Question

We feel most comfortable at relative humidity at:

• A. < 50%
• B. 50%
• C. > 50%
• D. 100%

Answer 1

Answer: (B)

50%

Relative humidity is the ratio of the current absolute humidity to the highest possible absolute humidity which depends on the air temperature. A reading of 100 percent relative humidity means that the air is totally saturated with water vapour and cannot hold any more, creating the possibility of rain. We feel most comfortable at relative humidity 50%.
