![]() Surface tension = Force per unit length in N/m. Surface tension has the unit of force/unit length or energy/unit area. This liquid property is known as surface tension. Adhesion allows it to adhere to another body.Īt the interface between a liquid and a gas, that is, in a liquid, the out-of-equilibrium force between molecules creates an imaginary surface layer, which exerts a tension force on the surface.Cohesion allows a liquid to resist tensile stress.Liquids have both cohesion and adhesion and both are forms of molecular attraction. It is also described as the tensile force on the surface of the liquid in contact with a gas, such that the contact surface acts as a membrane under tension. The surface energy per unit area of the interface is known as the surface tension coefficient of surface tension. Read Also: What are the Types of Fasteners?
