Qhov ntom ntom yog ib qho tseem ceeb ntawm lub cev. Qhov ntom yog qhov loj ntawm cov khoom hauv ib chav tsev ntim. Volume yog tus nqi ntawm qhov chaw ib yam khoom occupies. Chemical Properties - Cov no yog cov khoom uas tuaj yeem pom los ntawm kev hloov pauv tus kheej ntawm cov khoom.

Ua raws li qhov no hauv kev txiav txim siab, ob yam tseem ceeb twg txiav txim siab txog lub xeev teeb meem?

Ob yam txiav txim seb cov khoom puas yog ib qho khoom, kua, lossis roj:

  • Lub zog kinetic ntawm cov khoom (atoms, molecules, lossis ions) uas tsim cov khoom. Kinetic zog nyiam ua kom cov khoom txav sib nrug.
  • Qhov ntxim nyiam intermolecular rog ntawm cov khoom uas nyiam kos cov khoom ua ke.

Ib tug kuj nug, koj tuaj yeem txheeb xyuas qhov teeb meem li cas? Teeb meem tuaj yeem raug cais raws li lub cev thiab tshuaj lom neeg. Teeb meem yog txhua yam uas occupies qhov chaw thiab muaj huab hwm coj. Peb lub xeev ntawm teeb meem yog khoom, kua, thiab roj. Ib qho kev hloov ntawm lub cev muaj xws li hloov dua siab tshiab ntawm ib yam khoom los ntawm ib lub xeev ntawm teeb meem rau lwm tus, tsis hloov nws cov tshuaj muaj pes tsawg leeg.

Yog li ntawd, dab tsi yog ob txoj hauv kev los txheeb xyuas qhov teeb meem?

Ob tus thawj coj txoj kev faib cov teeb meem yog raws li nws lub cev lub cev (raws li roj, kua, los yog khoom) thiab raws li nws muaj pes tsawg leeg (raws li ib yam khoom, compound, los yog sib tov). Ib qho piv txwv ntawm teeb meem tuaj yeem yog roj, kua, lossis khoom. Peb cov no daim ntawv ntawm teeb meem hu ua states teeb meem.

Cov lus teb 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 qhov 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.
