Teeb meem yog txhua yam nyob ib puag ncig koj. Atoms thiab cov tebchaw yog tag nrho ua los ntawm qhov me me ntawm teeb meem . Cov atoms mus ua tej yam uas koj pom thiab kov txhua hnub. Teeb meem txhais tau tias yog txhua yam uas muaj huab hwm coj thiab siv qhov chaw (nws muaj ntim). Volume yog tus nqi ntawm qhov chaw ib yam dab tsi occupies.
Tsuas yog li ntawd, qhov teeb meem luv luv yog dab tsi?
Teeb meem yog ib yam khoom uas muaj inertia thiab occupies lub cev qhov chaw. Raws li niaj hnub physics, teeb meem muaj ntau hom particles, txhua tus nrog loj thiab loj. Cov piv txwv zoo tshaj plaws ntawm cov khoom siv yog electron, proton thiab neutron. Kev sib xyaw ntawm cov khoom no tsim cov atoms.
Dab tsi yog qhov tseem ceeb hauv science qib 4? Science/State of Matter. Txhua yam nyob ib puag ncig peb yog hu ua teeb meem. Teeb meem yog txhua yam uas occupies qhov chaw thiab muaj pawg . Qee qhov piv txwv ntawm cov teeb meem yog ntoo, dej, thiab huab cua.
Ib yam li ib tug yuav nug, dab tsi yog qhov tseem ceeb ntawm qib 5 kev tshawb fawb?
Teeb meem yog txhua yam uas muaj qhov hnyav thiab siv qhov chaw. Txhua yam koj tuaj yeem pom thiab kov yog tsim los ntawm teeb meem . Teeb meem muaj nyob rau hauv peb yam tseem ceeb: khoom, kua, thiab gases. Nws kuj muaj cov khoom uas peb tuaj yeem piav qhia los ntawm qhov ntom ntom, solubility, conductivity, magnetism, thiab lwm yam.
Dab tsi yog qhov tseem ceeb hauv science rau qib 2?
Teeb meem . Nws yog txhua yam nyob ib puag ncig koj! Nws yog txhua yam uas muaj huab hwm coj thiab siv qhov chaw. Cov huab, dej hiav txwv, thiab ntoo, nws yog tag nrho teeb meem !

Qhov ntim ntawm qhov teeb meem yog dab tsi?
Mass yog tus nqi ntawm cov khoom uas muaj, thiab ntim yog qhov chaw uas qhov teeb meem yuav siv. Cov khoom yog qhov yooj yim rau kev paub
Dab tsi yog qhov txawv ntawm qhov 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 nyob rau hauv daim ntawv ntawm cov tsis muaj sia nyob cov as-ham tseem ceeb rau cov kab mob nyob. Yog li koj pom, teeb meem yog rov ua dua tshiab hauv ecosystem. Tsis zoo li qhov teeb meem, lub zog tsis rov siv dua los ntawm qhov system
Dab tsi yog qhov minuend hauv qhov teeb meem rho tawm?
Minuend. Thawj tus lej hauv kev rho tawm. Tus lej uas lwm tus lej (lub Subtrahend) yuav raug rho tawm. Piv txwv li: hauv 8 − 3 = 5,8 yog minuend
Elementary daws lo lus teeb meem li cas?
Nov yog xya lub tswv yim uas kuv siv los pab cov tub ntxhais kawm daws cov teeb meem lo lus. Nyeem tag nrho lo lus teeb meem. Xav txog lo lus teeb meem. Sau rau lo lus teeb meem. Kos ib daim duab yooj yim thiab sau nws. Kwv yees cov lus teb ua ntej daws. Tshawb xyuas koj txoj haujlwm thaum ua tiav. Xyaum lo lus teeb meem ntau zaus
Dab tsi yog qhov teeb meem ntawm lub teeb nyob rau hauv lub ntuj hmo ntuj hu ua?
Gegenschein, tseem hu ua Counterglow, oval thaj ntawm faint luminosity raws nraim rau lub hnub nyob rau hauv lub hmo ntuj. Lub thaj ntawm lub teeb yog li faint nws tuaj yeem pom tsuas yog thaum tsis muaj lub hli, nyob deb ntawm lub nroog teeb, thiab nrog lub qhov muag yoog rau qhov tsaus ntuj
