Figure 5
Molecular volumes (left axis) and densities (right axis) of the various ice polymorphs observed during our studies. Solid lines are empirical equations of state of our own derivation for ices II (175 K) and VI (190 K), and of Feistel & Wagner's (2006) for ice Ih (175 K). Dashed lines show the theoretical equation of state from Noya et al. (2007). Dotted lines are the equations of state from Choukroun & Grasset (2007). The two lines marked (i) are the ice III equations of state from Noya et al. (2007) and Choukroun & Grasset (2007) evaluated at 175 and 180 K, respectively. The region covered by the grey box is expanded upon in Fig. 6. |
