Qhov sib txawv tseem ceeb ntawm cov pa oxygen thiab cov pa oxygen yog cov pa oxygen ua kua muaj qhov sib piv me me ntawm ob lub pa oxygen molecules, hos cov pa oxygen muaj qhov sib nrug deb ntawm cov pa oxygen molecules.
Oxygen yog ib qho tshuaj tseem ceeb heev. Nws tuaj yeem tshwm sim hauv ob txoj hauv kev loj xws li kua oxygen thiab cov pa oxygen. Ntawm lawv, cov pa oxygen yog qhov tseem ceeb tshaj plaws thiab tseem ceeb ntawm cov pa oxygen, hos cov pa oxygen muaj kev xav tau kev lag luam.
Ua Kua Oxygen yog dab tsi?
Ua kua oxygen yog cov kua dej ntawm molecular oxygen. Nws muaj cov kev siv loj hauv aerospace, gas industries, thiab submarines. Peb tuaj yeem sau cov pa oxygen no li Lox, LOX lossis Lox. Xyoo 1926, Robert H. Goddard tau siv cov pa oxygen no ua cov oxidizer hauv nws thawj qhov kev tsim ua kua roj foob pob hluav taws.
Daim duab 01: Qhov tshwm sim ntawm cov kua Oxygen
Feem ntau, cov pa oxygen ua kua muaj lub teeb xiav xim. Cov khoom no yog paramagnetic heev; yog li ntawd, peb tuaj yeem ua rau nws raug tshem tawm ntawm cov ncej ntawm cov hlau nplaum muaj zog. Nws qhov ceev yog li 1141 g / L, uas yog me ntsis denser dua li cov dej ua kua. Ntxiv mus, cov khoom no yog cryogenic, muaj qhov tsis tshua muaj khov thiab kub kub. Vim qhov no cryogenic xwm ntawm cov kua oxygen, nws tuaj yeem ua rau cov khoom nws kov kom nkig heev.
Tsis tas li ntawd, cov pa oxygen ua kua yog lub zog oxidizing tus neeg sawv cev. Yog li, cov ntaub ntawv organic tuaj yeem hlawv sai thiab nquag nyob rau hauv muaj cov kua oxygen. Qee cov ntaub ntawv (xws li thee) tuaj yeem muab cov nplaim taws uas tsis tuaj yeem pom yog tias lawv tau tsau rau hauv cov pa oxygen.
Thaum xav txog cov qauv ntawm cov pa oxygen, nws tau ntseeg tias muaj tetraoxygen molecules, O4, uas tau kwv yees li ntawd txhawm rau tiv thaiv Curie txoj cai. Txawm li cas los xij, raws li qee lub computer simulations niaj hnub no, tsis tuaj yeem muaj qhov ruaj khov O4 molecules hauv kua oxygen. Yog li ntawd, tam sim no nws tau ntseeg tias muaj O2 molecules, uas muaj feem xyuam rau hauv cov khub hauv qab kev sib tw sib tw uas tuaj yeem tsim O4 ntu ntu.
Gas Oxygen yog dab tsi?
Gas oxygen yog lub xeev gaseous ntawm molecular oxygen. Nyob rau hauv cov xwm txheej txheem, cov pa oxygen yog cov xim tsis muaj xim, tsis muaj ntxhiab, thiab tsis muaj roj uas muaj cov mis molecular O2. Thaum muab piv rau kev sib cais ntawm cov pa thiab nitrogen hauv dej, cov pa oxygen zoo li yaj sai dua. Nws yooj yim yaj hauv dej tshiab piv rau cov dej hiav txwv. Txawm li cas los xij, qhov dej solubility ntawm cov pa oxygen nyob ntawm qhov kub thiab txias vim tias, ntawm qhov kub thiab txias, solubility yuav qis.
Daim duab 02: Siv cov pa roj carbon monoxide rau Photosynthesis
Tsis tas li ntawd, cov pa oxygen yog cov tshuaj lom neeg ntau tshaj plaws los ntawm huab cua hauv ntiaj teb biosphere, huab cua, hiav txwv, thiab av. Hauv lub ntiaj teb, nws yog 3 rdfeem ntau cov tshuaj lom neeg (los tom qab hydrogen thiab helium). Cov ntsiab lus siab ntawm oxygen hauv peb lub ntiaj teb ua rau nws txawv ntawm lwm cov ntiaj chaw ntawm Lub Hnub Ci thiab yog qhov laj thawj tshaj plaws rau lub neej hauv ntiaj teb. Cov pa oxygen hauv ntiaj teb ua rau lub voj voog oxygen, uas piav qhia txog kev txav ntawm cov pa hauv thiab nruab nrab ntawm huab cua, biosphere thiab lithosphere.
Dab tsi yog qhov sib txawv ntawm Kua Oxygen thiab Gas Oxygen?
Raws li lawv lub npe txhais, cov pa oxygen yog cov kua dej ntawm cov pa oxygen molecular, thaum cov pa oxygen yog lub xeev gaseous ntawm molecular oxygen. Qhov sib txawv tseem ceeb ntawm cov pa oxygen thiab cov pa oxygen yog tias cov pa oxygen muaj qhov sib piv me me ntawm ob lub pa oxygen molecules, hos cov pa oxygen muaj qhov sib nrug deb ntawm cov pa oxygen molecules. Ntxiv mus, hais txog qhov tsos, cov kua oxygen yog xim daj ntseg xim, paramagnetic, thiab cov khoom siv cryogenic uas tuaj yeem ua rau lwm cov ntaub ntawv nkig, hos cov pa oxygen tsis muaj xim, tsis muaj xim, tsis muaj ntxhiab tsw ntawm cov qauv kub thiab siab.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm cov pa oxygen thiab cov pa oxygen hauv daim ntawv tabular.
Summary – Kua Oxygen vs Gas Oxygen
Ua kua oxygen yog cov kua dej ntawm molecular oxygen. Cov pa oxygen yog lub xeev gaseous ntawm molecular oxygen. Qhov sib txawv tseem ceeb ntawm cov pa oxygen thiab cov pa oxygen yog tias cov pa oxygen muaj qhov sib piv me me ntawm ob lub pa oxygen molecules, hos cov pa oxygen muaj qhov sib nrug deb ntawm cov pa oxygen molecules.
