Qhov sib txawv tseem ceeb ntawm qhov tseeb thiab pseudo cov khoom tseem ceeb yog qhov tseeb cov khoom tseem ceeb yog cov khoom tseem ceeb ntawm lub kaw lus, uas tau txiav txim siab thermodynamically, qhov pseudo tseem ceeb cov khoom yog qhov pom tseeb ntawm txhua qhov ntshiab hauv lub cev. rau ib qho tshuaj tiv thaiv.
Lub ntsiab lus tseem ceeb yog hais txog qhov kub thiab txias ntawm qhov system ntawm qhov tseem ceeb. Lub ntsiab lus tseem ceeb ntawm lub tshuab thermodynamic yog qhov kawg ntawm theem sib npaug ntawm qhov system. Nws yog qhov kub thiab txias uas cov kua tuaj yeem ua ke nrog nws lub vapor theem. Feem ntau, cov khoom uas peb suav tias yog cov khoom tseem ceeb yog qhov kub thiab txias thiab qhov tseem ceeb.
Cov Khoom Tseem Ceeb Tseem Ceeb yog dab tsi?
Cov khoom tseem ceeb tiag tiag yog cov khoom tseem ceeb ntawm lub kaw lus uas txiav txim siab thermodynamically. Cov khoom tseem ceeb tiag tiag yog qhov muaj txiaj ntsig zoo vim tias lawv suav nrog thermodynamically. Thiab nyob rau hauv kev xam cov nqi no, lawv txaus siab rau ob qho tib si quadratic thiab cubic daim ntawv nyob rau hauv lub expansion ntawm lub Helmholtz dawb lub zog raws li ib tug muaj nuj nqi ntawm mole tooj li xoom ntawm ib tug tseem ceeb point.

Pseudo Critical Properties yog dab tsi?
Pseudo cov khoom tseem ceeb yog cov khoom ntawm lub kaw lus uas pom tseeb kev koom tes ntawm txhua qhov ntshiab hauv ib qho system rau ib qho kev tawm tsam. Cov nqi no yog xam rau cov khoom sib tov xws li cov roj sib tov. Cov khoom no kuj muaj npe raws li qhov ntsuas qhov ntsuas. Tsis tas li ntawd, peb tuaj yeem piav qhia cov pseudo tseem ceeb ntawm cov khoom no raws li tus cwj pwm tsis tu ncua uas feem ntau tau txais los ntawm cov txheej txheem uas cuam tshuam nrog cov txheej txheem ntawm qhov nruab nrab ntawm cov khoom siv dawb huv hauv kev sib xyaw; tshwj xeeb tshaj yog, gaseous sib tov. Yog li ntawd, cov khoom tseem ceeb pseudo txawv ntawm cov khoom tseem ceeb tiag tiag.
Qhov txawv ntawm Qhov Tseeb thiab Pseudo Critical Properties yog dab tsi?
Lub ntsiab lus tseem ceeb feem ntau yog hais txog qhov kub thiab txias ntawm qhov system ntawm qhov tseem ceeb. Muaj ob hom khoom tseem ceeb; lawv yog cov khoom tseem ceeb tiag tiag thiab cov khoom pseudo tseem ceeb. Qhov sib txawv tseem ceeb ntawm qhov tseeb thiab pseudo cov khoom tseem ceeb yog qhov tseeb cov khoom tseem ceeb yog cov khoom tseem ceeb ntawm lub kaw lus uas tau txiav txim siab thermodynamically whereas pseudo cov khoom tseem ceeb yog qhov pom tseeb ntawm txhua qhov kev tivthaiv dawb huv hauv ib lub cev rau ib qho tshuaj tiv thaiv.
Ntxiv mus, cov khoom tseem ceeb yog suav nrog cov txheej txheem thermodynamic, thaum lub pseudo tseem ceeb cov khoom raug suav nrog cov qauv linear. Tsis tas li ntawd, cov khoom tseem ceeb muaj tseeb muab qhov muaj txiaj ntsig tiag tiag thaum pseudo cov khoom tseem ceeb muab cov txiaj ntsig pom tseeb. Yog li, qhov no yog lwm qhov sib txawv ntawm qhov tseeb thiab pseudo cov khoom tseem ceeb.
Cov infographic hauv qab no qhia txog qhov sib txawv ntawm qhov tseeb thiab pseudo cov khoom tseem ceeb hauv daim ntawv teev npe.
Summary – True vs Pseudo Critical Properties
Lub ntsiab lus tseem ceeb feem ntau yog hais txog qhov kub thiab txias ntawm qhov system ntawm qhov tseem ceeb. Cov khoom tseem ceeb tiag tiag yog cov khoom tseem ceeb ntawm lub kaw lus uas txiav txim siab thermodynamically. Pseudo cov khoom tseem ceeb, ntawm qhov tod tes, yog qhov pom tseeb ntawm txhua qhov kev tivthaiv dawb huv hauv lub cev rau ib qho tshuaj tiv thaiv. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm qhov tseeb thiab pseudo cov khoom tseem ceeb. Yog li ntawd, cov khoom tseem ceeb muaj tseeb muab qhov muaj txiaj ntsig tiag tiag thaum pseudo cov khoom tseem ceeb muab cov txiaj ntsig pom tseeb.
