Question

select the correct answer. why does air at 70% relative humidity and 30°c make your skin feel stickier than air at 70% relative humidity at 10°c? a. warm air rises while cold air falls. b. the warmer air contains less water - vapor per unit of volume. c. the warmer air contains more water - vapor per unit of volume. d. moist air has lower density than dry air does.

Explanation:

At a given temperature, higher relative humidity means more water - vapor in the air. Moist air (higher relative humidity) at a certain temperature contains more water vapor per unit volume compared to dry air (lower relative humidity) at the same temperature. Water - vapor in the air can make the skin feel stickier.

Answer:

C. The moist air contains more water vapor per unit of volume.
