Exam 4: Atmospheric Humidity

If the air temperature increased, with no addition or removal of water vapor, the actual vapor pressure would​

Suppose the dew point of cold outside air is the same as the dew point of the air indoors. If the door is opened and cold air replaces some of the warm air, then the new relative humidity indoors would be​

The instrument that measures humidity by measuring the amount of radiant energy absorbed by water vapor is the​

Suppose saturated polar air has an air temperature and dew point of -10 $\degree$ C, and unsaturated desert air has an air temperature of 35 $\degree$ C and a dew point of 10 $\degree$ C. The desert air contains ____________________ water vapor and has a(n) ____________________ relative humidity than the polar air.

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

During the great Chicago heat wave of July 1995 the afternoon air temperature reached 106 degrees Fahrenheit at Midway Airport, followed by an overnight low temperature of only 84 degrees Fahrenheit. Many residents either had no air conditioning or could not afford to use it. More than ____ deaths occurred over five days.​

A high water vapor pressure indicates a(n)​

A region can have a high specific humidity and low relative humidity because large amounts of water vapor in the air and very high air temperatures will cause the specific humidity to be high, but the relative humidity to be low.

Which of the following is the BEST indicator of the actual amount of water vapor in the air?​

Saturation is more likely to occur in cool air than in warm air.

The total mass of water vapor stored in the atmosphere at any moment is about ____ of the world's supply of precipitation.​

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.

​What will occur if a glass of water at a stable temperature is surrounded by saturated air?

____________________ represents the water vapor density (mass/ volume) in a parcel of air, and normally, is expressed as grams of water vapor in a cubic meter of air.

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

A strand of human hair is known to increase by 2.5 percent as the relative humidity increases from 0 to 100 percent.

As the air temperature increases, with no addition of water vapor to the air, the relative humidity will ____________________.

Days with temperatures above 90 degrees Fahrenheit and above 90 percent humidity are common in the southern United States.

The partial pressure of water vapor is called the ____.​

Which of the following will increase the relative humidity in a home during the winter?​
