Question

Liquid X is known to have a higher surface tension and higher viscosity than Liquid Y Use these facts to predict the result of below experiment:

Experiment:
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 FX and FY needed to make the loops 5% wider are measured.
predicted outcome:
O FX will be greater than FY
O FX will be less than FY
O FX will be equal to FY
O It's impossible to predict whether FX or FX will be greater without more information.

Answer 1

O FX will be greater than FY

Step-by-step explanation:

Surface tension can be defined as the force required to stretch one film of a given fase (usually with liquids).

This required force is proportional to the liquid's surface tension. This means that the higher the surface tension, the higher the required force to stretch it is.
