Pick out the wrong statement:

• A vapor is termed as a saturated vapor, if its partial pressure equals its equilibrium vapor pressure.
• A vapor whose partial pressure is less than its equilibrium vapor pressure, is termed as a 'superheated vapor'.
• The temperature at which a vapor is saturated is termed as the boiling point.
• The difference between the existing temperature of a vapor and its saturation temperature (i.e. dew point) is called its 'degree of superheat'.
