1. SOMEWHERE OVER THE RAINBOW
Humidity

2. Humidity- the actual amount of water vapor in the air
Capacity- the maximum amount of water vapor that can be present in air at a given temperature
Relative Humidity- a comparison of the actual amount of water vapor in the air with the maximum amount of water vapor that can be present in air at a given temperature (given as a percent)
rh =
humidity x 100
capacity

3. Assuming the humidity remains constant:
As the temperature increases the capacity and the relaive humidity
increases
decreases

4. Assuming the humidity remains constant:
As the temperature decreases the capacity and the relative humidity
decreases
increases

5. Dew Point- is the temperature at which condensation occurs
Saturation- is when the air is holding all the water vapor it can at a given temperature

6. The relative humidity when the air is saturated is %
100

7. When the air is very humid there is little room for more water vapor, therefore there will be little if any
When the air is very dry there is a great deal of room for more water vapor, therefore there will be a great deal of
evaporation
evaporation

8. When an object is wet and the water is evaporated the water must energy to evaporate the water and some of that energy comes from the object making the object
gain
cooler

9. When an object is warm and wet, the water can not be
because the air is very humid, the water doesn’t energy to evaporate the water and the object remains and wet
evaporated
gain
warm
