tooj liab, nyiaj, txhuas, kub, hlau thiab tooj dag yog cov khoom siv hluav taws xob ntau. Thaum nyiaj thiab kub yog ob qho tib si siv tau, lawv kim heev rau kev siv. Cov khoom ntiag tug ua rau txhua qhov zoo tagnrho rau lub hom phiaj tshwj xeeb.
Cov hlau twg yog qhov zoo tshaj plaws ntawm cov hluav taws xob thiab hluav taws xob?
Silver kuj muaj qhov thermal conductivity siab tshaj plaws ntawm txhua lub caij thiab lub teeb pom kev zoo tshaj plaws. Nyiaj yog qhov zoo tshaj plaws tus neeg xyuas pib vim nws cov electrons muaj kev ywj pheej txav dua li lwm cov ntsiab lus, yog li ua rau nws tsim nyog rau kev siv hluav taws xob thiab hluav taws xob ntau dua li lwm yam khoom.
Yuav ua li cas hlau yog ib tug zoo conductor ntawm hluav taws xob?
Hlau yog tus coj hluav taws xob zoo tshaj plaws?
- Nyiaj. Qhov zoo tshaj plaws tus neeg xyuas pib ntawm hluav taws xob yog cov nyiaj ntshiab, tab sis tsis muaj qhov xav tsis thoob, nws tsis yog ib qho ntawm cov khoom siv feem ntau siv los ua hluav taws xob. …
- Copper. Ib qho ntawm feem ntau siv hlau los ua hluav taws xob yog tooj liab. …
- Aluminium.
Puas yog cov hlau zoo conductors ntawm tshav kub thiab hluav taws xob?
Pom tseeb, txoj hlua yog ib qho insulator, thiab tooj liab yog tus neeg xyuas pib. Raws li txoj cai dav dav, cov khoom uas yog cov khoom siv hluav taws xob zoo ntawm cov cua sov kuj yog cov khoom siv hluav taws xob zoo. Yog li, tag nrho cov hlau yog cov conductors, whereas huab cua, (ntshiab) dej, yas, iav, thiab ceramics yog insulators.
Puas yog tag nrho cov hlau conductors ntawm tshav kub?
Hlau yog suav tias yog cov khoom zoo ntawm cov cua sov whereas cov hlau tsis yog suav tias yog cov khoom tsis zoo ntawm cov cua sov. Ua kom tiav: … Yog li, cov hlau yog cov khoom siv hluav taws xob zoo. Kub, mercury, txhuas thiab alloys tag nrho yog cov zoo conductors ntawm tshav kub.
