Qhov no txhais tau tias ua kua particles yog sib nrug thiab ua tau txav tau yooj yim dua. Txij li cov hais ua tau mov, ua kua yuav ntws thiab coj cov duab ntawm nws lub thawv. Qhov no yog vim lub zog ntawm kev nyiam ntawm cov dej hauv dej rub cov khoom ntawm qhov chaw ua ke.
Ib yam li ntawd, nws raug nug, vim li cas cov kua dej ntws tau yooj yim?
A ua kua feem ntau ntws yooj yim vim nws qhov chaw intermolecular. Ntxiv mus, kua Yog li ntawd, muaj ib tug weakerintermolecular quab yuam ntawm attraction kua dej ntws.
Ib yam li ntawd, vim li cas cov kua thiab cov pa roj ntws? Kua thiab roj hu ua kua vim lawv ua tau ua rau ntws , los yog txav. Hauv cov kua dej, lawv tus kheej yog nyob rau hauv tas li, random txav, sib tsoo nrog ib leeg thiab nrog cov phab ntsa ntawm txhua lub thawv. Cov lus tsa suab ntawmsolids thiab cov tshuaj tiv thaiv rau sab nraud rog tau piav qhia los ntawm Newton's Laws of Motion.
Kuj Paub, vim li cas cov kua dej ntws?
Cov kua dej ntws vim hais tias lawv cov atoms (los yog cov molecules) tsis tuav lub kaw ntom nti nrog ib leeg, tab sis tuaj yeem "slipand slide" thoob plaws qhov chaw. Qhov "siab" los ntawm cov pa roj tau los ntawm qhov kev txav txav ntawm cov theatoms / molecules sib tsoo nrog cov phab ntsa uas muaj thegas.
Vim li cas cov kua dej tseem ceeb?
Yuav kom ciaj sia, lub cev siv nyob rau hauv tseem ceeb cov khoom siv los ua lub zog, thaum kaw tawm cov tshuaj lom xws li cov khoom pov tseg. Hauv qhov no, dej yog qhov tseem ceeb tsuas yog vim nws yog ib qho ua kua ntawm lub ntiaj teb-zoo li kub.
Pom zoo:
Cov kua dej thiab hom kua dej yog dab tsi?
Cov kua dej tuaj yeem muab faib ua plaub yam yooj yim. Cov kua dej zoo tagnrho. Cov kua dej tiag tiag. Newtonian kua dej. Tsis yog-Newtonian Fluid
Lub kinetic txoj kev xav ntawm cov teeb meem cuam tshuam li cas rau cov kua dej thiab cov pa roj?
Lub kinetic molecular txoj kev xav ntawm cov teeb meem hais tias: Cov teeb meem yog tsim los ntawm cov khoom uas hloov mus tas li. Tag nrho cov khoom muaj lub zog, tab sis lub zog sib txawv nyob ntawm qhov ntsuas kub ntawm cov qauv ntawm cov teeb meem nyob hauv
Vim li cas cov kua siv lead ua kua hloov xim nrog kub?
Cov molecules hauv cov kua siv lead ua kua tuaj yeem txav mus los ntawm nws tus kheej, xws li hauv cov kua, tab sis nyob twj ywm me ntsis, xws li hauv cov khoom siv lead ua (khoom). Cov kua siv lead ua kua no teb rau kev hloov pauv ntawm qhov kub thiab txias los ntawm kev hloov xim. Raws li qhov kub thiab txias, lawv cov xim hloov ntawm liab mus rau txiv kab ntxwv, daj, ntsuab, xiav, thiab ntshav
Vim li cas cov dej ntws tawm ntawm lub qhov tsua no xim dawb?
Lub qhov tsua tub txib saum ntuj noj cov kab mob hauv cov dej ntws ceev ceev kom lawv tuav nrog cov hooks microscopic ntawm lawv cov fins. Cov dej ntws tawm ntawm Villa Luz qhov tsua hauv Mexico yog xim dawb nrog sulfuric acid
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
