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.
