Question

The resistivity of all pure metals increase with the rise in temperature.

• A. True
• B. False

Answer 1

The correct option is A

True

Resistivity depends on temperature. With the increase in temperature, the random motion of electrons increases. As a 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.
