The mass of water vapor in a given volume of air is called ____.​

Comparing the three phases of water,molecules in the solid phase (ice)have the highest vibrational speed,and molecules in the gaseous phase (water vapor)have the slowest vibrational speeds.

If all of Earth's water vapor were to suddenly condense and fall as rain,it would be enough to cover the entire globe with ____ of water.​

When the air temperature increases,the saturation vapor pressure decreases.

Water in a glass will evaporate more quickly on a windy,warm,dry summer day than on a calm,cold,dry winter day.

When both the air temperature and relative humidity are high and the air is nearly saturated with water vapor,body moisture does not readily ____.​

The higher the temperature of a gas,the ____________________ its molecules move.

Condensation occurs primarily when air is cooled,because as temperature drops the speed of the water molecules increases.

What is meant by the terms water vapor saturation and saturation vapor pressure? Why does the saturation vapor pressure increase with increasing air temperature?

____ law of partial pressure describes that the total pressure inside an air parcel is equal to the sum of all pressures of the individual gases present in the air parcel.​

The hot,desert air of the Sahara often contains ____ water vapor than the cold,polar air farther north,therefore has a ____ specific humidity.​
