Vapour which is at a pressure smaller than the saturation pressure for the temperature involved is called a _____________ vapour?
Correct answer: D. Superheated
- A. None of these
- B. Desuperheated
- C. Non-condensable
- D. Superheated
Explanation
At a given temperature, a vapour pressure below the saturation pressure indicates that the vapour is superheated. Saturated vapour has pressure equal to the saturation pressure at that temperature.
