Lub cev muaj zog tuaj yeem ua tau pom los yog ntsuas tsis hloov qhov muaj pes tsawg leeg ntawm teeb meem . Lub cev muaj zog yog siv los saib thiab piav txog qhov teeb meem . Lub cev muaj zog muaj xws li: zoo li, kev ntxhib los mos, xim, tsw, melting point, boiling point, ntom, solubility, polarity, thiab lwm yam.

Raws li txoj cai, koj piav qhov teeb meem li cas?

Teeb meem yog cov khoom nyob ib puag ncig koj 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).

Qhov thib ob, dab tsi yog lub cev khoom thiab piv txwv? Piv txwv ntawm lub cev muaj zog yog: xim, tsis hnov tsw, khov point, boiling point, melting point, infrared spectrum, attraction (paramagnetic) los yog repulsion (diamagnetic) rau hlau nplaum, opacity, viscosity thiab ceev. Qhov ntau khoom peb tuaj yeem txheeb xyuas cov khoom, qhov zoo dua peb paub qhov xwm txheej ntawm cov khoom ntawd.

qhov teeb meem yog dab tsi muab piv txwv?

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. Tus paub zoo tshaj plaws piv txwv ntawm cov khoom hais yog electron, proton thiab neutron.

Dab tsi yog yam ntxwv ntawm peb lub xeev ntawm teeb meem?

Teeb meem tuaj yeem nyob hauv ib qho peb lub ntsiab xeev : khoom, kua, los yog roj. Khoom teeb meem yog tsim los ntawm nruj packed hais. Ib qho khoom yuav khaws nws cov duab; cov hais tsis pub dawb txav mus los. Ua kua teeb meem yog ua los ntawm ntau loosely packed hais.
