Determination of the surface tension of the pull ring. P3040201

You can get the concept of:
Surface energy, surface tension, wettability, critical point.

Principle:
Molecules in a liquid subjected to forces defined surroundings of this molecule. Surface tension is calculated from izhodya diameter of the ring and forces acting on it at the time of separation. In this experiment, determined by the surface tension of olive oil, water and aqueous mixtures of methanol.
