  1. Question 1

    Q1. The Debye temperature of a crystal is 300 K. What is the specific heat at 100 K?

    • A) 1.2 J/molK
    • B) 2.4 J/molK
    • C) 0.6 J/molK
    • D) 3 J/molK

    Answer: 2.4 J/molK

    Explanation: Using the Debye model, C_v = (12/5) * π⁴ * N * k * (T/θ_D)³ for T << θ_D.
