Explanation:
Therefore, energy is needed to move molecules from the bulk of the liquid to the surface. ... Surface tension is the interfacial tension of a liquid-gas interface. In paints and inks the 'gas' phase is most often the air above the system. Surface tension values of some pure liquids at room temperature.
