Soap Film Formation: Explaining the Phenomenon

AI Thread Summary
Dipping a wire ring into a soap solution creates a soap film due to the unique structure of soap molecules and their interactions with water and the wire. As the ring is withdrawn, soap molecules adhere to the wire, forming a film. This phenomenon is influenced by adhesion, cohesion, and surface tension. For further understanding, additional resources on the topic are available. The discussion highlights the scientific principles behind soap film formation.

When we dip a wire ring in a soap solution and then take it out, why does it form a soap film inside? Is there any explanation behind it?

Do you disagree with Wikipedia?

there is explanation for everything :)

the phenomenon concerns structure of soap molecules, their interaction with water and with the wire, adhesion and cohesion, surface tension... You need to read about them.

You see a lot of things here http://www.funsci.com/fun3_en/exper2/exper2.htm
At first, you can think that a layer of soap molecules exist on the water surface and while the wire ring is dipped into the water and withdrawn, some of that layer sticks to the wire.

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
