Vim nws qhov ua tau zoo raws li tus neeg xyuas hluav taws xob, cadmium feem ntau siv hauv electroplating thiab hauv roj teeb. Tsis tas li ntawd, cadmium thiab cov kev daws teeb meem ntawm nws cov tebchaw yog tshuaj lom thiab yuav tsum tau ua tib zoo saib xyuas.
Puas cadmium yog ib qho zoo conductor ntawm tshav kub thiab hluav taws xob?
Cadmium yog ib qho muag muag, malleable, ductile, xiav-dawb hlau, uas yooj yim txiav nrog riam. Nws yog ib qhocov khoom siv hluav taws xob zoo heev thiab qhia tau zoo tiv thaiv corrosion thiab tawm tsam los ntawm cov tshuaj. Nws zoo ib yam li zinc hauv nws cov khoom siv tshuaj.
Puas cadmium yog hlau lossis nonmetal?
Cadmium (Cd) yog soft, malleable, bluish dawb hlaupom nyob rau hauv zinc ores, thiab rau ib tug ntau tsawg npaum li cas, nyob rau hauv lub cadmium mineral greenockite. Feem ntau ntawm cov cadmium tsim hnub no yog tau los ntawm zinc byproducts thiab rov qab los ntawm siv nickel-cadmium roj teeb.
Cadmium yog dab tsi?
Cadmium yog lustrous, silver-white, ductile, malleable hlau. Nws qhov chaw muaj xim xiav thiab cov hlau yog mos txaus los txiav nrog rab riam, tab sis nws tarnishes hauv huab cua. Nws yog soluble hauv acids tab sis tsis nyob rau hauv alkalis. Nws zoo sib xws rau ntau yam ntawm zinc tab sis nws tsim ntau cov tebchaw.
Puas yog cadmium magnetic?
Lub magnetic susceptibilities ntawm cadmium manganites, (Cd x2+Mn1 -+)Mn2 3+O4,tau ntsuas ntawm 4 · 2 ° K thiab 1000 ° K ua haujlwm ntawm thaj chaw thiab qhov kub thiab txias. Tag nrho cov qauv tshwj tsis yog x=1 ua ferrimagnetic ntawm qhov kub thiab txias thiab qhia peb qhov kev hloov pauv.

Dab tsi yog qhov txawv ntawm lub tshuab hluav taws xob thiab lub tshuab hluav taws xob?
Gramophone: Txhua lub suab kaw suab, lossis cov cuab yeej ua si yav dhau los-cov suab kaw, tshwj xeeb tshaj yog tias nws siv lub tiaj tiaj tiaj. Phonograph: Txhua lub suab kaw suab, lossis cov cuab yeej siv rau kev ua si cov suab uas tau kaw dhau los, tshwj xeeb tshaj yog tias nws siv lub tog raj kheej tig.
Puas siv hluav taws xob hauv qhov hluav taws xob tuaj yeem siv rau ntawm qhov loj?
Txawm hais tias tsawg dua, lwm hom kev siv hluav taws xob hauv av tuaj yeem siv los muab ntau lub zog ntau dua. Tapping qhov chaw ntawm cov dej kub faus rau hauv qab lub ntiaj teb saum npoo tuaj yeem muab cua sov rau cov neeg coob coob, thiab tsim kom muaj zog txaus los tsim hluav taws xob loj.
Puas yog cov hluav taws xob muaj hluav taws xob zoo?
Ntau yam tseem ceeb, lossis subatomic, cov khoom ntawm cov khoom muaj cov khoom siv hluav taws xob. Piv txwv li, electrons muaj tus nqi tsis zoothiab protons muaj tus nqi zoo, tab sis neutrons muaj pes tsawg tus nqi. Yuav ua li cas them electrons e nqa?
Puas hluav taws xob hluav taws xob puas tsim hluav taws xob?
Coal feem ntau siv roj los tsim hluav taws xobhauv Tebchaws Meskas. Hauv cov chaw tsim hluav taws xob hluav taws xob hluav taws xob, cov hluav taws xob bituminous, subbituminous thee, lossis lignite raug hlawv. Cov cua kub uas tsim los ntawm kev sib xyaw ntawm cov thee yog siv los hloov cov dej mus rau hauv qhov chaw siab zog, uas tsav lub turbine, uas tsim hluav taws xob.
Lub tshuab hluav taws xob hluav taws xob tsim hluav taws xob li cas?
Piav seb lub twj hluav taws xob hluav taws xob tsim hluav taws xob hla lub membrane li cas. Los ntawm pum electrons hla lub membrane, sab uas cov electrons raug tshem tawm muaj qhov zoo dua, thaum sab tau txais cov hluav taws xob ntau muaj qhov tsis zoo.
