Teb: Cov khoom uas tso cua sov dhau los ntawm lawv yooj yim yog hu ua cov khoom hluav taws xob zoo. Cov hlau zoo li tooj liab thiab txhuas muaj qhov thermal conductivity siab tshaj plaws thaum hlau thiab tooj liab muaj qhov qis tshaj. … Kub, Nyiaj, Hlau thiab lwm yam kuj yog ib co piv txwv ntawm zoo thermal conductors tshav kub conductors Fourier txoj cai
Txoj cai ntawm tshav kub conduction, kuj hu ua Fourier txoj cai, hais tias tus nqi ntawm tshav kub hloov los ntawm ib tug cov khoom yog proportional rau qhov tsis zoo gradient nyob rau hauv qhov kub thiab txias rau cheeb tsam, ntawm txoj cai kaum rau qhov gradient, los ntawm cov cua sov ntws. https://en.wikipedia.org › wiki › Thermal_conduction

as well as hluav taws xob conductors.
5 cov khoom siv hluav taws xob zoo 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.
Yuav ua li cas yog ib tug zoo conductor ntawm tshav kub?
Silver yog ib qho zoo tshaj plaws ntawm cov cua sov, thaum stainless hlau yog cov neeg xyuas pib tsis zoo. Qhov tseeb, nyiaj yog ob zaug zoo li tus neeg xyuas pib zoo li txhuas, thiab ze li 10 npaug zoo li tus neeg xyuas pib raws li cov pa roj carbon tsawg. Tooj thiab kub tsuas yog cov hlau uas tuaj ze rau cov nyiaj hauv thermal conductivity.
Cov neeg ua haujlwm zoo yog dab tsi?
Ntau cov hlau yog suav tias yog cov khoom siv hluav taws xob zoo. Tooj liab tsuas yog ib qho ntawm cov khoom siv nrov tshaj plaws uas siv rau cov neeg siv khoom. Lwm cov ntaub ntawv uas qee zaum siv los ua cov khoom siv yog nyiaj, kub, thiab txhuas. … Aluminium thiab lwm yam hlau feem ntau tsis ua hluav taws xob zoo li tooj liab.
Puas yog cov khoom siv hluav taws xob zoo thiab hluav taws xob?
Metals yog cov conductors zoo (ob qho tib si ntawm tshav kub thiab hluav taws xob) vim tsawg kawg yog ib qho hluav taws xob ib atom dawb: piv txwv li, nws tsis khi rau ib qho atom tshwj xeeb, tab sis yog, Hloov chaw, muaj peev xwm txav tau yooj yim thoob plaws hauv cov hlau.

Vim li cas cov khoom siv hluav taws xob hluav taws xob nyob hauv chav sov?
Electrovalent compounds yog tsim los ntawm kev nce lossis poob ntawm electrons ntawm cov khoom. Li no lawv muaj zog intermolecular rog. Li no lawv feem ntau yog khov . Vim li cas ionic compounds solids nyob rau hauv chav tsev kub tab sis covalent compounds zoo li kua los yog gases ntawm chav tsev kub?
Yuav tsum tau hloov cov hluav taws xob hluav taws xob nrog cov hluav taws xob?
Kuv puas yuav tsum hloov cov hluav taws xob hluav taws xob nrog cov hluav taws xob? Ignition coils thiab spark plugs ua haujlwm zoo ua ke. … Tab sis yog tias koj tsuas yog hloov koj lub qhov hluav taws xob ua ib feem ntawm kev saib xyuas niaj hnub, nws tsis tsim nyog los hloov koj cov hluav taws xob hluav taws xob tib lub sijhawm tshwj tsis yog muaj cov cim qhia tias lawv ua tsis tau Yuav tsum hloov cov hluav taws xob hluav taws xob ntau npaum li cas?
Puas yog roj hluav taws xob hluav taws xob hluav taws xob zoo?
Central gas heating systems siv natural gas rau tsev sov. Kuv xav siv cov pa roj carbon monoxide tsis zoo rau lub hauv nruab nrab cua sov vim tias nws yooj yim, yooj yim, txhim khu kev qha, thiab ua haujlwm zoo dua. Thaum tshav kub kub uas los ntawm cov nkev ntuj pom tau tias sov dua li cua sov tawm ntawm lub hauv paus system .
Puas yog cov tshuab hluav taws xob sab hauv hluav taws xob zoo?
Feem ntau cov tshuab hluav taws xob sab hauv yog qhov ua tsis tau zoo ntawm kev tig cov roj hlawv rau hauv lub zog siv tau. Qhov kev ua tau zoo uas lawv ua tau yog ntsuas nyob rau hauv cov nqe lus ntawm " thermal efficiency ", thiab feem ntau cov roj av combustion xyaw nruab nrab nyob ib ncig ntawm 20 feem pua thermal efficiency .
Cov hlau twg yog cov khoom siv hluav taws xob zoo thiab hluav taws xob?
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 .
