How can you reduce the surface tension of water?
How can you reduce the surface tension of water? Some liquids such as oil and kerosene can destroy surface tension in water. Adding soap or detergent reduces surface tension in water. Increasing the temperature of the liquid reduces surface tension. Does water have surface tension in a vacuum? Yes, water still has surface tension in a vacuum. Water/vacuum surface tension is 72.8 dyn/cm experimentally according to Zhang et al. J. Chem. What is the surface tension at the air water interface? For example, the surface tension of water and air is 72.8 mN/m at 20°C, while the surface tension at...
