    The effect of temperature increase on conduction is as follows

    A)  metallic conduction increases, electrolytic conduction decreases

    B)  electrolytic conduction increases, metallic conduction decreases

    C)  both metallic and electrolytic conduction decrease

    D)  both metallic and electrolytic conduction increase

    Correct Answer: B

    Solution :

                    With increase in temperature, electrolytic conduction increases because dissociation increases but metallic conduction decreases because kernels start vibrating and hinder the flow of electrons.
