Qhov Tseem Ceeb Qhov Sib Txawv - Qhov Tseem Ceeb vs Triple Point
qhov taw qhia tseem ceeb thiab triple point yog cov ntsiab lus siv los piav qhia qhov kub thiab txias ntawm ob lossis ntau theem ntawm cov khoom tuaj yeem ua ke nrog ib leeg. Lub ntsiab lus tseem ceeb yog qhov xwm txheej ntawm cov kua thiab vapor theem ntawm tib yam khoom sib koom ua ke. Lub ntsiab lus triple yog qhov xwm txheej uas tag nrho peb theem ntawm cov teeb meem tuaj yeem sib koom ua ke. Qhov sib txawv tseem ceeb ntawm qhov taw tes tseem ceeb thiab triple point yog qhov tseem ceeb piav qhia txog kev sib koom ua ke ntawm ob theem ntawm tib yam khoom thaum triple point piav qhia txog kev sib koom ua ke ntawm peb theem ntawm tib yam khoom.
Lub ntsiab lus tseem ceeb yog dab tsi?
Lub ntsiab lus tseem ceeb ntawm ib yam khoom yog qhov kawg ntawm theem kev sib npaug ntawm cov khoom ntawd. Ib theem equilibrium nkhaus los yog daim duab qhia theem yog daim duab ntawm lub siab piv rau qhov kub thiab txias nyob rau hauv uas cov theem hloov ntawm cov khoom yog qhia. Qhov no qhia tau hais tias qhov kub thiab qhov siab ntawm cov khoom muaj nyob hauv cov khoom, kua lossis roj. Lub ntsiab lus tseem ceeb yog qhov kub thiab txias uas cov kua thiab vapor theem coexist.
Daim duab 01: Daim duab Phaj uas qhia Ob Qhov Tseem Ceeb thiab Triple Point
Qhov kub thiab siab ntawm qhov tseem ceeb yog lub npe hu ua qhov kub thiab txias (Tc) thiab lub siab tseem ceeb (Pc). Raws li pom nyob rau hauv daim duab saum toj no, cov kab ntawm ob theem yog hu ua ciam teb. Lub ntsiab lus tseem ceeb qhia txog lub ntsiab lus ntawm txoj kab ciam teb ploj mus.
Kev paub qhov tseem ceeb ntawm cov khoom yog qee zaum tseem ceeb heev. Piv txwv li, cov pa roj tsis tuaj yeem raug condensed ntawm qhov kub thiab txias siab tshaj nws qhov tseem ceeb. Qhov no yog vim hais tias cov intermolecular rog ntawm cov roj molecule tsis muaj zog ntawm qhov kub siab heev txij li thaum lub kinetic zog ntawm cov molecules yog nce.
Muaj ob hom ntawm qhov tseem ceeb;
Liquid-Vapour Critical Point
Qhov no yog ib qho tseem ceeb ntawm qhov chaw vapor ntawm ib yam khoom nyob nrog nws daim ntawv ua kua. Qhov tseem ceeb ntawm cov dej yog ntawm 647 K thiab 22.064 MPa.
Liquid-Liquid Critical Point
hom ntsiab lus tseem ceeb no yog txhais rau kev daws teeb meem. Nws yog qhov kub thiab txias ntawm qhov sib tov sib xyaw ua ke rau hauv ob theem ua kua sib txawv.
Triple Point yog dab tsi?
Qhov taw tes triple yog qhov kub thiab txias ntawm cov khoom, kua, thiab vapor theem ntawm ib qho khoom sib npaug hauv qhov sib npaug. Nws piav qhia txog qhov tshwj xeeb thermodynamic lub xeev ntawm matte. Qee zaum, qhov taw tes triple yuav koom nrog ntau tshaj ib theem khoom thaum muaj cov tshuaj polymorphs. Nyob rau hauv daim duab qhia theem, triple point yog qhov taw tes uas tag nrho peb txoj kab ciam teb sib ntsib. Qee qhov piv txwv ntawm triple cov ntsiab lus tau muab hauv qab no.
Dab tsi yog qhov zoo sib xws ntawm Cov Ntsiab Lus Tseem Ceeb thiab Triple Point?
- Ob qho tseem ceeb Point thiab Triple Point piav qhia qee qhov kub thiab txias.
- Ob Lub Ntsiab Tseem Ceeb thiab Triple Point piav qhia txog kev sib npaug ntawm qhov twg ob lossis ntau lub cev lub cev ntawm cov khoom sib koom ua ke.
Qhov txawv ntawm Qhov Tseem Ceeb thiab Triple Point yog dab tsi?

Summary – Critical Point vs Triple Point
Lub ntsiab lus tseem ceeb ntawm ib yam khoom yog qhov kawg ntawm theem kev sib npaug ntawm cov khoom uas muab qhov kub thiab txias ntawm cov kua thiab vapor theem ntawm cov khoom tuaj yeem ua ke nrog ib leeg. Qhov triple point muab qhov kub thiab txias uas tag nrho peb theem ntawm cov teeb meem tuaj yeem ua ke nrog ib leeg. Qhov sib txawv ntawm qhov tseem ceeb thiab qhov triple point yog qhov tseem ceeb piav qhia txog kev sib koom ua ke ntawm ob theem ntawm tib yam khoom thaum triple point piav qhia txog kev sib koom ua ke ntawm peb theem ntawm tib yam khoom.
