| Socratic. Surface tension is a necessary property that contributes tremendously to our lives. It is most prevalent in earth's most important compound, water. "Normal" water at ambient temperature has a high surface tension, but the addition of different chemicals can alter this. read more

Surface tension is an important factor in the phenomenon of capillarity. Surface tension has the dimension of force per unit length, or of energy per unit area. The two are equivalent, but when referring to energy per unit of area, it is common to use the term surface energy, which is a more general term in the sense that it applies also to solids. read more

To measure surface tension using the capillary method, fill a shallow dish with 1 inch of water. Measure the radius of a clear tube, then place the tube in the water and measure how high the water in the tube rises above the water in the container. read more
