13-14 Continued Air is supersaturated when the partial pressure of water exceeds the saturated vapor pressure. Dew point is the temperature where partial pressure of water equals the saturated vapor pressure of water.

13-15 Diffusion Diffusion is the movement of particles from an area of high concentration to an area of low concentration. A concentration gradient can be calculated from (C1 - C2 )/Dx Rate of diffusion (J) can be calculated from… J=DA (C1 - C2 )/Dx …this equation is Fick’s law See Example 13-19 pg 410
