WebSurface tension is defined as the amount of energy required to increase the surface area of a liquid by a unit amount. So the units can be expressed in joules per square meter (J/m 2 ). You can also think of it as a force per unit length, pulling on an object (Mellendorf, 2002). WebSep 1, 2024 · When a bubble rises to the surface of a liquid, it typically forms a thin, liquid, dome-shaped film supported by the gas trapped inside it. Once this film develops a hole, surface tension causes the film to retract further, and the bubble bursts. In runny, low-viscosity liquids, the bursting process is over in a matter of milliseconds. In ...
