Physical Surfaces deals with the basic concepts of the physics of surfaces, including the nature of the surface pressure of unimolecular films and the equilibrium pressure of these films. The effect of particle size on capillary pressure, the surface energy and the cuticular energy of solids, and the fundamentals of wetting are also examined. This book is comprised of nine chapters and begins with a discussion on the mechanics and physical chemistry of liquid surfaces, with emphasis on capillarity and surface tension. The following chapters focus on liquid-liquid interfaces, foams and emulsions, and solid surfaces. Interfacial tension is analyzed in relation to miscibility and surface tension, along with contact angles in gas-liquid-liquid systems. The chapter on wetting looks at theories of contact angle, its measurement, and hysteresis. Adsorption and electric surface phenomena are also explored, together with adhesion and friction. This monograph will be a valuable resource for physical chemists and physicists.
