==Liquid/vapor equilibrium thermodynamic data== The 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 0&nbsp;°C temperature and 3483&nbsp;kPa pressure. To convert heat values to joules per mole values, multiply by 44.095&nbsp;g/mol. To convert densities to moles per liter, multiply by 22.678&nbsp;cm³&nbsp;mol/(L·g). Data obtained from ''CRC Handbook of Chemistry and Physics'', 44th ed. pages 2560–2561, except for critical temperature line (31.1&nbsp;°C) and temperatures −30&nbsp;°C and below, which are taken from ''Lange's Handbook of Chemistry'', 10th ed. page 1463.
