weather factors

A dry-bulb temperature of 30°C and a wet-bulb temperature of 29°C were recorded at a weather station. What is the relative humidity?

• Relative humidity is 32%

• Relative humidity is 29%

• Relative humidity is 83%

• Relative humidity is 93%

Air has a dry-bulb temperature of 2 °C and a wet-bulb temperature of -2 °C, what is the relative humidity?

• 11%
• 20%
• 36%
• 67%

If the air is "saturated", that means:

• the air is full of water
• the air is partially full of water
• it's amount of water vapor in the atmosphere right now
• how much liquid water it potentially can hold

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

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

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

The actual amount of water vapor in the air is called

• air pressure
• humidity
• relative humidity
• dew point

What will happen if the relative humidity is 100%, and the temperature begins falling?

• The air will be sticky and uncomfortable
• Dew will form
• The temperature will rise
• The atmospheric pressure will fall
