zking786 Posted April 27, 2006 Share Posted April 27, 2006 How can I do this? Maybe some sort of oscillator? What would you recommend? Link to comment Share on other sites More sharing options...

zking786 Posted April 27, 2006 Author Share Posted April 27, 2006 Why does it decrease the surface tension? Also, what else, possibly a mechanical device would create the desired effect. Additionally, what other solutions would significantly decrease the surface tension of water? Link to comment Share on other sites More sharing options...
gcol Posted April 27, 2006 Share Posted April 27, 2006 Google the difference between adhesion and cohesion. Link to comment Share on other sites More sharing options...
zking786 Posted April 27, 2006 Author Share Posted April 27, 2006 Are you trying to say that soap, or any other solute, when added to the water mixture, will decrease the surface tension? Is this because the cohesive forces of the water decrease due to the presence of a contaminant/solute? Link to comment Share on other sites More sharing options...
chuinhen Posted April 28, 2006 Share Posted April 28, 2006 There is a decrease in cohesive force between water molecules !! when soap dissolve in water , water molecules form hydrogen bonds with the soap molecules .. As a result there is less hydrogen bond formed between water molecules !! Hence the cohesive forces between molecules decreased !! Link to comment Share on other sites More sharing options...
