(b) Cov pa roj carbon dioxide yog cov khoom ntshiab uas yog cov khoom sib xyaw (ob lossis ntau dua cov ntsiab lus sib koom ua ke). (c) Txhuas yog cov khoom ntshiab uas yog ib qho khoom (element 13 nyob rau hauv lub sij hawm). (d) Zaub kua zaub yog sib xyaw ua ke ntawm cov kua txiv hmab txiv ntoo, chunks ntawm zaub, thiab rho tawm los ntawm cov zaub.
Tom qab ntawd, ib tug kuj yuav nug, yog kua zaub sib tov los yog tov?
Kua zaub yog a sib tov rau nws tau ua los ntawm nonuniform qhov chaw uas tsis muaj kev lees paub tias ob qhov chaw ua los ntawm cov tebchaw thiab cov khoom. Zaub kua zaub yog hetergenous sib tov vim hais tias ib qho kev sib xyaw ua ke ntawm 2 lossis ntau lub ntsiab lus, xws li dej, (H2O), lossis qabzib, (C6H12O6).
Tsis tas li ntawd, yog cov ntawv sau ua kua zaub sib tov? tsiaj ntawv kua zaub noun [U or S] ( MIXTURE ) Tej zaum lawv yuav muaj cuab kav zoo dua li cov niam txiv feem ntau kom paub txog qhov tsiaj ntawv kua zaub ntawm ESAs, UGMAs, IRAs, thiab lwm yam uas ua rau lub teb chaws txoj kev txuag nyiaj hauv tsev kawm qib siab.
Ua kom pom qhov no, cov kua zaub qaib puas yog cov khoom siv lossis sib xyaw?
Qaib noodles kua zaub yog heterogeneous sib tov . Qhov no yog vim cov noodles nyob sib cais ntawm cov kua. Qee zaum koj tsis tuaj yeem pom qhov sib txawv hauv ib sib tov vim txhua qhov ntawm cov sib tov zoo ib yam li lwm qhov. Cov no sib tov hu ua homogeneous sib tov.
Puas yog pizza yog homogeneous sib xyaw?
Yog li pizza tsis yog qhov sib xyaw. Nws yog ib sib tov Muaj ntau ntau yam xws li khob noom cookie, ntses, nqaij, veggies, cheese, thiab lwm yam. sib tov ntawm lwm yam xws li proteins, starches, qab zib, dej, fiber, vitamins, minerals, thiab lwm yam.
