thermodynamics properties of pure substances
... It is now noted that state 1 in Figure 2-3 (page 3) is called a compressed liquid state because the saturation pressure for the temperature T1 is less than P1. Data for water compressed liquid states are found in the compressed liquid tables, Table A-7. Table A-7 is arranged like Table A-6, except t ...
