Thaum ob los yog ntau yam khoom sib xyaw ua ke, qhov tshwm sim yog hu ua a sib tov . Cov khoom xyaw tuaj yeem yog cais nyob rau hauv ob pawg loj: homogeneous thiab heterogeneous. Ib homogeneous sib tov yog ib tug nyob rau hauv uas muaj pes tsawg leeg ntawm nws constituents yog uniformly tov thoob plaws.
Kuj nug, 2 hom kev sib tov yog dab tsi?
Muaj ob hom sib tov : (1) Homogenous sib tov . ( 2 ) Heterogeneous sib tov . Ib homogeneous sib tov txhais tau tias "tus sib tov , uas muaj kev sib xyaw ua ke los ntawm nws cov huab hwm coj."
Ib yam li ntawd, ob pab pawg twg tuaj yeem muab faib ua pawg? Cov teeb meem tuaj yeem faib ua ob pawg: cov khoom ntshiab thiab sib tov . Cov khoom ntshiab yog ntxiv rau hauv cov ntsiab lus thiab tshuaj sib xyaw . Cov khoom xyaw yog lub cev sib xyaw ua ke uas tuaj yeem sib cais rau hauv lawv cov khoom qub. Cov tshuaj yog tsim los ntawm ib hom atom los yog molecule.
Tom qab, lo lus nug yog, dab tsi yog hom kev sib tov?
Cov khoom xyaw tuaj yeem muab faib ua peb hom : ncua sib tov , colloidal tshuaj sib tov los yog kev daws teeb meem, raws li lawv ua ke thiab sib cais. Kev ncua sib tov muaj cov ntsiab lus loj dua, colloidal sib tov muaj ntau qhov me me, thiab cov khoom nyob rau hauv ib qho kev daws kom yaj tag rau hauv cov kuab tshuaj.
Koj tuaj yeem faib qhov sib xyaw li cas?
Cov khoom xyaw tuaj yeem yog cais raws li homogeneous los yog heterogeneous. Cov khoom xyaw yog tsim los ntawm cov khoom uas tsis yog tshuaj ua ke. Homogeneous sib tov yog cov kev daws teeb meem. Lub Cheebtsam ntawm cov tshuaj yog sib npaug zos thoob plaws, kom txhua feem ntawm cov tshuaj yog tib yam.

Dab tsi yog lub tswv yim ntawm kev txhawb nqa ntawm kev sib cais ntawm kev sib deev?
Kev txhawb zog yog cov txheej txheem los ntawm kev xaiv ntuj tsim kom muaj kev sib cais ntawm kev sib deev. Kev txhawb zog tuaj yeem tshwm sim raws li hauv qab no: Thaum ob pawg neeg uas tau khaws cia sib nrug, rov qab los rau hauv kev sib cuag, qhov kev sib cais ntawm cov menyuam yaus yuav ua tiav lossis tsis tiav. Yog tias nws ua tiav, speciation tau tshwm sim
Puas yog Oxygen yog cov khoom sib xyaw lossis sib xyaw?
Puas yog oxygen yog ib qho khoom sib xyaw lossis sib xyaw? Oxygen yog ib yam khoom. Nws yog tsim los ntawm tib hom atom, oxygen atoms (8 protons). Nws tshwm sim kom ruaj khov tshaj li molecules ntawm muaj pes tsawg leeg
Puas yog txoj cai ntawm kev sib xyaw ua ke siv tau rau cov khoom sib xyaw?
Cov teeb meem tsis tuaj yeem tsim los yog rhuav tshem, txawm hais tias itis ib qho khoom, qhov sib xyaw, lossis sib xyaw. b) Txoj cai lij choj ntawm qhov tseeb muaj pes tsawg leeg tsuas yog siv rau cov khoom sib txuas nkaus xwb, vim hais tias nws hais txog qhov tsis tu ncua, lossis qhov tseeb, muaj pes tsawg leeg ntawm cov ntsiab lus hauv ib qho chaw
Dab tsi yog qhov sib xyaw ntawm cov khoom sib xyaw?
Ib lub tebchaw muaj cov atom ntawm cov khoom sib txawv ntawm cov tshuaj sib xyaw ua ke hauv qhov sib piv ruaj khov. Kev sib tov yog ib qho kev sib xyaw ntawm ob lossis ntau yam tshuaj uas tsis muaj tshuaj lom neeg ua ke lossis cov tshuaj tiv thaiv. Kev sib xyaw. Cov tshuaj muaj cov ntsiab lus sib txawv hauv qhov sib piv ruaj khov uas tau hais tseg los ntawm cov ntawv cog lus tshuaj
Dab tsi yog txoj cai ntawm kev sib xyaw rau cov khoom sib xyaw?
Rule of Mixtures yog ib txoj hauv kev rau kev kwv yees kwv yees ntawm cov khoom siv sib xyaw, raws li kev xav tias cov khoom sib xyaw yog qhov ntim hnyav nruab nrab ntawm cov theem (matrix thiab dispersed theem) cov khoom
