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.

Darwin tau soj ntsuam dab tsi txog hom ntawm cov Islands tuaj?
Thaum nws mus ntsib Galapagos Islands, Charles Darwin nrhiav tau ntau hom finches uas txawv ntawm cov kob mus rau ib kob, uas pab nws tsim nws txoj kev xav ntawm kev xaiv ntuj
Qhov kev piav qhia txog dab tsi Darwin tau soj ntsuam?
Charles Darwin yog ib tug naturalist uas tau soj ntsuam ntau yam ntawm xwm thiab sau nws cov tswv yim rau hauv ib txoj kev xav hu ua natural selection. Tshwj xeeb tshaj yog, nws txoj kev xav yog hu ua txoj kev xav ntawm evolution los ntawm kev xaiv ntuj vim nws piav qhia txog txoj hauv kev uas cov pej xeem tuaj yeem hloov pauv
Dab tsi yog qhov teeb meem loj tshaj plaws ntawm kev siv cov kev tshawb fawb txog kev sib raug zoo?
Tej yam tsis zoo los yog kev tshawb fawb txog kev sib raug zoo muaj xws li: a. Lawv tsis tuaj yeem siv los tsim kom muaj kev sib raug zoo-thiab-tshuaj los yog kev coj ntawm kev cuam tshuam
Hom microscope twg tuaj yeem siv los soj ntsuam cov hlwb thiab cov ntaub so ntswg?
Lub tshuab hluav taws xob hauv lub hlwb tsis tuaj yeem soj ntsuam siv lub tshuab ntsuas hluav taws xob vim tias cov qauv muab tso rau hauv lub tshuab nqus tsev. Muaj ob hom electron microscope: qhov kis tau tus mob electron microscope (TEM) yog siv los tshuaj xyuas cov nyias nyias los yog ntu ntawm cov hlwb lossis cov ntaub so ntswg
Cov kev soj ntsuam soj ntsuam dab tsi qhia tias muaj kev hloov tshuaj lom neeg tshwm sim?
Kev soj ntsuam uas qhia tias muaj kev hloov pauv tshuaj muaj xws li kev hloov xim, hloov pauv kub, lub teeb muab tawm, tsim ua npuas, tsim cov nag lossis daus, thiab lwm yam
