Аннотация:A new approach is proposed for studying such behaviors of sessile droplets as surface tension, contact angles, the work of adhesion of droplets of a water phase to a superhydrophobic surface, and the contact diameter and volume of a droplet at negative temperatures. Temperature dependences of the ratio of the liquid surface tension to density are examined for both supercooled water droplets and droplets of 0.5 M aqueous solutions of NaCl, KCl, LiCl, and CsCl salts. The effect the type of cation has on the surface tension of the above solutions is examined in the +25 to -1.5 degrees C range of temperatures. The ratio of liquid surface tension to density for aqueous solutions of chlorides is found to follow a linear Hoffmeister series of cations Na+, K+, Li+, and Cs+.
