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 ...

The properties of the seawater-air interface were studied by laboratory measurement of the dynamic surface tension of seawater and of samples of artificial seawater on which films of oleic and stearic ...

Bonding over the science of Surface Tension! Why do some things float in water while others sink? The Crew’s depth of knowledge goes WAY below the surface, as they learn all about the molecular bonds ...

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 ...
