Molecules of water are more attracted to each other than other … WebElectric and magnetic fields have been reported to lower the surface tensions of natural water by up to 8% [ 735 ]. However, it has been noted elsewhere that surface tension measurements are too sensitive to impurities to provide reliable data [ 979 ].
Web1 Aug 2024 · Solution 1. Reduction of surface tension of water can be done in several ways. A few of them are as follows: Surfactants are compounds that lower the surface tension of a liquid like water, the interfacial tension between two liquids, or that between a liquid and a solid. Surfactants may act as detergents, wetting agents, emulsifiers, foaming ... Web5. Water Striders. Water striders are a family of insects that are capable of walking on water. They are also known by other common names such as water skeeters, water scooters, water bugs, pond skaters, water skippers, Jesus bugs, or water skimmers.
