Khoom: Kub; tooj liab; Potassium; Sodium; Nyiaj
Tib neeg kuj nug, dab tsi yog qhov zoo tshaj plaws conductor ntawm hluav taws xob thiab cua sov?
❖ Nyiaj yog tus neeg xyuas pib zoo tshaj plaws ntawm ob qho tib si kub thiab hluav taws xob ntawm cov hlau nrog tus nqi thermal conduction txog li 430 W / (mK). ❖ Kub & tooj liab ob leeg tuaj sib fwm nyob ze nyiaj . ❖ Nyiaj kuj muaj lub siab tshaj plaws thermal conductivity ntawm tej yam & lub siab tshaj plaws lub teeb reflectance.
Ib sab saum toj, cov hlau twg yog tus neeg xyuas pib ntawm hluav taws xob thiab cua sov? Hauv qhov no, hlau, zoo tus thawj coj ntawm kub thiab hluav taws xob . Yuav ua li cas cov ntaub ntawv muaj peev xwm ua tau hluav taws xob thiab cua sov yog vim cov dawb electrons tam sim no nyob rau hauv cov khoom. Hauv hlau, nws yog xim hlau kev sib raug zoo yog tam sim no.
Kuj paub, zinc puas yog ib qho zoo conductor ntawm tshav kub thiab hluav taws xob?
Hauv chav sov, zinc yog nkig, tab sis nws dhau los ua malleable ntawm 100 C. Malleable txhais tau tias nws tuaj yeem khoov thiab zoo li yam tsis muaj kev tawg. Zinc yog ib nrab tus neeg xyuas pib zoo ntawm hluav taws xob . Lub cev siv zinc ua cov khoom noj thiab cov khoom noj.
Puas yog kev hloov pauv hlau zoo conductors ntawm tshav kub thiab hluav taws xob?
Hloov cov hlau yog superior conductors ntawm tshav kub zoo li hluav taws xob . Lawv yog cov malleable, uas txhais tau hais tias lawv tuaj yeem ua rau hauv cov nplooj ntawv, thiab ductile, uas txhais tau tias lawv tuaj yeem ua rau hauv cov xov hlau. Qee cov khoom ntawm kev hloov hlau muab lawv sib nrug ntawm lwm tus hlau.

Lub ntsiab txhais ntawm lo lus hluav taws xob hluav taws xob yog dab tsi?
Npe. Cov hluav taws xob hluav taws xob txhais tau tias yog hluav taws xob hluav taws xob uas tso cai rau kev ua haujlwm kom tiav. Ib qho piv txwv ntawm lub zog hluav taws xob yog lub zog los ntawm lub qhov hluav taws xob ntsaws. YourDictionary txhais thiab siv piv txwv
Dab tsi yog qhov txawv ntawm kev txuag hluav taws xob thiab lub hauv paus ntsiab lus ntawm kev txuag hluav taws xob?
Lub caloric txoj kev xav tau khaws cia tias cov cua sov tsis tuaj yeem tsim los yog rhuav tshem, qhov kev txuag ntawm lub zog ua rau lub hauv paus ntsiab lus tsis sib xws uas cov cua sov thiab cov tshuab ua haujlwm sib hloov tau
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
