4. assume the temperature of an air parcel increases, while the amount of water vapor in the air parcel is held constant. which of the following statements is true?

group of answer choices

the vapor pressure of the air parcel increases.

the saturation vapor pressure of the air parcel increases.

the vapor pressure of the air parcel decreases.

the saturation vapor pressure of the air parcel decreases.

the relative humidity of the air parcel increases.

The statement that the saturation vapor pressure of the air parcel increases  is true among the given statements.

Option B

Explanation:

The saturation vapor pressure of the air parcel will increase with the increasing temperature. The amount of pressure that each air bubble will exert will increase if the temperature is increased. This would in turn make the vapor molecules saturate just above the water molecules.

This eventually results in precipitation. At high temperature, vapor molecules take less time to saturate over the water as compared to saturation at freezing temperatures which means that rainfall is more when temperature causes saturation vapor pressure to increase.
