If atmospheric temperature and dew point are nearly equal, then the relative humidity is_______________?
Correct answer: C. Almost 100%
- A. Zero
- B. 50%
- C. Almost 100%
- D. unpredictable
Explanation
When air temperature is close to its dew-point temperature, it is nearly saturated with water vapour. Saturated air has a relative humidity close to 100%.
