Identify the incorrect statement from the following options:

Explanation

Option A is correct because saturated vapor occurs when its partial pressure equals the equilibrium vapor pressure. Option B correctly defines superheated vapor as having partial pressure less than equilibrium vapor pressure. Option D accurately describes the degree of superheat as the difference between the vapor's temperature and its saturation temperature. However, option C is incorrect since the boiling point is the temperature at which a liquid boils, not the temperature at which vapor is saturated.
