Surface TensionHardQuestion 6489

Question

Surface tension of soap solution is less than water because:
  1. A
    Soap is denser
  2. B
    Soap reduces intermolecular forces at surface
    Correct
  3. C
    Soap increases viscosity
  4. D
    Soap reduces temperature

Correct answer

Soap reduces intermolecular forces at surface

Explanation

Surfactants (soap) reduce intermolecular cohesive forces at the surface → lower surface tension.
