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.
Pom zoo:
Puas yog lub zog uas taug kev los ntawm hluav taws xob Ib qho piv txwv ntawm qhov no yog lub teeb?
2) Lub teeb yog cais raws li Electromabnerle RADIATION vim hluav taws xob thiab sib nqus teb vibrate nyob rau hauv lub teeb yoj. RADIANT ENERGY - yog lub zog uas taug kev los ntawm hluav taws xob. Ib qho piv txwv ntawm qhov no yog lub teeb. 4) Cov hluav taws xob cua sov, tseem hu ua _INFRARED WAVES w tsis tuaj yeem pom ntawm koj lub qhov muag tab sis tuaj yeem hnov ntawm koj cov tawv nqaij
Lub xeev ntawm teeb meem ntawm lub mantle yog dab tsi?
Lub mantle yog feem ntau-khoom ntawm lub ntiaj teb sab hauv. Lub mantle nyob nruab nrab ntawm lub ntiaj teb ntom ntom, super-rhuab core thiab nws nyias txheej txheej, lub crust. Lub mantle yog li 2,900 mais (1,802 mais) tuab, thiab ua rau 84% ntawm lub ntiaj teb tag nrho cov ntim
Yuav ua li cas lub abundance ntawm lub ntiaj teb no piv nrog cov abundance ntawm lub ntsiab nyob rau hauv tib neeg?
Oxygen yog cov khoom muaj ntau tshaj plaws hauv ntiaj teb thiab hauv tib neeg. Kev nplua nuj ntawm cov ntsiab lus uas tsim cov organic tebchaw nce hauv tib neeg thaum qhov kev nplua nuj ntawm metalloids nce hauv ntiaj teb. Cov ntsiab lus uas muaj ntau hauv ntiaj teb yog qhov tseem ceeb los txhawb txoj sia
Yuav ua li cas yog ib tug piv txwv ntawm ib tug multifactorial congenital teeb meem?
Feem ntau cov kab mob congenital congenital muaj xws li: Neural tube defects. Isolated hydrocephalus. Clubfoot. Cleft di ncauj thiab/los yog palate
Dab tsi yog ob lub xeev ntawm cov teeb meem pom thaum lub sij hawm melting?
Melting: solid to liquid. Condensation: gas toliquid. Vaporization: kua rau roj
