    530 J

    Explanation:

    Heat absorbed is:

    q = mCΔT

    where m is mass, C is the specific heat, and ΔT is the temperature increase.

    The specific heat of iron is 0.449 J/g/C. Therefore:

    q = (62 g) (0.449 J/g/C) (27°C - 8°C)

    q ≈ 529 J

    Rounded to two significant figures, the heat absorbed is approximately 530 J.
