      • Humidity
      • Humidity - The amount of water vapor present in the air.
        • Air does not always contain the same amount of water vapor.
      • At warmer temperatures, the molecules of water vapor in air move quickly and don’t easily come together.
      • At cooler temperatures, molecules in air move more slowly.
      • The slower movement allows water vapor molecules to stick together and form droplets of liquid water.
      • Condensation - the formation of liquid water from water vapor.

      • Relative
      • Humidity
      • Relative Humidity - is a measure of the amount of water vapor present in the air compared to the amount needed for saturation at a specific temperature.
      • The amount of water vapor in the air at any given time is usually less than that required to saturate the air.
      • The most common units for vapor density are gm/m 3.
    • RELATIVE HUMIDITY SCALE. =)
