Iron undergoes a polymorphic transformation at 912°C. At a temperature just below 912°C it has a BCC structure (a = 0.293 nm), and at a temperature just above 912°C the structure is FCC (a = 0.363 nm). Upon heating a block of iron past 912°C, does the volume increase or decrease, and by what percent?
