Answer to Question #137223 in Mechanics | Relativity for Viccy

Question

How can we explain surface tension phenomenon.

Answer 1

Surface tension is the tendency of fluid surfaces to shrink into the minimum surface area possible. The surface tension can be determined by the difference of interactions between the molecules of the material (fluid) with the molecules of the material in contact.

• Floating needle on the surface of the water
• Cleansing action of soap and detergents on clothes
• Water droplets on some surfaces of the leaves. Droplets look like small bubbles
• Rainproof or waterproof sheets or covering materials (that get rid of water)
• Round bubbles where the surface tension of water provides the wall tension for the formation of water bubbles
