Iron (Fe) undergoes an allotropic transformation at 912C: upon heating from a BCC (a phase) to an FCC (g phase). Accompanying this transformation is a change in the atomic radius of Fefrom RBCC 0.12584 nm to RFCC 0.12894 nmand, in addition, a change in density (and volume). Compute the percentage volume change associated with this reaction. Does the volume increase or decrease?
