WebThe increase in temperature causes a corresponding decrease in cohesive intermolecular forces and this surface tension decreases. For example, the surface tension of water and air is 72.8 mN/m at 20°C, while the surface tension at 25°C is 72.0 mN/m. Figure 5 plots the surface tension of water and air for a range of temperatures from ref. [9]. WebSurface tension is an effect within the surface laye r of a liquid that causes the layer to behave as an elastic sheet. Thus, the surface of any liquid behaves as if it was covered by a stretched membrane. Surface tension is measured in units of force per unit length. cyber hunter pc hack 2022 https://americanchristianacademies.com
