Footnotes

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 CP=CV+temperature*molar volume*expansivity^2/compressibility where T=temperature (K), V=molar volume (m3 mol-1), α=thermal expansivity (K-1) and κT=isothermal compressibility (Pa-1). [Back]

 

d Calculated using the equation isothermal compressibility=adiabatic compressibility+(temperature x expansivity^2)/(density x specific heat)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 κSTCv /Cp. [Back]

 

e Data is calculated from the supercooled water equation of state [2218]. [ Back ]

 

f [2064]. [ Back ]
