With increase in absolute humidity, the dew point of an unsaturated mixture of air and water vapor (at constant pressure and temperature) ?
Correct answer: A. Increases
- A. Increases
- B. Remains unchanged
- C. Decreases
- D. Decreases linearly
Explanation
Dew point is the temperature at which the existing water vapour becomes saturated. Increasing absolute humidity increases the water-vapour partial pressure, so saturation is reached at a higher temperature.
