Molecular formula : CAS :
nature : the pure substances or mixtures, to a certain temperature, pressure, gas, liquid two-phase equilibrium, a balance of saturated steam as gas, liquid balance as saturated liquid. When the temperature is higher than the saturation vapor temperature, or pressure below the saturation vapor pressure, the system is single-phase vapor state, this time in relation to the steam vapor, then known as superheated vapor. "Overheating" does not necessarily mean high temperature. For example, the 100K 0.1MPa and the oxygen is superheated vapor, as 0.1MPa under oxygen saturation vapor temperature of 90.2K.
