    Answer:

    a 52 Joules

    Explanation:

    Specific heat capacity of Au = 0.13 J/g° C

    mass = 4 gram

    initial temperature = 0° C

    final temperature = 100° C

    We are to determine the amount of energy absorbed

    Using the formula:

    Q = mcΔθ

    Q = 4 × (0.13) J/g° C ×(100-0)

    Q = 52 Joules
