Web27 sep. 2024 · Surface energy is a key property of solid materials, like substrates that must be coated. Surface energy is the interfacial tension of a solid-gas interface. The property is represented by the symbol γsg, with the subscript ‘s’ standing for solid and ‘g’ for gas. The gas above the solid surface is most often air. WebOne method to measure the surface tension of a liquid is to measure the height the liquid rises in a capillary tube. By setting the two forces above equal, we find the surface tension to be: For pure water and clean glass, the contact angle is nearly zero. Web4 nov. 2024 · The unit for surface tension is one newton per meter (N/m). A Newton is equal to 1 kg-m/s 2. To work out the units on your own, simply solve the equation with just units. S = kg/m 3 * m * m/s 2 * m. Two of the meter units cancel out two of the per meter units and you are left with 1 kg-m/s 2 /m or 1 N/m. 3. oh how i wish you were here lyrics
