    • 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.
    • 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.
    • GenSci Item 08-15 www.upcatreview.com Additional water vapor would start to condense .
    • GenSci Item 08-15 www.upcatreview.com In other words, when r elative humidity is 100% , the air is saturated with water vapor.
