Kev mob hnyav khoom , xws li ceev thiab xim, tsis nyob ntawm tus tus nqi ntawm tus khoom tam sim no. Lub cev muaj peev xwm ntsuas yam tsis hloov cov khoom tshuaj tus kheej. Tshuaj muaj peev xwm ntsuas tsuas yog hloov ib yam khoom tshuaj tus kheej.
Ntawm no, dab tsi yog lub cev thiab tshuaj lom neeg cov khoom ntawm cov khoom?
General khoom ntawm teeb meem xws li xim , ntom, hardness, yog piv txwv ntawm lub cev muaj zog. Cov khoom uas piav qhia txog yuav ua li cas cov khoom hloov pauv mus rau hauv cov khoom sib txawv kiag li hu ua chemical properties. Flammability thiab corrosion / oxidation kuj yog piv txwv ntawm chemical zog.
Tsis tas li ntawd, cov khoom siv tshuaj lom neeg yog dab tsi? A chemical khoom yog ib tug yam ntxwv ntawm ib yam khoom uas yuav raug soj ntsuam thaum nws koom nyob rau hauv a tshuaj tshuaj tiv thaiv. Piv txwv ntawm tshuaj muaj zog suav nrog flammability, toxicity, tshuaj stability, thiab kub ntawm combustion.
Yog li ntawd, yuav siv lub cev lub cev li cas los txheeb xyuas cov khoom?
A khoom ntiag tug yog ib tug yam ntxwv ntawm a yam khoom uas ua tau raug soj ntsuam los yog ntsuas yam tsis hloov tus kheej ntawm tus yam khoom . Lub cev muaj zog muaj xws li xim, ntom, hardness, thiab melting thiab boiling ntsiab lus. A chemical khoom piav txog lub peev xwm ntawm a yam khoom mus undergo ib qho tshwj xeeb tshuaj hloov.
Dab tsi yog qhov txawv ntawm lub cev thiab cov khoom siv tshuaj lom neeg muab piv txwv ntawm txhua tus?
Cov khoom siv tshuaj tsuas yog pom thaum lub sijhawm a tshuaj cov tshuaj tiv thaiv thiab yog li hloov cov tshuaj tshuaj muaj pes tsawg leeg. Tej zaum qhov zoo tshaj plaws rau paub qhov txawv ntawm ob yog los ntawm piv txwv . Piv txwv ntawm lub cev muaj zog yuav muaj xws li khov, melting, thiab boiling point, ceev, loj, thiab ntim.

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
Dab tsi yog cov yam ntxwv ntawm lub cev thiab tshuaj lom neeg ntawm dej?
Cov tshuaj lom neeg thiab lub cev tseem ceeb ntawm cov dej yog: dej tsis qab, tsis muaj ntxhiab tsw ntawm tus qauv kub thiab siab. Cov xim ntawm cov dej thiab dej khov yog, intrinsically, ib tug me ntsis xiav hue, txawm tias dej zoo li tsis muaj xim nyob rau hauv me me
Puas yog PH yog cov khoom siv tshuaj lom neeg lossis lub cev?
Cov cuab yeej tshuaj yog ib yam ntxwv uas tsuas yog ntsuas tau los ntawm kev hloov cov khoom siv tshuaj lom neeg. Cov cuab yeej tshuaj tsis tuaj yeem tsim los ntawm kev kov lossis saib cov khoom. Yuav tsum muaj tshuaj hloov pauv kom pom nws! Qee qhov piv txwv yog: flammability, pH, thiab reactivity nrog dej los yog acid
Dab tsi yog qhov sib txawv tseem ceeb ntawm tshuaj lom neeg thiab cov tshuaj tiv thaiv nuclear Lub hlwb?
(1) Cov tshuaj tiv thaiv Nuclear cuam tshuam nrog kev hloov pauv ntawm inan atom lub nucleus, feem ntau tsim cov khoom sib txawv, nrog rau kev tawm ntawm cov hluav taws xob xws liα, β thiab gamma; lwm ray. Cov tshuaj tiv thaiv tshuaj, ntawm qhov tod tes, tsuas yog muaj kev hloov pauv ntawm cov hluav taws xob thiab tsis cuam tshuam nrog kev hloov pauv hauv cov nuclei
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
