Dew Point and Relative Humidity

As the air temperature increases, the air's capacity for water vapor: 

• increases
• decreases
• remains the same
• is unrelated to air temperature and can either increase or decrease

The temperature to which air must be cooled in order to become saturated is the: 

• Relative Humidity
• Mixing Ratio
• Dew Point Temperature
• Wet-bulb Temperature

The sun heats up surface water, causing evaporation (turning a liquid into a gas).  The water vapor then rises into the air creating....

• rain
• pollution
• fog
• humidity

What is relative humidity?

• humidity that is related to other humidity
• condensation
• clouds
• the amount of water in the air compared to the amount of water the air can hold - a ratio

If the air is only holding one-third as much moisture as it can possibly hold, what is the relative humidity?

• 50%
• 25%
• 33%
• 67%

Which type of air has a relative humidity of 100%?

• space
• hot
• dry
• saturated

The temperature at which air is saturated with water vapor and condensation occurs is called

• humidity
• air pressure
• dew point
• relative humidity

Which type of air holds more water 

• warm 
• cold 

What kind of air describes "humid" air? 

• warm and wet 
• cold and dry
• cold and wet
• warm and dry

Relative humidity is a good measure of how humid it is outside.

• True

• False
