The capacity of air for water vapor is primarily a function of the ______of both the air and water vapor.
A)volume
B)temperature
C)density
D)pressure

Question

Quizplus · Accepted Answer

The capacity of air for water vapor increases with temperature. As the temperature increases, air molecules move faster and farther apart, creating more space for water vapor molecules to occupy. Therefore, the warmer the air, the more water vapor it can hold. Choice A, volume, is not a primary factor in determining the capacity of air for water vapor. Density, choice C, is a measure of how tightly packed molecules are and does not directly affect the capacity of air for water vapor. Similarly, choice D, pressure, is a measure of the force exerted by the molecules in a substance, and while it can indirectly impact the capacity of air for water vapor through its effect on temperature, it is not a primary factor in determining capacity.
