Uses formula: obtained from CHERIC3edit Phase diagramedit Liquid/vapor equilibrium thermodynamic dataThe table below gives thermodynamic data of liquid CO2 in equilibrium with its vapor at various temperatures. Heat content data, heat of vaporization, and entropy values are relative to the liquid state at 0C temperature and 3483 kPa pressure. To convert heat values to joules per mole values, multiply by 44.095 grams/mole. To convert densities to moles/liter, multiply by 22.678 cm3-mole/liter-gram.
