due 11/25/03 at class time.

Below you are given a figure that shows you some measure of the absolute amount of water in the atmosphere as a function of temperature.

1. Trace out the maximum amount of absolute water vapor that can be found in the atmosphere as a function of temperature.

2. What is the relative humidity along this line of maximum amount of absolute water vapor.

3. Use the figure to work out the relative humidity of air with a temperature of 14°C, and a dew point of 7°C.

4. If the relative humidity of air with a temperature of 17°C is 50%, what is its dew point??
