WebApr 17, 2024 · Surface tension is a force which causes a layer of liquid to behave like an elastic sheet or skin. Molecules of water are more attracted to each other than other molecules, as water is a polar molecule. The positive hydrogen end of one molecule is attracted to the negative oxygen end of another water molecule. sutton bonington parish council minutesWebMay 1, 2001 · Decreasing the surface tension of water is easy using molecules called surfactants. One part of a surfactant molecule is attracted to water while another part is repelled. As a result, surfactants readily position themselves at the air-water interface and can significantly lower the surface tension, by over a factor of two in some cases. sutton bonington term datesWebFigure 6: The fluid pipe generated by a falling water jet impinging on a contaminated water reservoir.
