Question

Saturated air has a relative humidity (RH) of

• A. 0%
• B. 75%
• C. 50%
• D. 100%

Hint:

"Saturated" in the context of humidity means "100% full". The air cannot hold any more moisture as vapor.

Answer 1

The Correct Option is D

Step 1: Define Relative Humidity (RH). Relative humidity is the ratio of the actual amount of water vapor present in the air to the maximum amount of water vapor the air could hold at that specific temperature.

Step 2: Define "saturated air". Saturated air is air that is holding the absolute maximum amount of water vapor possible at its temperature. Any additional water vapor would condense into liquid water.

Step 3: Combine the definitions. Since saturated air contains the maximum possible amount of water vapor, the actual amount is equal to the maximum possible amount. Therefore, the ratio is 1, which is expressed as 100%.
