For 10 points, name this measure of adjusted pressure, the tendency of a substance to escape a phase, symbolized f.
Environmental media with high capacities for this quantity can keep greater amounts of a particular chemical while maintaining low values for this quantity. Mayer's series expansion for pressure uses powers of this quantity. At constant temperature, the change in the logarithm of this quantity is proportional to the change in the chemical potential. In a (*) mixture, it measures the difference between the actual partial molar Gibbs and the ideal partial molar Gibbs. Raoult's law can be derived by setting this quantity equal for two different phases at equilibrium from the Lewis-Randall rule. It is used in non-ideal gases and has units of pascals.
