Los ntawm txoj cai thib ob ntawm thermodynamics: Txoj cai thib ob ntawm thermodynamics hais tias qhov entropy ntawm ib qho cais qhov system yeej tsis txo qis, vim tias cov tshuab cais ib txwm hloov mus rau qhov sib npaug ntawm qhov ntsuas kub, lub xeev nrog siab kawg entropy.
Yuav ua li cas rau entropy hauv ib qho kev sib cais?
Lub entropy ntawm ib qho kev sib cais ib txwm nce lossis tseem nyob tas li. Qhov ntau lub xeev muaj nyob rau hauv qhov system nrog qhov muaj txiaj ntsig zoo, qhov ntau dua qhov entropy. Hauv paus, tus naj npawb ntawm microstates yog ib qho kev ntsuas ntawm qhov muaj feem cuam tshuam ntawm lub cev.
Puas cais qhov system yog qhov ntsuas kub sib npaug?
Txoj Cai. Rau qhov kev sib cais tag nrho, S yog qhov siab tshaj plaws ntawm qhov ntsuas kub sib npaug. Rau lub kaw lus uas tswj qhov kub thiab ntim tas li, A yog qhov tsawg kawg nkaus ntawm qhov sib npaug ntawm qhov ntsuas kub. Rau lub kaw lus uas tswj qhov kub thiab txias tsis tu ncua, G yog qhov tsawg kawg nkaus ntawm thermodynamic equilibrium.
Dab tsi yog qhov entropy ntawm lub tshuab ntsuas cua sov hauv qhov sib npaug?
Rau qhov ntsuas kub sib npaug nrog lub zog muab, enttropy yog ntau dua li ntawm lwm lub xeev nrog tib lub zog. Rau lub xeev qhov sib npaug ntawm qhov sib npaug nrog lub siab thiab qhov kub thiab txias, Gibbs lub zog dawb yog me dua li ntawm lwm lub xeev nrog tib lub siab thiab kub.
Can ibcais system tsim entropy?
Txoj cai thib ob ntawm thermodynamics hais tias entropy ib txwm loj hlob hauv cov kab ke cais. Daim ntawv ceeb toom tias entropy tsis tas yuav nce hauv qhov qhib qhov system.
