Pure iron is heated to above the phase transition temperature, where it changes from BCC structure to FCC crystal structure, at 910 C. Given that the packing factor of BCC lattice = 0.68 and the packing factor of FCC lattice = 0.74. Determine percentage volume change that occurs from the BCC to FCC transition.
