GEOL 1340 Chapter Notes - Chapter 5: Mesocyclone, Capillary Action, Evaporation
Document Summary
Earth allows all 3 states to occur naturally. Deposition: vapor attaches to ice crystal causing frost. Heat e must increase motion of molecules to break bonds. Latent heat of melting and freezing each 80 cal/g. Ratio of vapor in air compared to max amt possible in air at given t. Any addition of vapor or decrease in t reduces evaporation rate results in active condensation. Dew-point t: when vapor containing air gets saturated and condensation forms water droplets. Air saturated when dew point t and air t are same. Relative humidity highest at dawn when air t lowest. Saturation vapor p: air that has as much vapor as possible at given t. Warm tropical air over ocean has so much vapor. Mass of vapor per mass of air at any t. Max specific humidity: max mass of vapor in kg of air at t. Describe moisture content of air masses for weather forecasting.
