Surface tension of ethanol solution
WebAug 14, 2024 · Surface tension is the energy required to increase the surface area of a liquid by a unit amount and varies greatly from liquid to liquid based on the nature of the intermolecular forces, e.g., water with hydrogen bonds has a surface tension of 7.29 x 10-2 J/m 2 (at 20°C), while mercury with metallic bonds has as surface tension that is 15 ... WebAbstract Density, viscosity, and surface tension of liquids are important physicochemical properties which affect mass and heat transfer in solutions. The density, viscosity, and surface tension of binary mixture of water + ethanol at 293, 298, 303, 308, 313, 318, and 323 K are reported and compared with the available literature data.
