Question 1341Navigation General
70% to passAs the temperature for a given mass of air increases, the _______________.
The correct answer is D) relative humidity decreases. As the temperature for a given mass of air increases, the relative humidity decreases. This is because relative humidity is a measure of the amount of water vapor in the air relative to the maximum amount of water vapor the air can hold at a given temperature. As the temperature rises, the air can hold more water vapor, causing the relative humidity to drop, even if the actual amount of water vapor in the air remains constant. The other options are incorrect because: A) the dew point is the temperature at which the air becomes saturated with water vapor and is not directly affected by changes in temperature, and B) the dew point also does not increase as the temperature increases.
