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.

Qhov laj thawj twg zoo tshaj plaws piav qhia vim li cas cov hlau tsis muaj ductile es tsis nkig?
Cov hlau yog ductile es tsis txhob nkig vim tias lawv muaj cov ntawv cog lus hloov tau. Ductility txhais tau hais tias muaj peev xwm ntawm cov hlau los kos rau hauv cov xov hlau. Cov hlau muaj cov khoom sib txuas yooj yim. Qhov kev hloov pauv no tso cai rau lawv ua cov khoom siv
Vim li cas lub cube cag ntawm tus lej tsis zoo yog tus lej tsis zoo?
Tus lej tsis zoo lub voos xwmfab hauv paus yuav tsis zoo Txij li qhov ntsuas tus lej txhais tau tias tsa nws mus rau lub zog thib 3 - uas yog khib - lub voos xwmfab ntawm cov lej tsis zoo yuav tsum yog qhov tsis zoo. Thaum lub qhov hluav taws xob tawm (xiav), qhov tshwm sim tsis zoo. Thaum lub qhov hluav taws xob qhib (daj), qhov tshwm sim yog qhov zoo
Vim li cas koj tig lub cim tsis sib xws thaum koj sib npaug lossis faib los ntawm qhov tsis zoo?
Thaum koj muab ob sab los ntawm tus nqi tsis zoo koj ua rau sab uas ntau dua muaj 'loj' tus lej tsis zoo, uas txhais tau tias tam sim no tsawg dua lwm sab! Qhov no yog vim li cas koj yuav tsum tig lub cim thaum twg koj muab los ntawm tus lej tsis zoo
Vim li cas tsis zoo thiab tsis zoo yog qhov zoo?
Thaum koj muab qhov tsis zoo los ntawm qhov tsis zoo koj tau txais qhov zoo, vim tias ob lub cim tsis zoo raug muab tso tseg
Koj yuav ua li cas thiaj paub tias kev sib raug zoo yog qhov zoo lossis tsis zoo?
Qhov zoo correlation coefficient txhais tau hais tias raws li tus nqi ntawm ib qho kev sib txawv nce, tus nqi ntawm lwm qhov sib txawv nce; raws li ib tug txo qhov qis dua. Qhov tsis zoo correlation coefficient qhia tau hais tias raws li ib qho kev sib txawv nce, qhov txo qis, thiab vice-versa
