  1. Question 1

    Q1. The electrical conductivity of a metal decreases with increasing temperature because

    • A) the number of electrons increases
    • B) the number of electrons decreases
    • C) the electron-phonon interaction increases
    • D) the electron-phonon interaction decreases

    Answer: the electron-phonon interaction increases

    Explanation: Increased temperature enhances electron-phonon interaction, reducing conductivity, a concept from the study of electrical conductivity in metals.
