A microstate defines qhov tseem ceeb ntawm txhua qhov ua tau microscopic variables. Hauv cov txheej txheem classical ntawm cov ntsiab lus, piv txwv li, microstate txhais txoj haujlwm thiab lub zog ntawm txhua qhov khoom. Hauv quantum mechanical system, nws txhais tau tias tus nqi ntawm lub wavefunction ntawm txhua qhov chaw hauv qhov chaw.
microstates siv rau dab tsi?
Peb tuaj yeem suav cov lej rau cov macrostate muab thiab peb pom tias microstates muab cov lus teb rau peb txog kev sib raug zoo ntawm molecular motion thiab entropy- piv txwv li, ntawm cov molecules (los yog atoms lossis ions) tas li ua kom nrawm nrawm, sib tsoo nrog ib leeg, txav deb ntawm qhov chaw (lossis, tsuas yog vibrating nrawm hauv …
Dab tsi yog thiab qhov tseem ceeb ntawm microstates?
Microstates txuas ntxiv rau tib neeg rau lawv tsoomfwv thiab niches khawscov microstates tsom mus rau kev nce qib. Ib qho niche ua rau lawv muaj feem cuam tshuam nrog kev sib tw nrog lwm lub xeev thiab ua rau muaj kev nkag siab ntawm kev sib haum xeeb.
Yuav ua li cas microstates cuam tshuam rau entropy?
Qhov tshwm sim uas lub kaw lus yuav tshwm sim nrog nws cov khoom hauv ib qho kev faib khoom yog proportional rau tus naj npawb ntawm microstates hauv kev faib khoom. Txij li thaum entropy nce logarithmically nrog rau tus lej ntawm microstates, qhov feem ntau yuav tshwm sim yog li ntawd yog ib qho ntawm qhov loj tshaj entropy.
Qhov txawv ntawm microstate thiab microstate yog dab tsi?
Nyob rau hauv physics, microstate yog txhais raws li kev npaj ntawm txhua molecule nyob rau hauv lub system ntawm ib qho instant. Lub macrostate yog txhais los ntawm macroscopic zog ntawm lub cev, xws li kub, siab, ntim, thiab lwm yam. Rau txhua lub macrostate, muaj ntau microstates uas ua rau tib lub macrostate.
