Teeb meem tshwm sim hauv plaub lub xeev: cov khoom khib nyiab , kua , cov pa , thiab plasma. Feem ntau lub xeev ntawm teeb meem ntawm ib yam khoom yuav raug hloov los ntawm kev ntxiv los yog tshem tawm cov cua sov los ntawm nws. Piv txwv li, qhov sib ntxiv ntawm cov cua sov tuaj yeem yaj cov dej khov rau hauv ua kua dej thiab hloov dej mus rau hauv chav.

Ib yam li ntawd, nws nug, 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 tsis compressible.
• Gas: Cov kua compressible.

Tsis tas li ntawd, qhov piv txwv tseem ceeb yog dab tsi? Teeb meem yog txhua yam uas muaj huab hwm coj thiab ntim (nyob qhov chaw). Xws li txhua yam uas tuaj yeem nyob qhov chaw thiab muaj huab hwm coj yog ib qho piv txwv ntawm teeb meem . Yeej lawv yog pab pawg ua peb lub xeev: khoom (phau ntawv cwj mem thiab lwm yam), kua (dej petrol thiab lwm yam) thiab roj (cov pa oxygen, co2 gas.

Hais txog qhov no, qhov piv txwv ntawm cov kua thiab roj yog dab tsi?

Dej, rau piv txwv , yog ib txwm ua los ntawm ob lub hydrogen atoms thiab ib qho oxygen atom. Txawm li cas los xij, nws tuaj yeem coj lub xeev ua kua , khov kho (ice), thiab gas (kub).

Cov piv txwv ntawm cov khoom yog dab tsi?

Piv txwv ntawm cov khoom khib nyiab yog cov rooj ntsev, cov suab thaj, dej khov, cov pa roj carbon dioxide khov (cov dej khov qhuav), iav, pob zeb, hlau feem ntau, thiab ntoo. Thaum a khov kho yog rhuab, lub atom los yog molecules tau kinetic zog.
