Gadolinium metal undergoes a polymorphic phase transformation from HCP to BCC upon heating at 1260oC. The lattice parameters for the HCP phase are a=0.3745 nm and c=1.18525 nm. The lattice parameter for the BCC phase is 0.4060 nm. Calculate the density of each phase and the percent change in volume associated with this transformation.
