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 tshav kub?

Ntxiv nrog rau kev ua hluav taws xob, ntau cov hlau muaj ob peb lwm cov khoom sib koom, suav nrog: Cov hlau muaj cov ntsiab lus melting siab. Qhov no piav qhia vim li cas txhua cov hlau, tshwj tsis yog cov mercury, yog cov khib nyiab ntawm chav tsev kub. Cov hlau feem ntau yog cov khoom siv hluav taws xob zoo.

Vim li cas cov hlau zoo conductors ntawm tshav kub?

Peb paub, cua sov yog ua los ntawm ib qho kawg mus rau lwm qhov thaum cov khoom ntawm cov khoom vibrate. Vim qhov kev vibration no, lub zog kinetic tau dhau los ntawm ib qho mus rau lwm qhov. Hauv cov hlau, muaj cov hluav taws xob dawb uas ua rau lub zog hloov tau yooj yim Yog li, cov hlau yog cov khoom zoo ntawm cov cua sov.

Puas yog hlau tsis zoo conductors ntawm tshav kub?

Hlau thiab pob zeb yog suav tias yog cov neeg ua haujlwm zoo vim tias lawv tuaj yeem hloov pauv sai sai, thaum cov ntaub ntawv xws li ntoo, ntawv, cua, thiab ntaub yog cov khoom siv hluav taws xob tsis zoo. … Cov khoom uas tsis zoo conductors ntawm tshav kub yog hu ua insulatorsCua, uas muaj ib tug conduction coefficient ntawm.

Yuav ua li cas hlau yog cov neeg pluag tshaj plaws ntawm tshav kub?

Cov lus teb yog Lead. Ntawm cov hlau: Copper & Zinc yog cov conductors zoo. Mercury hlau yog ib tug tsis zoo conductor thaum Lead yog cov neeg pluag tshaj plaws.
