How will molar conductivity vary with concentration or temperature?
molar conductivity involves concentration of electrolyte also....but electrolytic conductivity doesn't
Can temperature effect the conductivity of material?
Not sure, in my 9th standard (level of Indian standard education),we studied about conductors....."when temperature increases conductivity of a conductor is also increases". but it is not true in all case because of the properties of the conductors. in some case ...'temperature increase the resistance of a conductor increases so conductivity decreases '. for example: in olden days electronic equipments is more efficient when the atmospheric temperature increases or presence of heat .
What is effect of temperature on conductor?
It depends on the material. In metals, the resistance increases with temperature.
What is the thermal conductivity of a perfect conductor?
The thermal conductivity of a perfect conductor is 1
Why does the resistance of conductor rise with temperature?
as the temperature rises,the drift velocity increases hence relaxation time decreases and resistance increases.
How can you increase the conductivity of a semi conductor?
The conductivity of a semi-conductor can be increased by raising the temperature of the semi-conductor .

If the temperature of a metal conductor increases the electrical resistance of the conductor usually?
increases

HOW DOES conductance vary with temperature?
yes temperature affects the conductivity of conductor and semi conductors but in case of insulators temp. has no effect. While we talk about conductors as temp. increases conductivity decreases ,the question is why, look if we take an example of copper the conductivity is so high at normal temperature because the molecules in the copper are so close but when we increase temperature the inter molecule distance increases and result is increasing resistance of the copper, and as we know that resistance is inversely proportional to the conductivity. So in the case of conductor, temperature affects the conductivity. Hey may be you are familiarize with the new aspect called superconductivity, the same effect is here while the temperature of a conductor is so low approximately -273degree the conductor becomes superconductor because Resistance become so low (can say approx. 0 but not exact 0). You should know that most metals increase their electrical resistivity by about 0.005 per degree. Good luck Rjames007
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.
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;)
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.

The thermal conductivity of a perfect conductor is 1
If pressure is constant and current increases the resistance?
I assume you meant pressure to voltage. The resistance of a conductor is directly proportional to the temperature of the conductor. If the temperature of the conductor increases due to increased current, then the resistance tend to increase too.
Why does the resistance of conductor rise with temperature?
as the temperature rises,the drift velocity increases hence relaxation time decreases and resistance increases.
