For aqueous solutions with a solute mole fraction less than 1%, the Szyskowski equation can be used to compute this value. In the Gibbs isotherm, the value capital gamma-sub-i for each solute is equal to minus one over RT times the partial derivative of this value with respect to the natural-log concentration of that solute, keeping P and T constant. For two adjacent bubbles of unequal radii, the pressure difference between the bubbles is equal to twice this value times the difference in reciprocal radii of the bubbles. Under conditions of constant temperature and pressure, this value is given by the partial derivative of Gibbs free energy with respect to area. This quantity varies inversely with volume to the two-thirds power in Eotvos's rule. For 10 points, name this elastic tendency of liquids to contract in surface area.
