Surface Energy

Book Abstract

Surface Energy is the amount of energy needed to create a new surface area. It?s a measure of how attracted a material?s molecules are to each other. Surface energy quantifies the disruption of intermolecular bonds that occurs when a surface is created. It is also called surface free energy or interfacial free energy. In simple language, surface energy can be defined as the work per unit area done by the force that creates the new surface.
