Relative humidity vs. moistening: evaluate the statement. Statement: “The relative humidity decreases as air gets wet (more moisture content).” Decide whether the statement is correct or incorrect.

Difficulty: Easy

Agree (statement is correct)
Disagree (statement is incorrect)
True only at constant dry-bulb temperature
True only above the dew-point temperature

Correct Answer: Disagree (statement is incorrect)

Explanation:

Concept/Approach
At a given temperature, adding moisture moves the state toward saturation; thus the relative humidity rises, not falls. While RH also depends on temperature, the blanket statement that RH decreases as air gets wetter is incorrect.

Final Answer
Disagree (statement is incorrect).
