In order to stay at equilibrium, an environment would have to be:

• Hot

• Humid

• Wet

• Sealed

Summer days tend to be more humid than spring days mainly due to:

Relative humidity compares the amount of water vapor in the air to:

• The dew point

• The air temperature

• The maximum potential amount

• The total volume of liquid water in the area

There are 15 water molecules in the air, and the relative humidity is 75 percent. The maximum potential number of water molecules is:

• 15

• 20

• 25

• 30

What must be true if dew forms on grass?

• The sun is about to set

• The grass is wet from precipitation

• More water is evaporating than condensing

• The temperature near the grass is below the dew point

Why do hot, humid days feel so uncomfortable?

• The air has very little moisture

• Our bodies produce less sweat

• Sweat evaporates more slowly

• Humid air does not carry a breeze
