Nuclear Physics B, 2004 This paper deals with the thermodynamic properties of a phantom field in a flat Friedmann-Robertson-Walker universe. General expressions for the temperature and entropy of a general dark-energy field with equation of state $p= $ are derived from which we have deduced that, whereas the temperature of a cosmic phantom fluid ($
