yog internally reversible . Qee qhov piv txwv yog vapors thiab cov pa roj zoo meej gases Muaj peb chav kawm ntawm cov roj zoo tagnrho: classical lossis Maxwell-Boltzmann cov roj zoo tagnrho, qhov zoo tshaj plaws quantum Bose gas, muaj li ntawm bosons, thiab.
Dab tsi yog txheej txheej txheej txheem nyob rau hauv lub ntiaj teb?
Lub neej muaj txheej txheem ntawm lub ntiaj teb yog the Biosphere. Lub neej muaj dabtsi? Cov kabmob lub neej yog qhov tseem ceeb ntawm lub sijhawm ntev ntawm cov kabmob tuaj yeem xav tau ua raws li qhov xav tau hauv kev ua haujlwm ua ntej tau teev tseg.
Cov txheej txheem thim rov qab puas ua tau?
Vim tias nws yuav siv sijhawm tsis kawg rau cov txheej txheem thim rov qab kom tiav, cov txheej txheem thim rov qab zoo kawg yog ua tsis tau. Txawm li cas los xij, yog tias qhov kev hloov pauv tau teb sai dua li qhov hloov pauv, qhov kev sib txawv ntawm kev thim rov qab tuaj yeem ua tsis tiav.
Rau cov txheej txheem thim rov qab adiabatic hloov pauv hauv entropy yog?
peb pom tias qhov hloov pauv hloov pauv ntawm qhov system thaum lub sijhawm hloov pauv, cov txheej txheem adiabatic yog zero. Dab tsi yog qhov hloov pauv entropy ntawm tus txheej txheem adiabatic? Yog li ntawd, kev hloov pauv hauv entropy rau cov txheej txheem adiabatic sib npaug rau xoom.
Rau cov txheej txheem lossis cov txheej txheem?
Cov txheej txheem yog feem ntau yog ntau lub npe hais txog cov qauv uas tuaj yeem txiav txim siab. Nws cov lus yog cov qauv, tab sis cov pov thawj qhia tau tias cov txheej txheem feem ntau raug siv los ua cov lus thiab ntau ntau, zoo li cov ntaub ntawv thiab cov txheej txheem thiab lawv cov lus siv tsawg dua cov ntaub ntawv thiab cov txheej txheem.
