An equation of the Laplace pressure derived using the Gibbs thermodynamic method have been discussed and the correct applications of the equation have been substantiated. It has been shown that the expression is applicable only to macrovolumes for the description of surfaces with a constant curvature, but not to the description of nanodisperced systems and surfaces with variable curvature. The expression of the Laplace pressure applicable to a crystal and the cavity limited by a surface of any geometrical shape have been derived
