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' |
