One kg of saturated steam at 100°C and 1.01325 bar is contained in a rigid walled vessel. It lias a volume of 1.673 m3. It cools to 98°C ; the saturation pressure is 0.943 bar ; one kg of water vapour under these conditions has a volume of 1.789 m3. The latent heat of condensation (kJ/kg-1 ) under these conditions is

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'.
