Dew Point and 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 time of day when the relative humidity reaches a maximum value is usually

• at the time when the air temperature is highest 
• in the middle of the afternoon 
• at the time when the air temperature is lowest 
• just before sunrise

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

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

Choose the best definition for Relative Humidity

• How many grams of water vapor are in the air divided by the amount the air can hold

• What temperature the air will become saturated with air

• The amount of humidity necessary to create dew

• The opposite of humidity
