Which element increases its electrical conductivity as its temperature increases?
Silicon because it is an intrinsic semiconductor.
How will molar conductivity vary with concentration or temperature?
molar conductivity involves concentration of electrolyte also....but electrolytic conductivity doesn't
Do metals increase electrical conductivity with increasing temperature?
Yes, it does; exactly how it affects the conductivity depends on the metal. As a general rule conductors become LESS conductive as the temperature goes up, while semiconductors become MORE conductive as the temperature goes up.
If an iron rod is heated to a high temperature how would it effect its conductivity?
Generally speaking conductivity of metals decreases as the temperature increases.
When a soluble metallic salt is added to water its electrical conductivity decreases?
No. Its electrical conductivity increases because the positive and negative ions of the salt dissociate in the water.
Which conducts electricity better a hot piece of steel or a cold piece of steel?
The electrical conductivity of a metal generally decreases with increasing temperature. Inversely, the electrical conductivity of a semi-conductor increases with increasing temperature.Source: UK GCSE (high school) science education.
If the electrical conductivity in an electrical circuit decreases then the brightness of the light bulb does what?
Then the brightness of the light buld increases.
What does it mean for a substance to be semiconductor?
A substance as germanium or silicon whose electrical conductivity is intermediate between that of a metal and an insulator; its conductivity increases with temperature and in the presence of impurities. :) Hope that helped;)
Does copper loose electrical conductivities when heated?
no it does not, because it conducts heat and electricityAnswerThe word you are looking for is 'lose', not 'loose'! And the answer is yes. The resistivity of copper increases with temperature, so raising its temperature will cause its resistance to rise or, if you prefer, its conductivity to fall.
Why does dielectric constant decrease with an increase in temperature?
If the temperature increases, the conductivity will increase too which means the dielectric constant is reduced
If the temperature of a metal conductor increases the electrical resistance of the conductor usually?
increases
How does the electrical conductivity of ionic compounds change when they are melted or dissolve in water?
Melting or dissolving ionic compounds increases the electrical conductivity. This is because there are free mobile charged ions that can move in the electric field and conduct current.
