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. a. XA will be greater than XB
b. XA will be less than XB
c. XA will be equal to XB
d. It's impossible to predict whether XA or XB be greater without more information.
