  • Applying Henry's Law

    The rate of condensation is proportional to the exposed surface area of liquid and to the number of molecules in the vapor phase. This number is directly proportional to the pressure exerted by the vapor.

  • Evaporation and its Effects on PCP and Cresol

    Molecules are becoming vapor and vapor molecules are becoming liquid at the same rate. The process of evaporation from a pond is considered an open system, so water vapor is free to float or be blown away from the pond.
