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
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).
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).
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.
e Data is calculated from the supercooled water equation of state
