- Fluids have a surface tension, which means that requires that creating more surface requires energy. In order to create more water surface (for example, water spreading over a table top), an energy cost must be paid of about 73 mJ/m2. Lets say you have water in a rectangular container that is 35 cm by 20 cm. Now you want to stretch the longer side by 4 cm. With what force does the surface tension of the water resist that change? Answer in Newtons to four decimal places.Don't provide handwriting solutionsMy question is attached.
