    Q1. The Wiedemann-Franz law relates the?

    • A) Thermal conductivity to electrical conductivity
    • B) Specific heat to electrical conductivity
    • C) Thermal conductivity to specific heat
    • D) None of these

    Answer: Thermal conductivity to electrical conductivity

    Explanation: The Wiedemann-Franz law states that K / σ = LT, where K is thermal conductivity, σ is electrical conductivity, and L is the Lorenz number.
