Lesson 18

Humidity and Condensation

Humidity - density of water vapor in the air; dependent on temperature and pressure

• measure of the amount of water vapor in the air
• Temperature that water condenses indicates how much water vapor is in the air

When the temperature is colder then the water vapor in the air is less dense and as the temperature rises, the density increases.

Relative Humidity - amount of water vapor in the air compared to water vapor possible for a specific temperature; indicated as a percent

• Upper limit to amount of water vapor that is possible at a given temperature

Practice Problems

5) 2.2 mol/1000 L

7) 1.6/4 = .4 mol/1000 L
