Lub peb theem tseem ceeb ntawm cov teeb meem yog cov khoom, kua, thiab roj (vapor), tab sis lwm tus raug suav tias muaj, suav nrog crystalline, colloid, glassy, amorphous, thiab ntshav. theem. Thaum ib theem ntawm ib daim ntawv hloov mus rau lwm daim ntawv, ib theem hloov tau hais tias tau tshwm sim.
4 theem ntawm qhov teeb meem piav qhia txhua theem yog dab tsi?
Kev piav qhia (3) Muaj plaub theem: khoom, kua, roj, thiab ntshav. Cov khoom yog tsim los ntawm cov atoms uas nruj nreem khi ua ke, yog li lawv tuav lawv cov duab thiab muaj cov ntim ruaj khov. Cov kua dej tsis tau tuav ua ke kom nruj li cov khib nyiab.
Yuav ua li cas yog theem ntawm teeb meem piav qhia luv luv?
Cov khoom tuaj yeem muaj nyob hauv plaub theem (lossis xeev), khoom, kua, roj, thiab ntshav, ntxiv rau ob peb lwm theem siab xws li cov kua dej tseem ceeb thiab cov roj ntsha tsis zoo. Feem ntau, raws li cov khoom yog rhuab (los yog raws li lub siab txo), nws yuav hloov mus rau ib tug kua daim ntawv, thiab nws thiaj li yuav ua tau ib tug gas.
7 theem teeb meem yog dab tsi?
Khoom yog txhua yam uas yog tsim los ntawm atoms thiab molecules. (Studios, 1995). Xya lub xeev ntawm cov teeb meem uas kuv tab tom tshawb nrhiav yog Khoom, kua, Gases, Ionized Plasma, Quark-Gluon Plasma, Bose-Einstein Condensate thiab Fermionic Condensate.
8 theem teeb meem yog dab tsi?
