Research technique of particular physicochemical properties of a fluid

The sectional operation is devoted to examination of a surface-tension of a fluid on a demarcation of heterogeneous mediums.

For definition of a surface-tension the known requirement was utilized, that in a position of an equilibrium the potential energy of system accepts the least value.

As a result of examination the express a method of definition of a surface-tension of fluids and solutions in a wide gamut of change of densities was offered. The advantage of a procedure consists in absence of necessity of definition of an interfacial angle and radius of curvature of a surface of a fluid.
