Question

At dew point. RH of the air is:

• A. $10\%$
• B. $20\%$
• C. $50\%$
• D. $100\%$

Answer 1

The correct option is D $100\%$

At dew point, RH is 100%

A high relative humidity implies that the dew point is closer to the current air temperature. A RH of 100% indicates that the dew point is equal to the current temperature and that the air is maximally saturated with water.
