Figure 6
Molecular volumes of ices II and IX, expanded from Fig. 5[link] in order to illustrate the misfits between our observations and empirically derived and theoretically derived equations of state. Note that the open circles representing experiment 1 have been labelled to distinguish ice II (marked with a `2') and ice IX (marked with a `9'). Solid black squares are the ice II data of Fortes et al. (2005BB28) collected in an Al 7075 pressure cell, pressurized under argon gas, along the 225 K isotherm. The solid black line marked `ice II (225 K)' is fitted to the latter data set. The derivation of the other solid lines is described in the text. The dashed lines represent the theoretical equation of state of Noya et al. (2007BB87) evaluated at the indicated temperatures.
