1. Dew Point The temperature that the air needs to be cooled to reach saturation (100% humidity) Cooling the air below the dew point causes the water vapor to condense Dew, fog, clouds, frost form

2. The air temperature is 60°F and the dew point is 59°F. What does this indicate about the weather?

3. If the dry bulb temp. is 22°C, And the wet bulb is 16°C, What is the dew point?

4. Cold Drinking-glasses Chill Surrounding Air to the Dew-Point Condensation on Cold Drinking-glasses

7. Is there a PATTERN to how much water vapor the air can hold at increasing temperatures?

9. Dew Point Temperatures

11. Bell work 1.How does dew point temperature compare to the temperature that condensation will occur? 2.What weather is indicated if the wet bulb and dry bulb temperature is the same. 3.On a clear day, relative humidity will ________ from sunrise to sunset.
