Question

Why the conductivity of conductors decrease as temperature
increase​

Answer 1

Answer:

In metals, conductivity is due to movement of free electrons. When temperature increases, the vibration of metal ions increases. This results in increase in resistance of metal and hence, decrease in conductivity.
