Answer: 
Explanation:
Given
Mass of iron piece is 
Heat absorbed 
Temperature changes from 
i.e.
Heat absorbed is given by ![Q=mc\Delta T\quad [c=\text{specific heat of material}]](https://tex.z-dn.net/?f=Q%3Dmc%5CDelta%20T%5Cquad%20%5Bc%3D%5Ctext%7Bspecific%20heat%20of%20material%7D%5D)
Insert the values
Thus, the specific heat of iron is
