Teeb meem tuaj yeem muaj nyob hauv ib qho ntawm peb lub ntsiab xeev : khoom, kua, los yog roj. Khoom teeb meem yog tsim ntawm nruj nreem ntim cov khoom . Ib qho khoom yuav khaws nws cov duab; tus cov khoom tsis muaj kev ywj pheej mus ncig. Ua kua teeb meem ua ntawm ntau loosely packed cov khoom.
Ntawm no, 12 lub xeev ntawm teeb meem yog dab tsi?
Classical xeev ntawm teeb meem feem ntau yog summarized li: khoom, ua kua , gas , thiab ntshav ntshav.
Cov xeev qis zog
- Khoom: Ib qho khoom tuav lub cev thiab ntim yam tsis muaj lub thawv.
- Liquid: Feem ntau cov kua uas tsis yog compressible.
- Gas: Cov kua compressible.
Tsis tas li ntawd, lub xeev ntawm cov teeb meem twg tuaj yeem ntws tau? Cov molecules tuaj yeem txuas ntxiv mus nrog kev hwm ntawm ib leeg. Qhov no txhais tau tias kua tuaj yeem ntws tau yooj yim, tab sis tsis zoo li cov pa roj. Cov kua dej yuav nyiam coj cov duab ntawm lub thawv uas lawv nyob hauv. Cov kua dej Feem ntau tsis tshua ntom dua cov khib nyiab, tab sis denser dua gases.
Yog li ntawd, dab tsi yog particles ntawm teeb meem?
Lub tswv yim a: Txhua qhov teeb meem yog tsim los ntawm cov khoom hu ua atoms thiab molecules (raws li opposed to ua nruam los yog cia li nrog hais). Nyob rau nplooj ntawv nram qab no, lub tswv yim tau hais tias yog ib qho ntawm plaub lub ntsiab lus hauv Dalton txoj kev xav: Txhua yam teeb meem yog tsim los ntawm cov me me, cov khoom tsis sib xws hu ua atoms ” (nqe 158s).
Muaj pes tsawg lub xeev ntawm teeb meem?
Lub tsib theem ntawm teeb meem . Muaj plaub lub ntuj xeev ntawm teeb meem : Khoom, kua, roj thiab plasma. Qhov thib tsib xeev yog tus txiv neej tsim Bose-Einstein condensates. Nyob rau hauv ib qho khoom, cov khoom yog ntim nruj ua ke kom lawv tsis txav mus los ntau.

Dab tsi yog qhov txawv ntawm qhov ntws ntawm cov teeb meem thiab lub zog hauv ib qho ecosystem?
Muaj qhov sib txawv tseem ceeb hauv txoj kev lub zog thiab cov teeb meem ntws los ntawm ib qho ecosystem. Cov teeb meem ntws los ntawm ecosystem hauv daim ntawv ntawm cov khoom noj uas tsis muaj sia nyob uas tseem ceeb rau cov kab mob nyob. Yog li koj pom, teeb meem yog rov siv dua hauv ecosystem. Tsis zoo li qhov teeb meem, lub zog tsis rov siv dua los ntawm qhov system
Dab tsi yog qhov yuam kev loj tshaj plaws yog tias Irina ntsuas qhov ntev ntawm nws lub qhov rais li 3.35 feet qhov yuam kev loj tshaj plaws yog taw?
Kev daws: Qhov yuam kev loj tshaj plaws hauv kev ntsuas ntsuas tau txhais tias yog ib nrab ntawm qhov ntsuas ntsuas
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Yuav ua li cas tshwm sim rau qhov teeb meem uas ploj ntawm txhua theem ntawm cov khoom noj khoom haus?
Lub zog tau dhau los ntawm cov khoom noj khoom haus los ntawm ib qib trophic mus rau lwm qhov. Txawm li cas los xij, tsuas yog kwv yees li 10 feem pua ntawm tag nrho lub zog khaws cia hauv cov kab mob ntawm ib qib trophic tau raug xa mus rau cov kab mob ntawm qib trophic tom ntej. Cov seem ntawm lub zog yog siv rau cov txheej txheem metabolic lossis poob rau ib puag ncig raws li cua sov
Txoj cai thermodynamic twg hais tias koj Tsis tuaj yeem hloov 100 feem pua ntawm cov cua sov rau hauv cov khoom siv hluav taws xob ntawm cov lus teb xaiv?
