Muaj plaub yam cuam tshuam tsis kam uas yog Temperature, Length of wire, Area of the cross-section of wire and nature of the material. Thaum muaj tam sim no hauv cov khoom siv hluav taws xob, cov hluav taws xob dawb txav los ntawm cov khoom siv thiab qee zaus tsoo nrog atoms.
Ua raws li qhov no, dab tsi yog 4 yam uas cuam tshuam rau kev tiv thaiv?
Muaj 4 yam sib txawv uas cuam tshuam rau kev tiv thaiv:
- Hom ntawm cov khoom uas tus resistor yog ua.
- Qhov ntev ntawm tus resistor.
- Lub thickness ntawm resistor.
- Qhov kub ntawm tus neeg xyuas pib.
Tsis tas li ntawd, dab tsi yog qhov tseem ceeb ntawm kev tiv thaiv? Cov yam ntxwv uas cuam tshuam rau Resistance Ntau npaum li cas cov khoom muaj nyob ntawm ntau yam: hom khoom, nws qhov dav, nws ntev , thiab nws kub . Txhua cov ntaub ntawv muaj qee qhov kev tiv thaiv, tab sis qee cov ntaub ntawv tiv thaiv qhov ntws ntawm hluav taws xob tam sim no ntau dua lossis tsawg dua li lwm cov ntaub ntawv ua.
Yog li ntawd, dab tsi yog 3 yam uas cuam tshuam rau kev tiv thaiv?
Muaj ob peb yam uas cuam tshuam rau qhov tsis kam ntawm tus neeg xyuas pib;
- cov khoom siv, xws li tooj liab, muaj kev tiv thaiv qis dua li cov hlau.
- ntev - ntev ntawm cov xov hlau muaj kev tiv thaiv ntau dua.
- thickness - me me txoj kab uas hla hlau muaj ntau dua kuj.
- kub - cua sov ib tug hlau tsub kom nws kuj.
Dab tsi yog qhov cuam tshuam rau qhov tsis kam ntawm ib qho hluav taws xob conductor?
Muaj plaub yam uas cuam tshuam qhov tsis kam ntawm tus neeg xyuas pib. Thickness (cross sectional cheeb tsam ntawm cov hlau), ntev, thiab kub . Qhov thib plaub yog qhov conductivity ntawm cov khoom siv. Qee cov hlau (tooj liab, nyiaj) tsuas yog siv hluav taws xob ntau dua li lwm tus (hlau, txhuas).

Dab tsi yog cov khoom lag luam hauv kev sib npaug molecular rau kev ua tiav cov tshuaj tiv thaiv ntawm aqueous barium hydroxide thiab nitric acid?
Ba(OH)2 + 2HNO3 → Ba(NO3)2 + 2H2O. Barium hydroxide react nrog nitric acid los tsim barium nitrate thiab dej
Dab tsi yog kev sib tsoo txoj kev xav ntawm cov tshuaj tiv thaiv?
Kev sib tsoo txoj kev xav, txoj kev xav tau siv los kwv yees tus nqi ntawm cov tshuaj tiv thaiv, tshwj xeeb tshaj yog rau cov pa roj. Kev sib tsoo txoj kev xav yog nyob ntawm qhov kev xav tias qhov kev tshwm sim tshwm sim yog tsim nyog rau cov hom reacting (atoms lossis molecules) tuaj ua ke lossis sib tsoo nrog ib leeg
Vim li cas cov tshuaj tiv thaiv kev zom zaub mov hu ua hydrolysis cov tshuaj tiv thaiv?
Thaum lub sij hawm zom mov, piv txwv li, decompositionreactions zom cov zaub mov loj rau hauv cov me me los ntawm kev ntxiv cov dej molecules. Hom tshuaj no hu ua hydrolysis. Raws li dej absorbs heatenergy, qee lub zog yog siv los rhuav tshem hydrogenbonds
Cov tshuaj tiv thaiv dab tsi yog qhov tshuaj tiv thaiv neutralization?
Neutralization yog ib hom tshuaj tiv thaiv nyob rau hauv uas muaj zog acid thiab muaj zog puag react nrog ib leeg los tsim dej thiab ntsev
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
