Surface Tension
My problem was to find out how to test or measure surface tension. I think the
reason of some of the force in surface tension is cohesion and gravity. Surface Tension is
the condition existing at the free surface of a liquid, resembling the properties of an
elastic skin under tension. The tension is the result of intermolecular forces exerting an
unbalanced inward pull on the individual surface molecules; this is reflected in the
considerable curvature at those edges where the liquid is in contact with the wall of a
vessel. Because of this property, certain insects…
