1. Cov tshuaj ntshiab tsis tuaj yeem muab cais ua lwm yam teeb meem, thaum a sib tov yog kev sib txuas ntawm ob lossis ntau dua cov khoom ntshiab . 2. A cov khoom ntshiab muaj tas li lub cev thiab tshuaj muaj zog, thaum sib tov muaj qhov sib txawv ntawm lub cev thiab tshuaj lom neeg (piv txwv li, boiling point thiab melting point).

Khaws qhov no rau hauv kev txiav txim siab, puas yog cov khoom ntshiab lossis sib xyaw?

A cov khoom ntshiab yog ib daim ntawv ntawm cov teeb meem uas muaj ib tug tas mus li muaj pes tsawg leeg thiab cov khoom uas tas mus li thoob plaws hauv cov qauv. Cov khoom xyaw yog lub cev sib xyaw ua ke ntawm ob lossis ntau lub ntsiab lus thiab / lossis cov khoom sib txuas. Cov khoom xyaw tuaj yeem muab faib ua homogeneous lossis heterogeneous.

Kuj Paub, dab tsi yog suav tias yog cov khoom ntshiab? Cov cov khoom ntshiab hauv chemistry yog ib lub tswv yim yooj yim heev los tuav. Cov tshuaj ntshiab raug txhais ua tshuaj uas yog tsim los ntawm ib hom atom lossis tsuas yog ib hom molecule (ib pawg ntawm atoms sib koom ua ke). Purity kuj tseem muaj feem cuam tshuam rau cov khoom siv tshuaj lom neeg ntawm a yam khoom.

Hauv qhov no, koj yuav txiav txim siab li cas yog tias ib qho khoom tsis paub yog ib qho ntshiab compound?

Txiav txim seb puas yog ib yam khoom yog tshuaj dawb huv . Yog nws yog dawb huv , cov yam khoom yog ib yam los yog ib compound . Yog ib yam khoom tuaj yeem muab cais ua nws cov ntsiab lus, nws yog a compound . Yog ib yam khoom tsis yog tshuaj lom neeg dawb huv , nws yog ib tug heterogeneous sib tov los yog homogeneous sib tov.

Tus qauv ntshiab yog dab tsi?

Hauv chemistry, a dawb huv cov khoom yog a qauv ntawm qhov teeb meem nrog ob qho tib si meej thiab tas li muaj pes tsawg leeg thiab cov khoom siv tshuaj lom neeg sib txawv. Kom tsis txhob muaj kev ntxhov siab, a dawb huv Cov tshuaj feem ntau hu ua "tshuaj lom neeg."
