Kub Hloov vs Thermodynamics
Kev hloov pauv cua sov yog ib lub ntsiab lus tham hauv thermodynamics. Cov ntsiab lus ntawm thermodynamics tseem ceeb heev hauv kev kawm ntawm physics thiab mechanics tag nrho. Thermodynamics yog suav hais tias yog ib qho tseem ceeb tshaj plaws ntawm kev kawm hauv physics. Nws yog ib qho tseem ceeb kom muaj kev nkag siab zoo hauv cov ntsiab lus ntawm kev hloov hluav taws xob thiab cov thermodynamics kom ua tau zoo hauv cov teb uas muaj kev siv cov ntsiab lus no. Nyob rau hauv tsab xov xwm no, peb yuav tham txog dab tsi hloov tshav kub thiab thermodynamics yog, lawv cov ntsiab lus thiab kev siv, qhov zoo sib xws ntawm thermodynamics thiab tshav kub hloov thiab thaum kawg qhov sib txawv ntawm thermodynamics thiab tshav kub hloov.
Thermodynamics
Thermodynamics tuaj yeem muab faib ua ob lub ntsiab lus. Qhov thib ib yog cov thermodynamics classical, thiab qhov thib ob yog qhov ntsuas thermodynamics. Classical thermodynamics yog suav tias yog "ua tiav" kev kawm, uas txhais tau hais tias kev kawm ntawm classical thermodynamics tiav. Txawm li cas los xij, kev ntsuas ntsuas ntsuas kub tseem yog qhov chaw tsim kho nrog ntau lub qhov rooj qhib.
Classical thermodynamics yog raws li plaub txoj cai ntawm thermodynamics. Txoj cai zeroth ntawm thermodynamics piav qhia txog qhov sib npaug ntawm thermal, thawj txoj cai ntawm thermodynamics yog raws li kev txuag hluav taws xob, txoj cai thib ob ntawm thermodynamics yog raws li lub tswv yim ntawm entropy thiab txoj cai thib peb ntawm thermodynamics yog raws li Gibbs dawb zog. Statistical thermodynamics feem ntau yog raws li qib quantum, thiab qib microscopic suab thiab mechanics raug txiav txim siab nrog thermodynamics thiab feem ntau cuam tshuam nrog kev txheeb cais.
Hmoov Hloov
Thaum ob yam khoom, uas muaj thermal zog, raug, lawv nyiam hloov lub zog nyob rau hauv daim ntawv ntawm tshav kub. Yuav kom nkag siab txog lub tswv yim ntawm kev hloov hluav taws xob ib qho yuav tsum xub nkag siab lub tswv yim ntawm cov cua sov. Thermal zog tseem hu ua cua sov yog ib daim ntawv ntawm lub zog sab hauv ntawm lub system. Thermal zog yog qhov ua rau qhov kub ntawm qhov system. Lub zog thermal tshwm sim vim qhov kev txav txav ntawm cov molecules ntawm lub cev. Txhua qhov system uas muaj qhov kub siab tshaj qhov xoom muaj qhov zoo thermal zog. Cov atoms lawv tus kheej tsis muaj thermal zog. Cov atoms muaj kinetic zog. Thaum cov atoms sib tsoo nrog ib leeg thiab nrog cov phab ntsa ntawm cov kab ke lawv tso cov thermal zog li photons. Cov cua kub zoo li no yuav ua rau kom lub zog thermal ntawm qhov system. Lub thermal zog ntawm lub system siab dua yuav yog qhov randomness ntawm lub system.
Kub hloov pauv yog qhov txav ntawm cov cua sov ntawm ib qho mus rau lwm qhov. Thaum ob lub tshuab, uas yog thermally tiv tauj, nyob rau hauv qhov sib txawv kub, cua sov los ntawm cov khoom ntawm qhov kub siab dua yuav ntws mus rau cov khoom nrog qhov kub thiab txias kom txog thaum qhov kub sib npaug. Qhov kub gradient yog qhov tsim nyog rau kev hloov pauv hloov pauv hloov pauv.
Tus nqi ntawm cov cua sov hloov pauv yog ntsuas hauv watt, qhov ntsuas kub yog ntsuas hauv joule. Chav tsev watt txhais tau tias yog joules ib lub sijhawm.
Qhov txawv ntawm Kev Hloov Kub Kub thiab Thermodynamics yog dab tsi?
• Thermodynamics yog ib qho kev kawm loj heev uas thaum tshav kub hloov pauv tsuas yog ib qho tshwm sim xwb.
• Thaum tshav kub kub hloov pauv yog qhov tshwm sim kawm nyob rau hauv thermodynamics.
• Thaum tshav kub kub hloov pauv yog lub tswv yim ntsuas ntau tab sis qhov ntsuas kub tsis yog qhov kev kawm.
