Which is correct about the density of humid air?
A)Decreases with increasing pressure
B)Varies with air temperature and pressure
C)Increases with increasing air temperature.
D)Not affected by humidity
E)Not affected by humidity.

Question

Quizplus · Accepted Answer

The density of humid air varies with both temperature and pressure. As humidity increases, the density of air decreases at a given pressure and temperature due to the lower mass of water vapor molecules compared to dry air molecules. However, as temperature increases, the density of air decreases at a given pressure and humidity due to air molecules possessing higher kinetic energy and therefore greater intermolecular distance.
