A piece of copper and other of germanium are cooled from the room temperature to 80 K, then

Question 1

(a) resistance of each will increase

(b) resistance of copper will decrease

(c) the resistance of copper will increase while that of germanium will decrease

(d) the resistance of copper will decrease while that of germanium will increase

Question 2

The correct option is (d) the resistance of copper will decrease while that of germanium will increase.

Explanation:

Copper is a conductor so its resistance decreases on decreasing temperature as thermal agitation decreases whereas germanium is semiconductor which on decreasing temperature resistance increases.
