Metals ua hluav taws xob ob qho tib si thaum khov thiab thaum molten. Qhov no yog vim lub delocalised electrons yog mobile. Covalently bonded tshuaj nrog cov qauv molecular yooj yim tsis ua hluav taws xob.
Yuav ua li cas cov hlau ua thaum molten?
Ib yam ntawm cov hlau yog tias lawv tuaj yeem ua hluav taws xob hauv lub xeev khov thiab molten.
Puas yog molten hlau yog tus neeg xyuas pib zoo?
Puas yog molten hlau tseem hluav taws xob conductive? Rau qee qhov yog, tab sis tsis yog tiagRaws li koj siv lub zog (kub) rau ib qho atom, cov electrons dhia mus rau lub plhaub siab dua. Nrog rau sab nraud feem ntau ntawm cov plhaub taum ua kom ruaj khov, cov khoom siv tsis tshua muaj peev xwm lees txais thiab hloov hluav taws xob.
hlau puas muaj hluav taws xob?
Hlau ua hluav taws xob los ntawm tso cai rau cov hluav taws xob dawb txav ntawm cov atoms. … Yog hais tias muaj tsawg zog hloov ntawm atoms, muaj tsawg conductivity. Cov nyiaj ntshiab thiab tooj liab muab qhov zoo tshaj plaws thermal conductivity, nrog aluminium tsawg dua.
Cov hlau puas tsuas yog siv hluav taws xob thaum molten?
Ceeb toom: Cov conductivity ntawm hlau yog vim cov dawb electrons uas tam sim no nyob rau hauv ob lub solid thiab molten lub xeev whereas lub conductivity ntawm lub ionic compound yog vim ions uas tam sim no. nyob rau hauv lub xeev khov tab sis ua dawb xwb nyob rau hauv lub xeev molten.
