A psychrometer is used to determine which weather variables?

• wind speed and wind direction

• percentage of cloud cover and cloud height

• air pressure and air temperature

• relative humidity and dew point

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 term "relative humidity" refers to:

• The total amount of water vapor the air can hold at a specific temperature

• The percentage of water vapor present in the air compared to the maximum it could hold at that temperature

• The absolute amount of water vapor in the air

• The humidity level relative to the time of day

The amount of water vapor in the air is known as ___.

• dew point

• humidty

• relative humidity

• rain
