^{a} Equations
generating the specific volumes, specific isobaric heat capacities,
thermal expansion coefficients and isothermal compressibility
coefficients over a range of temperatures and pressures are
available [399].
[Back]

^{b} Calculated using
the equation *u*^{2} = 1/β_{S}ρ where *u* is the speed of sound (m s^{−1}), β_{S} is the adiabatic compressibility (Pa^{−1})
and ρ is the density (kg m^{−3}).
[Back]

^{c} Calculated using
the equation where T=temperature (K), V=molar volume (m^{3} mol^{−1}), α=thermal expansivity (K^{−1})
and β_{T}=isothermal compressibility
(Pa^{−1}). [Back]

^{d} Calculated using
the equation where α=thermal expansivity (K^{−1}),
T=temperature (K), ρ=density (kg
m^{−3}), and C_{P}=isobaric specific
heat (J kg^{−1} K^{−1}). κ_{S }may also be calculated by β_{S}=β_{T}C_{v} /C_{p}.
[Back]

^{e}
Data is calculated from the supercooled water equation of state [2218].
