Iron (fe) undergoes an allotropic transformation at 912°c: upon heating from a bcc (α phase) to an fcc (γ phase). accompanying this transformation is a change in the atomic radius of fe—from rbcc = 0.12584 nm to rfcc = 0.12894 nm—and, in addition, a change in density (and volume). compute the percentage volume change associated with this reaction. indicate a decreasing volume by a negative number.
