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/ApproachAt 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 AnswerDisagree (statement is incorrect).
