Khoom muaj peev xwm diffuse hauv kua raws li lawv nyem rau hauv molecular gap ntawm kua , xws li ntsev hauv dej, txawm li cas los xij cov ntsev ntau dhau ua rau cov ntsev tsis yaj vim qhov khoob ntawm cov molecules twb tau ntim lawm.

Cia li xav txog qhov no, yuav ua li cas diffusion tshwm sim hauv cov kua?

Diffusion kuj tuaj yeem tshwm sim hauv kua . Qhov no yog vim cov particles hauv kua tuaj yeem txav mus los ib leeg, uas txhais tau hais tias thaum kawg lawv sib xyaw ua ke. Piv txwv li, poov tshuaj manganate (VII) yog xim liab. Yog hais tias koj muab ib tug crystal ntawm nws mus rau hauv lub hub ntawm dej, cov xim liab doog kis maj mam los ntawm dej.

Tsis tas li ntawd, yuav ua li cas diffusion tshwm sim hauv cov khib nyiab? Diffusion tuaj yeem tshwm sim hauv gases, kua, los yog cov khoom khib nyiab . Hauv cov khoom khib nyiab , tshwj xeeb, tshwm sim diffusion vim yog thermally-activated random motion ntawm atoms - tshwj tsis yog cov khoom nyob rau ntawm qhov kub tsis txias (zero Kelvin), tus neeg atoms kom vibrating thiab nws thiaj li txav mus rau hauv cov khoom.

Raws li qhov no, cov khoom puas tuaj yeem tawg hauv cov pa roj?

Thaum rau qee yam cov khoom khib nyiab qhov chaw no txaus los kho cov molecule thaum rau qee qhov lawv xav tau ntau qhov chaw uas lawv nkag mus cov pa yog li ntawd cov khoom khib nyiab tau diffused hauv cov pa thiab tsis nyob hauv cov kua.

Cov txheej txheem ntawm diffusion hauv cov kua sib txawv li cas hauv cov khoom?

Diffusion hauv Khoom , Cov kua dej , Gases thiab Jelly. Diffusion hauv kua : Thaum cov tshuaj yaj hauv kua (zoo li ntsev yaj hauv dej) cov khoom kis tau tawm. Diffusion hauv cov khoom khib nyiab : Diffusion tsis tshwm sim hauv cov khoom khib nyiab vim hais tias cov khoom tsis pub dawb txav mus los thiab yog li lawv tsis tuaj yeem sib xyaw.
