The electrical conductivity of metal sometimes decreases with the?
Correct answer: B. Increase in temperature
- A. Increase in pressure
- B. Increase in temperature
- C. Decrease in temperature
- D. Decrease in pressure
Explanation
The electrical conductivity of metals decreases with an increase in temperature as with the increase in temperature, the positive metal ions also begin to oscillate and the motion hinders the free movement of mobile electrons between the positive ions.This hindrance decreases the electrical conductivity.
