What term describes the condition in which liquid water and vapor coexist at the boiling temperature corresponding to a given pressure?
- A. Superheated
- B. Subcooled
- ✓ SaturationCorrect
- D. Wet quality
Why C is correct
Saturation is the condition where liquid and vapor coexist at the boiling temperature for a given pressure; the saturation temperature and saturation pressure always correspond. Superheated steam has been heated above saturation and contains no liquid; subcooled liquid is below its saturation temperature.
