n: the tendency of liquids to maintain as small a surface as possible. It is caused by the cohesive attraction between the molecules of liquid.

n: Surface free energy that exists between a liquid and air. Surface tension can be observed as a curved meniscus in a small tube of the liquid. This energy barrier prevents a liquid (such as water) from spontaneously mixing with air to form a foam. To make

a measurement of the difficulty of moving a fluid past another fluid (see interfacial tension). The resistance is created by the cohesion forces between the liquid molecules. The forces make it more difficult to pass fluids past a surface. Surface tension
