Exam 4: Atmospheric Humidity

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

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

The ratio of the mass of water vapor in a given volume (parcel)of air to the mass of the remaining dry air describes the​

Which of the following always decreases in a rising parcel of air?​

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

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.​

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

____ 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.​

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.

The psychrometer is used to obtain ____ and ____.​

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

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

During the winter,high relative humidity can irritate the mucus membranes in the nose and throat.

Sun's energy transforms enormous quantities of liquid water into water vapor in a process called ____.​

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

On a warm and windy day evaporation will be ____.​

High relative humidities are normally found in the tropics and near the poles,where there is little separation between ____________________ and ____________________.

A high water vapor pressure indicates a(n)​

Explain why,at temperatures below freezing,the saturation vapor pressure over water is greater than the saturation vapor pressure over ice.
