By name or number, identify all of the following three statements that would be true of the boiling of water at a temperature T above its normal boiling point of 373 kelvin. 1) The enthalpy of vaporization for water at T is more positive than the enthalpy of vaporization at 373 kelvin. 2) The Gibbs free energy of vaporization for water at T is more positive than the Gibbs free energy of vaporization at 373 kelvin. 3) The change in internal energy for the boiling of water at T is more positive than the change in internal energy at 373 kelvin.
