Muaj ob qhov kev faib tawm tseem ceeb ntawm cov zaub mov. Cov zaub mov tseem ceeb yog cov zaub mov uas koj lub cev xav tau nyob rau hauv qhov loj (lossis loj) ntau, thiab cov pob zeb hauv av yog cov zaub mov uas koj lub cev xav tau hauv qhov me me (lossis kab) ntau. Cov zaub mov tseem ceeb muaj xws li sodium, potassium, chloride, calcium phosphorus, magnesium thiab leej faj.
Yog li ntawd, dab tsi yog cov ntxhia kev faib tawm?
Lub Dana system faib cov ntxhia mus rau yim chav kawm yooj yim. Cov chav kawm yog: haiv neeg, silicates, oxides, sulfides, sulfates, halides, carbonates, phosphates, thiab mineraloids. Daim duab hauv qab no muaj cov duab thiab cov lus piav qhia ntawm txhua chav kawm nrog qhov txuas mus rau cov piv txwv thiab cov ntsiab lus ntxiv.
Tsis tas li ntawd, dab tsi yog qhov sib txawv ntawm cov zaub mov thiab lawv siv? 40 hom minerals & lawv siv
- Antimony. Antimony yog cov hlau uas siv nrog rau cov hlau los tsim cov roj teeb rau khaws cov phiaj xwm hluav taws xob.
- Asbestos. Asbestos muaj lub koob npe nrov tsis txaus ntseeg ua rau mob qog noj ntshav hauv cov neeg ua haujlwm nyob ib puag ncig nws.
- Barium.
- Columbite-tantalite.
- Tooj.
- Feldspar.
- Gypsum.
- Halite.
Ib yam li ntawd, nws yog nug, dab tsi yog mineral cais nws nrog piv txwv?
cov ntxhia ua tau cais raws li lawv cov tshuaj muaj pes tsawg leeg. Raws li cov tswv yim no, lawv tau muab faib ua cov chav kawm raws li lawv qhov tseem ceeb anion lossis anionic pawg ( e.g ., halides, oxides, thiab sulfides). Cov ntxhia yog homogeneous ib txwm tshwm sim yam khoom uas muaj cov qauv tsim sab hauv.
Koj tuaj yeem txheeb xyuas cov ntxhia li cas?
Zaj Lus Qhia
- Koj tuaj yeem txheeb xyuas cov ntxhia los ntawm nws cov tsos thiab lwm yam khoom.
- Cov xim thiab luster piav txog cov tsos ntawm cov ntxhia, thiab streak piav txog cov xim ntawm cov hmoov ntxhia.
- Txhua pob zeb muaj ib tug yam ntxwv ceev.
- Mohs Hardness Scale yog siv los sib piv cov hardness ntawm cov zaub mov.

Dab tsi yog qhov tseem ceeb ntawm kev siv cov zaub mov?
Kev siv cov zaub mov. Cov ntxhia zoo li tooj liab yog siv hauv cov khoom siv hluav taws xob vim nws yog cov khoom siv hluav taws xob zoo. Av nplaum yog siv los ua cov cement thiab lwm yam uas pab tsim txoj kev. Fiberglass, tshuaj ntxuav yog tsim los ntawm borax
Cov khoom siv tshuaj lom neeg ntawm cov zaub mov yog dab tsi?
Cov khoom uas pab geologists txheeb xyuas cov pob zeb hauv pob zeb yog: xim, hardness, luster, crystal forms, ntom, thiab cleavage. Crystal form, cleavage, thiab hardness yog txiav txim siab feem ntau los ntawm cov qauv siv lead ua ntawm qib atomic. Xim thiab ntom yog txiav txim siab feem ntau los ntawm cov tshuaj muaj pes tsawg leeg
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Dab tsi yog qhov txawv ntawm lub cev thiab tshuaj lom neeg ntawm cov zaub mov?
Minerals raug cais raws li lawv cov tshuaj muaj pes tsawg leeg, uas tau qhia hauv lawv lub cev. Cov qauv no, qhov thib ob hauv cov kab hauv cov ntxhia, piav qhia txog lub cev lub zog uas feem ntau siv los txheeb xyuas cov zaub mov. Cov no muaj xws li xim, crystal form, hardness, ntom, luster, thiab cleavage
Cov tshuaj dab tsi tuaj yeem txav mus rau hauv lossis tawm ntawm cov hlwb los ntawm kev nthuav tawm?
Dej, carbon dioxide, thiab oxygen yog ib qho ntawm ob peb yam yooj yim molecules uas muaj peev xwm hla lub cell membrane los ntawm diffusion (los yog ib hom diffusion hu ua osmosis). Diffusion yog ib txoj hauv kev ntawm kev txav ntawm cov khoom nyob rau hauv cov hlwb, nrog rau txoj kev rau cov me me molecules tseem ceeb hla lub cell membrane
