There is an increase in free energy due to interfacial energy is known as a capillarity effect or the Gibbs-Thomson effect. Find the increase in this free energy if the interfacial energy, the molar volume and the radius of the spherical particle are given as 10 (kJ/mm2), 6mm3/mol and 4mm respectively?
Consider for simplicity a wire frame suspending a liquid film. If one bar of the frame is movable it is found that a force 5N per unit length must be applied to maintain the bar in position. If this force moves a small distance so that the total area of the film is increased by 0.5m2. Interfacial free energy per unit area is given as 4 J/m2. Calculate the change in interfacial energy? (Take the area of interface as 2m2)
