First you need the specific heat of Iron ( .45 kJ/kg K).
Next I will have to assume that 9.56×104Joules is actually 9.56 × 10^4 Joules = 95.6kJ
95.6 kJ ÷ 20kg ÷.45kJ/kg K = 10.62 K
Next you need Iron's coefficient of thermal expansion: .0000118/K
59.6 × .0000118 × 10.62 = .00747 cm (increase in length).
