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 u2 = 1/βSρ where u is the speed of sound (m s−1), βS 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 (m3 mol−1), α=thermal expansivity (K−1), and βT=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 CP=isobaric specific heat (J kg−1 K−1). κS may also be calculated by βS=βTCv /Cp. [Back]
e Data is calculated from the supercooled water equation of state [2089]. [ Back ]
