Vim li cas cov hlau ua kom sov zoo? Cov electrons nyob rau hauv cov hlau yog delocalised electrons thiab yog dawb txav electrons yog li thaum lawv nce lub zog (kub) lawv vibrate sai duathiab txav mus los, qhov no txhais tau tias lawv tuaj yeem hla lub zog sai dua..
Vim li cas cov hluav taws xob ua kom sov?
Raws li cov hluav taws xob txav mus los ntawm tus neeg xyuas pib hlau, qee qhov sib tsoo nrog atoms, lwm yam hluav taws xob lossis impurities. Cov kev sib tsoo no ua rau muaj kev tiv thaiv thiab ua kom sov. Cua sov cov hlau conductor ua rau atoms kom vibrate ntau, uas ua rau nws nyuaj rau cov electrons ntws, ua rau muaj zog.
Huab cua sov ua li cas?
Kub tuaj yeem taug kev los ntawm ib qho mus rau lwm qhov hauv peb txoj kev: Conduction, Convection thiab Radiation … Hlau yog ib tug zoo conduction ntawm tshav kub. Kev coj ua tshwm sim thaum ib yam khoom raug cua sov, cov khoom yuav tau txais lub zog ntau dua, thiab vibrate ntau dua. Cov molecules tom qab ntawd tsoo rau hauv cov khoom nyob ze thiab hloov qee lub zog rau lawv.
Kev ua kom sov yog dab tsi?
Kub conduction (los yog thermal conduction) yog txav ntawm tshav kub ntawm ib yam khoom mus rau lwm qhov uas muaj qhov kub thiab txias thaum lawv kov ib leegPiv txwv li, peb tuaj yeem sov peb. txhais tes los ntawm kev kov cov fwj dej kub. … Lwm txoj hauv kev los hloov cov cua sov yog los ntawm thermal tawg thiab/los yog convection.
5 qhov hluav taws xob zoo hluav taws xob yog dab tsi?
Qee cov ntaub ntawv tso cai rau cov cua sov ntws los ntawm lawv thiab lawv paub tias yog cov khoom siv hluav taws xob zoo los yog cov khoom siv hluav taws xob xws li hlau, txhuas, tooj liab, nyiaj, tooj dag, txhuas thiab stainless.
