A psychrometer is an instrument for measuring __________ humidity.  

• Low 
• Relative
• Absolute
•  High

Humidity can be found by comparing the temperatures of _________________.  

• barometers
• wet-bulb and dry-bulb thermometers
• Hydrometers
•  Anemometers

Air with a relative humidity of 100 percent is said to be __________________. 

• Saturated
• Unsaturated 
•  Hot 
• Muggy 

Dew Point is the

• temperature air cools down to reach condensation (or turn into a liquid)
• temperature where ice melts to liquid water
• temperature where ice turns directly into water vapor
• time of day when dew on the ground disappears

Dew is most likely to form 

• after heavy rain on a humid day
• when humid air contacts cold ground
• when the snow on the ground melts
• during windy nights when it rains

Where can you find water vapor in the air? 

• only in clouds             
• only as rain                     
•  everywhere

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
