Metallic conductors and semiconductors are heated separately. What are the changes with respect to conductivity?

Which of the following $N$ solutions of $NaCl$ has the maximum specific conductivity?

How does electrolytic conduction differ from metallic conduction?

Assertion: Electrical conductivity of copper increases with increase in temperature.
Reason: The electrical conductivity of metals is due to the motion of electrons.

The limiting molar conductivities $\wedge ^0$ for $NaCl$,$KBr$,and $KCl$ are $126$,$152$,and $150 \ S \ cm^2 \ mol^{-1}$ respectively. The $\wedge ^0$ for $NaBr$ is ............ $S \ cm^2 \ mol^{-1}$.

Write a note on molar conductivity $(\Lambda_{m})$ of a solution.
