Geography 1111 9-2 Notes MOISTURE IN THE ATMOSPHERE 1. Unique properties of water 2. Vapor pressure 3. Saturation 4. Relative humidity 5. Dew point temperature HYDROGEN BONDING Water molecules are asymmetrical o O on one side, H on the other Chemically, this creates a charge imbalance o H 2 O is dipolar molecule o O side is neg charge, H side is pos charge Since opposite charges attract, causes water molecules to align, joined by hydrogen bonds. Unique Properties of Water Water has a high boiling point and a low freezing point Water has highest heart of vaporization (latent heat) of all liquids Moist air possesses high latent heat content, high energetic potential Water has a high heat storage capacity Liquid water is denser than ice, so it floats. Water carries an electrical charge (good solvent) o Causes water molecules to cohere to one another o Causes them to adhere to other surfaces o Creates capillary action Atmospheric Humidity Terms Humidity- amount of water vapor present in the air
