What is Humidity? The amount of water vapor in the air.
What is Relative Humidity? If you compare the amount of water vapor in the air to the maximum amount of water vapor the air could hold, you get relative humidity.
Describe Dew Drops of water that condense from the air onto cool surfaces during the night. In the early morning, drops of dew on plants can sparkle like stars.
Describe Frost The depositing of water vapor from the air onto a surface cooler than 32 degrees F, creating solid ice crystals.
What does it mean when the temperature has reached its Dew Point? The air can hold no more water, and water vapor in the air condenses to form dew.
