experiment predicted outcome Identical wire loops are dipped into Liquid A and L

Question

experiment predicted outcome 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 child's bubble blowing wand). The width of each loop is increased slowly and the force:s Fwill be greater than F F will be less than F F will be equal to FB It's impossible to predict whether FA or FB will FA and FB needed to make the loops 5% wider are measured. be greater without more information. Vwill be greater than V V will be less than V 290. g samples of Liquid A and Liquid B are weighed out, and the volumes V and VR of the samples are measured. will be equal to VB It's impossible to predict whether V or VB will be greater without more information.

Explanation / Answer

surface tension in each liquid is dependent on the nature of the liquid. ... All the experiment show that water, the liquid with the highest density, has the highest surface tension; while alcohol,the liquid with the lowest density, has the lowest surface tension.

Since in above both the cases the density is unknown .

F = T* 2r where T is surface tension of liquid

Since density of liquid is unknown force cannot be determined.

So it is impossible to determine whether Fa or Fb will be greater without more information.

In second case also density is unknown so voulme cannot be measured since. Volume = Mass/ density.

so it is impossible to predict whether Vs or Vb will be greater without more information
