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