  1. 1. GenSci Item 08-15 At the dew point, air has a relative humidity of ______percent.   A. 0 B. 50 C. 70 D. 100 www.upcatreview.com
  2. 2. GenSci Item 08-15 www.upcatreview.com Relative humidity (expressed in percent) is the amount of water vapor present in the air compared to the maximum amount of water vapor air can hold at a given temperature.
  3. 3. GenSci Item 08-15 www.upcatreview.com For example, if the relative humidity is 100%, the amount of water vapor in the air is the maximum amount that can be contained in the air.
  4. 4. GenSci Item 08-15 www.upcatreview.com Additional water vapor would start to condense .
  5. 5. GenSci Item 08-15 www.upcatreview.com In other words, when r elative humidity is 100% , the air is saturated with water vapor.
  6. 6. GenSci Item 08-15 www.upcatreview.com Since dew point is the temperature where condensation begins, it means that at dew point, relative humidity is 100% or it has already exceeded 100%.
  7. 7. GenSci Item 08-15 www.upcatreview.com The air is saturated with water vapor at dew point .
