Dewpoint & Relative Humidity Questions

What is the dew point?

• The temperature at which water vapor condenses into liquid water

• The temperature at which water freezes into ice

• The temperature at which water evaporates into water vapor

• The temperature at which water boils into steam

What is relative humidity?

• The measure of how much water vapor the air is holding compared to how much it can hold at that temperature

• The measure of how much water vapor the air is holding compared to the total amount of water in the air

• The measure of how much water vapor the air is holding compared to the amount of particulate matter in the air

• The measure of how much water vapor the air is holding compared to the amount of condensation nuclei in the air

Why does warm air hold more water vapor than cold air?

• Because molecules in warm air move faster and are more spread out

• Because molecules in warm air move slower and are more spread out

• Because molecules in warm air move faster and are closer together

• Because molecules in warm air move slower and are closer together
