Cov dej ntxhia muaj ions, zoo li sodium ion thiab lwm yam, yog li nws tuaj yeem ua tam sim no. Cov dej ntshiab xws li dej distilled tsis muaj ion, yog li nws tsis ua tam sim no.
Cov pob zeb puas ua hluav taws xob?
Ntaus thiab ores tuaj yeem hla hluav taws xob yog tias lawv yog cov neeg ua haujlwm. Qee qhov yog semi-conductors, uas dhau hluav taws xob tsuas yog nrog cov xwm txheej zoo. Feem ntau cov minerals thiab ores yog insulators-lawv tsis pub hluav taws xob hla lawv.
Cov dej ntshiab puas tuaj yeem ua hluav taws xob?
Zoo tiag tiag, dej ntshiab yog ib qho zoo insulator thiab tsis ua hluav taws xob.
hom dej twg ua hluav taws xob?
Cov dej ntshiab muaj cov ions tsawg heev thiab yog li nws yog qhov hluav taws xob tsis zoo. Tab sis thaum impuritiesxws li ntsev lossis qab zib yaj hauv dej, cov tshuaj ua kom hluav taws xob zoo heev.
Puas yog cov ntxhia ua tus coj zoo?
Tsuas ib qho me me ntawm cov ntxhia yog cov neeg ua haujlwm zoo; Lawv yog cov khoom siv hlau thiab cov ntxhia graphite. Cov conductors no tuaj yeem muab tso rau ntawm cov xaim nqa hluav taws xob, thiab hluav taws xob yuav dhau mus.
