Surface Tension and Bubbles Surface tension is a force caused by the attraction of liquid molecules on a boundary surface for each other. It acts tangential to the surface and is modeled as a single number, the surface tension Consider a square film on a wire frame. The bottom edge is movable and, when the frame is vertical, as shown, the surface tension of the film pulls...

5 6 Liquid X is known to have a lower surface tension and lower viscosity than Liquid Y. Use these facts to predict the result of each experiment in the table below, if you can. experiment predicted outcome 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 childs bubble blowing wand). The width of each loop is increased slowly and the forces...

1.Pentane (C5H12) has a surface tension of 1.61 x 10 ^ -2, while ethanol (C2H5OH) has a surface tension of 2.23 x 10 ^ -2, which would have the highest viscosity? A) pentane B) ethanol C) both have the same viscosity D) cannot be determined with the information provided 2.Which of the following is true for surface tension? l is a measure of the surface area exposed by the liquid ll increases with increasing intermolecular attraction forces lll decreases with...

In the sport of bubble soccer, contestants wrap inflatable bubbles and attempt to play a "normal" game of soccer. Unlike soccer, collisions are an expected and somewhat deliberate part of the game of bubble soccer. In the instance shown, players A and B converge on the ball. Player A is moving in the +x direction with a speed of 6 m/s. Player B is moving in the +y direction with a speed of 3 m/s. Player A has a mass...

Compare two turntables, A and B. The turntables have the same surface, but turntable A has twice as big radius than turntable B. We can predict that the maximum frequency of rotation at which coin still does not slide off the turntable A is A) twice as big as the frequency for turntable B B) same as the frequency for turntable B C) 1/2 of the frequency of turntable B D) 21/2 times the frequency of turntable B E) 2-1/2...

2) Two copper wires have the same voltage across them and the same length, but one wire has twice the diameter as the other. How much power is dissipated in the wire with twice the diameter compared to the other wire?A) 1/4 as much B) 1/2 as much C) the same amount D) twice as much E) four times as much
