    We are going to use this formula:

    Q = M*C*ΔT

    when Q is the heat released by the material in J

    and M is the mass in gram = 1600 g

    C is the specific heat capacity of iron = 0.4494 J/g

    and ΔT is the changing in temperature = 155 - 25 = 130 °C

    So by substitution:

    ∴ Q = 1600 g * 0.4494 J/g * 130 °C

    = 93475 J

    ∴ The amount of heat released in Joule = 93475 J
