The difference between saturation vapour pressure and actual vapour pressure at a constant temperature is called ___________________?
Correct answer: C. Saturation deficit
- A. Saturation vapour pressure
- B. Actual vapour pressure
- C. Saturation deficit
- D. Partial pressure
Explanation
Saturation deficit is calculated as saturation vapour pressure minus actual vapour pressure at the same temperature. It indicates how much more moisture the air could hold before becoming saturated.
