Hi, how can found Bashforth-Adams table(.xls or .doc or .txt,PC's doc),to calc surface tension!Thanks!
Surface tension is a physical property of liquids that causes the surface of a liquid to behave like a thin, elastic membrane. It is caused by the cohesive forces between the liquid molecules, which create a tension on the surface that resists external forces.
Surface tension is typically measured in units of force per unit length, such as newtons per meter (N/m) or dynes per centimeter (dyn/cm). It can be measured using a variety of methods, including the drop weight method, capillary rise method, and Wilhelmy plate method.
Surface tension is affected by several factors, including temperature, type of liquid, and presence of impurities. Generally, surface tension decreases as temperature increases and as the concentration of impurities increases. Additionally, different liquids have different surface tensions due to variations in their molecular structure.
Surface tension plays a significant role in many everyday activities, such as washing dishes, blowing bubbles, and even walking on water. It also affects the behavior of liquids in containers, such as the formation of menisci in drinking glasses and the ability of insects to walk on water.
Yes, surface tension can be manipulated or controlled through various methods, such as adding surfactants (substances that reduce surface tension) or changing the temperature of the liquid. In research and industrial settings, surface tension can also be modified using specialized equipment, such as surface tensiometers.
