How Thick Is Surface Tension ?
« on: 19/04/2008 17:46:17 »
Dear Tensionologists,

Surface Tension is great !

It's my all time favourite elastic-like force existing upon the surface of a liquid.

Look, here's a lazy paperclip enjoying surface tension luff and goodness !




As a sheep, I am of course an expert on walking on water too but I'd like to know how thick the layer of surface tension is ?....does it make a difference if the water is salty ?

whajafink

It will not affect more than the top two or three layers of atoms. Below that, the forces are equal in all directions. The 'useful' strength of the force depends on the surface it is in contact with or any substance floating on the water or in solution. I am not sure whether ionic solutions affect it but, asymmetrical molecules like detergents definitely do.

THANK YOU VERY MUCH SOPHIECENTAUR.

Gosh...just the top few atoms !!...that's ...well thin !!

Does an asymmetrical molecule then destroy it completely ?

Look at this
http://en.wikipedia.org/wiki/Surfactant


I'm looking at it....it looks like a link !!!

Should I click on it too ?


*five minutes of mass-self-debate*....Ok !

I clicked it...THANK YOU.... :)...so.it seems surfactants reduce surface tension but do not eliminate it altogether !!

Brill !!

Sophiecentaur is wonderful !

This forum benefits so much from peeps like him.

....Lets not forget the wonderful resources these people avail to us......and how ' tolerant' they are of some of our behaviour !! (not mine of course...I'm a good boy)
