Qhov kev tsis sib haum sab nraud tshwm sim vim kub qhov sib txawv ntawm qhov chaw thiab cov dej ua haujlwm ntawm cov khoom siv hluav taws xobthiab qhov kub ntawm qhov sib txawv ntawm lub dab dej thiab cov dej ua haujlwm ntawm qhov kub tsis kam. Yog hais tias qhov hypothetical tshav kub qhov chaw thiab dab ntxuav tes yog txiav txim siab ces tus txheej txheem yuav reversible.

Yuav ua li cas hauv qab no yog qhov tsim nyog rau lub voj voog thermodynamic kom hloov tsis tau?

Yuav muaj yuav tsum tsis muaj kev sib txhuam tag nrho. Yuav tsum tsis txhob muaj qhov poob ntawm lub zog vim yog conduction, convection lossis hluav taws xob thaum lub sijhawm ua haujlwm. Yog li, lo lus teb raug yog “Option D”.

Dab tsi yog cov txheej txheem thermodynamic irreversible?

Ib txheej txheem tsis hloov pauv yog thermodynamic txheej txheem uas tawm ntawm qhov sib npaugHais txog lub siab thiab ntim, nws tshwm sim thaum lub siab (lossis ntim) ntawm lub kaw lus hloov pauv sai heev thiab tam sim ntawd. uas lub ntim (los yog lub siab) tsis muaj sij hawm mus cuag equilibrium.

Puas yog lub voj voog thermodynamic thim rov qab?

Txhua qhov taw qhia hauv lub voj voog, lub kaw lus yog nyob rau hauv qhov sib npaug ntawm qhov ntsuas kub, yog li lub voj voog yog thim rov qab(nws qhov hloov pauv hloov pauv yog xoom, vim tias entropy yog lub xeev muaj nuj nqi). … Txoj kev rov ua dua tshiab ntawm txoj hauv kev tso cai rau kev ua haujlwm tas mus li, ua rau lub voj voog yog lub tswv yim tseem ceeb hauv thermodynamics.

Yuav ua li cas yog qhov tsim nyog rau cov txheej txheem thim rov qab?

1.3.

Cov txheej txheem thim rov qab yog qhov sib txawv ntawm qhov sib npaug uas tsis muaj (tseem ceeb) sab hauv kub, siab, thiab nrawm hloov. Cov txheej txheem thim rov qab tuaj yeem thim rov qab ntawm txhua qhov chaw los ntawm cov xwm txheej sab nraud.
