When evaporation and condensation occur at the same rate, the air is described as?

• A. Dry
• B. Saturated
• C. Humid
• D. Moist

Answer: (B)

The air is saturated. When evaporation adds water vapor to the air and condensation removes it at the same rate, the air holds the maximum amount of water vapor possible for the given temperature. That balance means the relative humidity is at 100%, and any extra vapor would condense. Dry air has little water vapor, and terms like humid or moist describe noticeable moisture but not necessarily the maximum capacity. A saturated state is what you get when evaporation and condensation are in perfect balance.
