    Silicon and copper are cooled to a temperature of 300K, then resistivity:

    A)  for Cu increases and for Si decreases

    B)  for Si increases and for Cu decreases

    C)  decreases for both Si and Cu           

    D)  increases for both Si and Cu

    Correct Answer: B

    Solution :

                    Copper is a conductor whereas silicon is a semiconductor. Thus, resistivity of silicon increases when cooled and that of copper decreases when cooled.
