Liquid A is known to have a lower surface tension than Liquid B.
Use this fact to predict the result of each experiment in the table below, if you can.
experiment
predicted outcome
OS will be greater than S
OS will be less than Sg
A
OS will be equal to SB
It's impossible to predict whether S or Sg will
be greater without more information.
OF will be greater than F
Identical wire loops are dipped into Liquid A
and Liquid B, so that a film of liquid forms
across the loops (like the bubble solution on a OF will be less than F
child's bubble blowing wand). The width of
each loop is increased slowly and the forces
F and Fg needed to make the loops 5%
OF will be equal to FB
wider are measured.
Small amounts of Liquid A and Liquid B are
sprayed into the air, where they form perfect
spheres with a volume of 25.0 µL. The
diameters of these drops are measured with
a high-speed camera, and their surface areas
S and Sg calculated.
It's impossible to predict whether For F will
be greater without…
