Lub entropy ntawm ib qho system ntawm qhov xoom yog feem ntau yog xoom, thiab txhua qhov xwm txheej tsuas yog txiav txim siab los ntawm cov xov tooj sib txawv hauv av nws muaj. Tshwj xeeb, qhov entropy ntawm cov khoom siv crystalline ntshiab ntawm qhov ntsuas kub tsis zoo yog xoom. … Ntawm xoom xoom tsuas muaj 1 microstate ua tau (Ω=1) thiab ln(1)=0.
Nws txhais li cas thaum entropy yog 0?
Txoj Cai Thib Peb tau hais tias, "Lub entropy ntawm cov siv lead ua zoo tag nrho yog xoom thaum qhov kub ntawm cov siv lead ua sib npaug rau xoom (0 K)." Raws li Purdue University, "Lub siv lead ua yuav tsum zoo tag nrho, los yog lwm yam yuav muaj qee qhov kev tsis sib haum xeeb.
Yuav ua li cas ntawm qhov xoom?
Ntawm xoom kelvin (rho tawm 273 degrees Celsius) cov khoom tsis txav mus thiab txhua yam teeb meem ploj mus. … Ntawm xoom kelvin (rho tawm 273 degrees Celsius) cov khoom tsis txav mus thiab tag nrho cov teeb meem ploj mus. Yog li, tsis muaj dab tsi tuaj yeem txias dua li xoom xoom ntawm Kelvin nplai.
Puas entropy sib npaug zero?
Entropy yog ib qho kev ntsuas ntawm molecular disorder lossis randomness ntawm lub system, thiab txoj cai thib ob hais tias entropy tuaj yeem tsim tau tab sis nws tsis tuaj yeem rhuav tshem. S S S +=∆ Qhov no hu ua entropy tshuav nyiaj li cas. Yog li ntawd, qhov hloov pauv ntawm qhov system yog xoom yog tias lub xeev ntawm qhov system tsis hloov thaum lub sijhawm txheej txheem.
Puas yog entropy txo qis ntawm qhov ntsuas kub tsis txaus?
Tsis muaj xoom yog qhov txwv qis tshaj plaws ntawmntsuas kub ntsuas kub, alub xeev uas lub enthalpy thiab entropy ntawm ib tug cooled zoo tagnrho gas ncav cuag lawv yam tsawg kawg nkaus tus nqi, coj li xoom kelvins. … Hauv quantum-mechanical piav qhia, qhov teeb meem (khoom) ntawm qhov xoom yog nyob rau hauv nws lub xeev hauv av, lub ntsiab lus ntawm lub zog sab hauv qis tshaj.
