WebThe surface free energy is defined as the energy required to increase the surface between vapor and liquid by one unit surface, expressed in mJ/m 2 or erg/cm 2. The surface free energy is equivalent to a line tension acting in all directions parallel to the surface, which is called surface tension and is usually epressed in mN/m or dyne/cm. WebApr 10, 2024 · Surface Energy (E) = S x ΔA. where, S = surface tension and ΔA = increase in surface area. Unit of Surface Energy: SI Unit of Surface Energy is N/m. Surface Energy … WebChapter 1.
