High relative humidity decreases the evaporative process and as the temperature is increased, the relative humidity decreases. The comfort range for human body is the ambient temperature of 22 to 27°C with relative humidity ranging from _______________ percent ?
Correct answer: C. 45 to 50
- A. 5 to 10
- B. 15 to 25
- C. 45 to 50
- D. 75 to 80
Explanation
Human comfort near 22 to 27°C generally requires moderate relative humidity, about 45 to 50 percent. Very low humidity causes dryness, while very high humidity restricts evaporative cooling from the skin.
