    The resistance of a metal increases with increasing temperature because

    A)   the collisions of the conducting electrons with the electrons increase

    B)   the collisions of the conducting electrons with the lattice consisting of the ions of the metal increase

    C)   the number of conduction electrons decrease

    D)   the number of conduction electrons increase  

    Correct Answer: B

    Solution :

    The resistance of a metal increases with increasing temperature this is because, with increase in temperature the ions of the conductor vibrate with greater amplitude and the collision between ions and electrons becomes more frequent.
