Surface tension

  1. Nov 25, 2014 #1
    What's the difference between surface tension and capillary force?
    Surface tension, a tensor, is the force per unit length. Again surface energy is the energy required to increase the surface area by one unit. Is the surface tension a capillary force?

    Can you not tell one from the other?

    Capillary action and surface tension are names for related but not identical phenomena.

    Capillary force is one of the phenomenon due to surface tension.

    Capilary effects are due to both: adhesive forces to the walls, and cohesive forces within the fluid. Surface tension is just cohesion.
