Viscosity yog tswj hwm los ntawm lub zog ntawm cov rog sib xyawsthiab tshwj xeeb tshaj yog los ntawm cov duab ntawm cov molecules ntawm cov kua. Cov kua uas nws cov molecules yog polar lossis tuaj yeem tsim cov ntawv cog lus hydrogen feem ntau yog nkig ntau dua li cov khoom tsis zoo sib xws.
Peb yam dab tsi ua rau cov kua sib txawv kom muaj viscosities sib txawv?
Long-chain molecules tseem tuaj yeem wriggle nyob ib ncig ntawm qhov kub thiab txias dua thiab yog li disentangle sai dua. 3.2 TSEEM CEEB NTAWM VISCOSITY Lub viscosity ntawm Newtonian kua yog cuam tshuam los ntawm kub, siab, thiab, nyob rau hauv cov ntaub ntawv ntawm kev daws teeb meem thiab sib tov, los ntawm muaj pes tsawg leeg.
Vim li cas cov kua muaj qhov sib txawv?
Nyob rau hauv qhov kev nthuav qhia no koj kawm txog cov kua sib txawv li cas muaj cov viscosities sib txawv. Qee cov kua dej khov ntau dua li lwm tus. Qhov no txhais tau tias lawv yog tuab dua thiab ntws yooj yim dua. Hais txog cov khoom, viscosity yog yooj yim npaum li cas cov khoom ntawm cov kua txav mus rau ib leeg.
Dab tsi cuam tshuam rau viscosity ntawm cov kua?
Dab tsi cuam tshuam rau viscosity? Viscosity yog tsis kam mus ntws. Rau cov kua, feem ntau qhov loj dua qhov sib xyaw ua ke (IMF) qhov siab dua qhov viscosity. Lwm yam uas cuam tshuam rau viscosity yog qhov kub thiab txias thiab cov duab ntawm cov molecule.
Dab tsi txiav txim siab qhov viscosity ntawm cov kua dej?
Viscosity yog cuam tshuam los ntawm kev sib xyaw ntawm cov cruderoj, qhov kub thiab txias, yaj cov ntsiab lus roj, thiab lub siab. Raws li qhov kub nce, qhov viscosity yuav txo.
