I Surface Tension and Fluids

  1. Dec 21, 2016 #1
    If you increase surface tension, the molecules at the surface are more strongly pulled in to the center of mass due to the stronger attractive molecular forces.
    -Why is it that when surface tension increases in a liquid, its surface decreases in area, but its volume does NOT change? (Volume remains constant)
    -I thought that when when stronger intermolecular bonds were present, the volume would decrease (what I was taught from my general chemistry courses )

    I think you mean incompressible liquids. For example water. It is very hard to change the density of liquid water.

    Liquids, by typical definition, are very nearly incompressible (though certainly not actually incompressible).
