Identical wire loops are dipped into Liquid X and Liquid Y, so that a film of liquid forms across the loops (like the bubble solution on a child's bubble blowing wand). The width of each loop is increased slowly and the forces and needed to make the loops wider are measured. Which of the following is the predicted outcome if liquid x has a lower surface tension than liquid y? will be greater than
will be less than
will be equal to
It's impossible to predict whether or will be greater without more information.
