Question
The resistivity of all pure metals increase with the rise in temperature.
Answer: Option A
:
A
Resistivity depends on temperature. Withthe increasein temperature, the random motion of electrons increases. Asa result, the number of collisions of electrons with the positive ions increases. Hence, the resistivity of all pure metals increases with the rise in temperature and decreases with the decrease in temperature.
