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.

Dab tsi yog qhov hloov pauv entropy ntawm tus txheej txheem thim rov qab?

Entropy yog qhov poob ntawm lub zog muaj los ua haujlwm. Lwm daim ntawv ntawm txoj cai thib ob ntawm thermodynamics hais tias tag nrho cov entropy ntawm lub kaw lus yuav nce los yog nyob twj ywm; nws yeej tsis txo qis. Entropy yog xoom hauv cov txheej txheem thim rov qab; nws nce nyob rau hauv ib tug irreversible txheej txheem.

Dab tsi yog entropy hauv adiabatic irreversible txheej txheem?

Qhov hloov pauv entropy nyob ntawm kev sib pauv cua sov ntawm lub adiabatic system. Li no, peb tuaj yeem hais tias qhov kev xaiv raug yog (B), uas yog entropy ntawm adiabatic reversible txheej txheem is xoom.

Vim li cas entropy nce hauv irreversible adiabatic txheej txheem?

Yog li kom tau txais qhov hloov pauv hloov pauv rau cov txheej txheem adiabatic irreversible, koj yuav tsum tsim ib txoj hauv kev rov qab los ntawm tib ob lub xeev kawg, thiab txoj kev thim rov qab no yuav tsis yog adiabatic.. Ntawm txoj kev thim rov qab, koj yuav tsum tau ntxiv cua sov rau lub kaw lus txhawm rau hloov pauv ntawm tib ob lub xeev kawg.

Qhov kev hloov pauv no puas yuav ua rau muaj kev hloov pauv hloov pauv?

Qhov kev hloov pauv no puas yuav ua rau muaj kev hloov pauv hloov pauv?

Yog li, yog tias muaj kev hloov pauv, piv txwv li, kev ntxig lossis tshem tawm ntawm nucleotide, tshwm sim, qhov no tuaj yeem ua rau kev hloov pauv ntawm kev nyeem ntawv. Nws hloov tag nrho cov amino acid ib ntus. Cov kev hloov pauv no yog hu ua frameshift mutation (tseem hu ua kev nyeem ntawv hloov pauv, nyeem ntawv hloov pauv, lossis framing yuam kev).

Puas yog cov txheej txheem polytropic thim rov qab?

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.

Hauv cov txheej txheem thim rov qab polytropic?

Hauv cov txheej txheem thim rov qab polytropic?

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.

Rau cov txheej txheem isochoric hloov pauv hauv lub zog sab hauv yog?

Rau cov txheej txheem isochoric hloov pauv hauv lub zog sab hauv yog?

Thaum tus txheej txheem isochoric, tshav kub nkag (nplooj) lub kaw lus thiab nce (qis) lub zog sab hauv. Thaum lub sij hawm tus txheej txheem isobaric expansion, cua sov nkag mus rau hauv lub system. Ib feem ntawm cov cua sov yog siv los ntawm lub kaw lus ua haujlwm ntawm ib puag ncig;

Rau cov txheej txheem lossis cov txheej txheem?

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.
