Does surface tension change with container length?

[techno]

By definition, surface tesnsion is the force at the surface of separation of two fluids and it's unit is N/m. my doubts are
1. Is it the force per unit length?
2. Does Surface tenson changes with change in lenth of the liquid container?

Yes. No. Surface energy changes with surface area; surface tension times the area of the surface bounding a phase = surface energy --- this is what drives the formation of spherical bubbles, droplets, etc.
