Hlau yog cov khoom uas yog cov khoom siv hluav taws xob zoo thiab cua sov. Lawv kuj zoo li ci ntsa iab thiab khoov tau - zoo li tooj liab hlau. Feem ntau ntawm cov ntsiab lus nyob rau hauv lub sij hawm yog cov hlau.
Puas yog cov hlau zoo conductors ntawm hluav taws xob?
Txawm hais tias txhua yam hlau tuaj yeem ua hluav taws xob, qee cov hlau feem ntau siv vim ua kom muaj hluav taws xob ntau. Qhov piv txwv tshaj plaws yog tooj liab. … Thaum Kub muaj qhov ntsuas qhov ntsuas siab, nws ua tau tsawg dua tooj liab.
Vim li cas cov hlau zoo conductors ntawm hluav taws xob?
Metals yog ib qho zoo tshaj plaws conductor ntawm hluav taws xob thiab cua sov vim cov atoms nyob rau hauv cov hlau tsim ib tug matrix los ntawm cov txheej electrons tuaj yeem txav mus los dawb Es tsis txhob orbiting lawv cov atoms, lawv tsim ib lub hiav txwv ntawm electrons uas nyob ib ncig ntawm lub zoo nuclei ntawm interacting hlau ions.
