YDiffusion vs Osmosis
Diffusion thiab Osmosis yog cov txheej txheem ntawm lub cev uas feem ntau tsis meej pem nrog ib leeg thiab tib neeg pom tias nws nyuaj rau kev sib txawv ntawm ob. Cov no yog cov txheej txheem uas pom nyob rau hauv cov xwm txheej thiab muaj feem xyuam nrog kev txav ntawm atoms thiab molecules los ntawm thaj chaw siab dua mus rau thaj tsam ntawm qhov qis dua. Cov no yog cov ntsiab lus uas ib txwm qhia hauv physics, chemistry thiab biology thiab tuav qhov tseem ceeb hauv kev tshawb fawb. Tag nrho cov txheej txheem hauv cov xwm txheej tau piav qhia los ntawm lub hauv paus ntawm kev txav ntawm atoms thiab molecules thiab ob lub ntsiab lus zoo nkauj suav tag nrho cov txheej txheem ntawm qib microscopic.
Tau hais tias ob qho tib si diffusion thiab osmosis cuam tshuam nrog kev txav ntawm cov molecules, ob qho tib si sib piv li cas thiab dab tsi yog qhov txawv ntawm ob lub tswv yim. Thaum diffusion cuam tshuam nrog kev txav ntawm ib qho tshuaj los ntawm ib qho chaw mus rau lwm qhov, osmosis cuam tshuam nrog kev txav ntawm tsuas yog dej hla ib daim nyias nyias. Qhov no ua kom pom tseeb tias nws tsuas yog dej uas tuaj yeem ua rau osmosis. Xws li nws tuaj yeem hais tias osmosis yog hom tshwj xeeb ntawm kev sib kis. Ib qho piv txwv ntawm osmosis yog thaum peb xav nqhis dej tom qab noj ib yam dab tsi qab ntsev li cov ntsev no nqus dej los ntawm cov hlwb ntawm lub cev.
Diffusion tshwm sim yam tsis muaj daim nyias nyias thaum osmosis tshwm sim hla ib daim nyias nyias xwb.
Yog hais tias qhov diffusion molecules tuaj yeem ntws mus rau txhua qhov kev taw qhia, thaum nyob hauv osmosis, qhov ntws ntawm cov molecules yog nyob rau hauv ib qho kev taw qhia nkaus xwb.
Diffusion raws li cov txheej txheem tsis nyob hauv cov kua thiab txawm tias cov pa tawm mus. Ib qho piv txwv zoo ntawm gaseous diffusion yog chav tshuaj tsuag uas tau hnov ntawm lwm lub ces kaum ntawm chav tsev. Osmosis tsuas tuaj yeem tshwm sim hauv cov kev daws teeb meem uas muaj dej hauv cov xwm txheej.
Osmosis qeeb qeeb hauv qhov xwm txheej thaum sib kis tshwm sim ntawm tus nqi nrawm dua.
Diffusion tshwm sim nyob rau hauv ob qho tib si luv luv thiab ntev nyob qhov twg osmosis tuaj yeem tshwm sim dhau qhov kev ncua luv xwb.
Diffusion tsis yog nyob ntawm dej kom ntws ntawm cov molecules, thaum osmosis tsuas yog nyob hauv dej xwb.
Ib qhov zoo sib xws ntawm osmosis thiab diffusion yog tias lawv yog ob qho tib si nyob rau hauv qhov xwm txheej thiab tsis muaj lub zog sab nraud yuav tsum tau rau kev ntws ntawm cov molecules ntawm ib qhov chaw mus rau lwm qhov. Ob qho tib si diffusion thiab osmosis ua lub luag haujlwm tseem ceeb hauv cov kab mob muaj sia kom ua tiav lub xeev ntawm kev sib npaug sab hauv. Nyob rau hauv cov ntaub ntawv ntawm cov nroj tsuag, osmosis yog tsim nyog rau cell membranes nqus dej thiab lwm yam kua, thaum diffusion tso cai rau dej, oxygen thiab carbon dioxide mus txog. Hauv cov tsiaj txhu (xws li tib neeg), osmosis tseem ceeb dua vim nws tso cai rau kev faib cov as-ham thiab tso cov khoom pov tseg.
Summary:
Ob qhov kev nthuav dav thiab osmosis koom nrog kev txav ntawm cov molecules los ntawm thaj chaw siab concentration mus rau thaj chaw uas tsis muaj concentration.
Thaum kev sib kis tshwm sim los ntawm cov khoom, kua thiab roj, osmosis tsuas yog nyob hauv dej xwb.
Osmosis yog hom tshwj xeeb ntawm kev sib kis
Diffusion tuaj yeem tshwm sim thoob plaws txhua qhov kev ncua deb, thaum osmosis tshwm sim hla cov kab mob permeable dhau qhov deb.
