The relative humidity of air decreases in-spite of an increase in the absolute humidity, when the____________________?
Correct answer: A. Temperature rises
- A. Temperature rises
- B. Pressure rises
- C. Temperature falls
- D. Pressure falls
Explanation
Relative humidity is the ratio of actual water-vapour pressure to saturation vapour pressure. When temperature rises, saturation pressure increases sharply, so relative humidity can fall even though the actual moisture content increases.
