 1. 

Cold water provides more water vapor than warm water.
 

 2. 

Condensation is the change in matter from a gaseous to a liquid phase.
 

 3. 

Evaporation is the process by which molecules spontaneously change from a liquid to a gaseous state.
 

 4. 

Dewpoint is the temperature at which water vapor evaporates into liquid water
 

 5. 

Without dust particles, pollution, or smoke in the atmosphere, clouds cannot form.
 

 6. 

As air rises it is compressed. In other words, pressure INCREASES as air rises.
 

 7. 

In order for a cloud to form, humid air must be cooled below its dewpoint.
 

 8. 

There would be less humidity in the air above a warm lake than a cold lake.
