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?

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.
