Hlau yog cov conductors zoo ( tsis zoo insulators ). Electrons nyob rau hauv txheej txheej ntawm hlau atoms yog dawb txav los ntawm atom mus rau atom. Static charge tsuas yog tsim los ntawm insulators . Cov no yog cov ntaub ntawv uas yuav tsis tso cai rau qhov ntws ntawm cov khoom them (ze li ib txwm electrons) los ntawm lawv.

Tsuas yog li ntawd, vim li cas cov hlau tsis zoo insulators?

Hlau yog cov zoo conductors ntawm ob qho tib si tshav kub thiab hluav taws xob vim hais tias ntawm qhov xwm ntawm metallic bonding uas yog yam ntxwv ntawm hlau . Hlau yog cov conductors zoo (thiab tsis zoo insulators ) vim hais tias lub plhaub sab nrauv electrons tsuas yog xoob khi rau cov ionic cores ntawm lub hlau atoms.

Tsis tas li ntawd, dab tsi yog qhov tsis zoo insulator? Cov ntaub ntawv zoo li iav thiab yas yog pluag hluav taws xob conductors, thiab hu ua insulators . Lawv raug siv los nres hluav taws xob los ntawm qhov chaw uas nws tsis xav tau lossis qhov twg tuaj yeem ua rau muaj kev phom sij, xws li los ntawm peb lub cev. Cov kab hluav taws xob yog cov xov hlau npog hauv cov yas kom peb tuaj yeem tuav lawv yam xyuam xim.

Ib yam li ntawd, nws raug nug, vim li cas hlau yog qhov zoo insulator?

Nyob rau hauv ib tug neeg xyuas pib, hluav taws xob tam sim no tuaj yeem khiav dawb, hauv ib qho rwb thaiv tsev nws ua tsis tau. Hlau xws li tooj liab typify conductors, thaum feem ntau cov khoom tsis yog hlau tau hais tias yog zoo insulators , muaj tsis tshua muaj siab tsis kam mus rau ntws ntawm tus nqi los ntawm lawv. Feem ntau atoms tuav rau lawv cov electrons nruj nreem thiab yog insulators.

Puas yog Hlau yog ib qho zoo insulator ntawm tshav kub?

Hlau feem ntau xav tias txias rau qhov kov. Hlau yog zoo thermal conductors, vim kub hla lawv sai sai. Cov ntaub ntawv no hu ua thermal insulators . Cov thermal no insulators yog zoo rau khaws cia kub tawm thiab hauv.
