The surface tension of a liquid is a measure of the cohesive forces that hold the molecules together. It is responsible for a water drop assuming a spherical shape and for the effects of surfactants ...

HOPING it may be of interest to some of your readers, I venture to send you the following description of a simple experiment on surface tension. A drop of water hanging from the end of a vertical ...

The paper clip is on the water but is not floating like a boat which is less dense than water. The paper clip is more dense than water but can rest on the surface of the water because of the water's ...

A tensiometer is an instrument used to measure the surface tension (γ) of liquids or surfaces in the domain of physics. Surface tension is the contractive quality of the surface of a liquid that ...

In its most basic form, surface tension is the tendency of liquids to bead up rather than spread out because they are more attracted to themselves (cohesion) than they are attracted to other things, ...
