Surface tension at critical temperature
WebSurface Tension - Surface tension of liquids like water, mercury, oils and more. Triple Point - Triple points for common substances. Universal and Individual Gas Constants - The Universal and Individual Gas Constants in fluid mechanics and thermodynamics. Individual gas constants for the most common gases. 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].
