Document Summary
Partition coefficients between fish and water are similar to. Kow; based on empricical data fish are 5% lipid, octanol is a good substitute for lipid. The partition coefficient(k) is the ration of the concentrations in two phases at equilibrium. The temperature at which a common compound coverts from a liquid. It is important because it is related to how chemicals volatize in the environment. Temperature and pressure are important, however in the environment the pressure fluctuation is minor. Oth law: when bodies are at thermal equilibrium, there is not net flow in either direction, their temperatures are equal. Conservation of energy, energy can be destroyed or created, can be redistributed. Systems will always seek to minimize the free energy, take the lowest energy state. The vapor pressure is the solubility of a pure solute in air, the maximum partial pressure the solute can achieve in the air phase under selected conditions.
