Cov Thib ob txoj cai ntawm Thermodynamics hais tias lub xeev ntawm entropy ntawm tag nrho lub qab ntuj khwb, raws li ib tug cais system, yuav ib txwm nce nyob rau hauv lub sij hawm. Cov ob txoj cai kuj hais tias cov kev hloov nyob rau hauv lub entropy nyob hauv lub qab ntuj khwb yeej tsis muaj qhov tsis zoo.

Dhau li ntawm no, 2nd txoj cai ntawm thermodynamics xeev yog dab tsi?

Thawj Txoj cai ntawm Thermodynamics hais lub zog tsis tuaj yeem tsim lossis rhuav tshem; tag nrho cov zog ntawm lub ntiaj teb nyob twj ywm tib yam. Cov Second Law of Thermodynamics yog hais txog qhov zoo ntawm lub zog. Nws xeev hais tias raws li lub zog yog pauv los yog hloov, ntau thiab ntau ntawm itis wasted.

Kuj Paub, vim li cas 2nd Txoj Cai ntawm Thermodynamics tseem ceeb? Thib ob txoj cai ntawm thermodynamics yog heev tseem ceeb vim hais tias nws tham txog entropy thiab raws li peb tau tham txog, 'entropy dictates seb puas los yog tsis yog ib tug txheej txheem los yog ib tug reactivation yuav spontaneous'.

Ib yam li ntawd, Txoj Cai 2nd ntawm Thermodynamics yog dab tsi thiab muab piv txwv?

Txoj cai thib ob hais tias muaj qhov muaj txiaj ntsig zoo sib txawv hu ua entropy S. Qhov hloov pauv hauv entropy delta S sib npaug rau qhov kub hloov pauv delta Q faib los ntawm qhov kub thiab txias T. piv txwv ntawm cov txheej txheem thim rov qab yog qhov zoo tshaj plaws yuam kev ntws los ntawm cov yeeb nkab constricted. Qhov zoo tshaj plaws txhais tau tias tsis muaj ciam teb layerlosses.

Yuav ua li cas nce lub entropy ntawm ib qho system?

cuam tshuam Entropy Ob peb yam cuam tshuam rau tus nqi ntawm entropy ib qhov system . Yog koj nce kub, ti nce entropy . (1) Ntau zog muab tso rau hauv ib qhov system excites lub molecules thiab tus nqi ntawm random kev ua ub no. (2) Raws li agas nthuav dav hauv a qhov system , entropyincreases.
