Electrical conductance through metals is called electronic conductance and it ______.

Options

A. decreases with increase in temperature
B. increases with increase in temperature
C. decreases with decrease in temperature
D. does not depend on temperature

Answer

A

Explanation

Metals are good conductors due to the presence of free electrons and when we increase the temperature the metal ions start vibrating which lead to the increase in resistance so the conductivity is decreased. So conductivity decreases with the increase in temperature..
