When a gradient in this causes mass transfer of fluids, that phenomenon is known as the Marangoni effect, and this quantity is multiplied by volume to the two thirds in an equation which relates it to temperature, the Eotvos rule. The fact that this acts as a proportionality constant between the work done on a liquid-vapor interface and the change in the interfacial area is demonstrated by the Young-Laplace equation, and this phenomenon causes cohesion of molecules, which can explain capillary action. For 10 points, ide

For 10 points, identify this phenomenon which is reduced by surfactants and which allows insects to walk on water.
