    Answer is: 229,5 J of heat is absorbed.

    m (mass of iron - Fe) = 34 g.

    ΔT (change in temperature) = 26°C - 11°C = 15°C.

    cp (specific heat capacity for iron) = 0,450 J/g·°C.

    Q (heat absorbed) = m (Fe) · ΔT · cp.

    Q = 34 g · 15°C · 0,450 J/g·°C.

    Q = 229,5 J = 0,2295 kJ.
