Query: Equation of state for supercooled water at pressures up to 400 MPa   An equation of state is presented for the thermodynamic properties of cold
and supercooled water. It is valid for temperatures from the homogeneous ice
nucleation temperature up to 300 K and for pressures up to 400 MPa, and can be
extrapolated up to 1000 MPa. The equation of state is compared with
experimental data for the density, expansion coefficient, isothermal
compressibility, speed of sound, and heat capacity. Estimates for the accuracy
of the equation are given. The melting curve of ice I is calculated from the
phase-equilibrium condition between the proposed equation and an existing
equation of state for ice I.
