WebAbstract. Consistent values for the surface tension of mercury in a high vacuum (air pressure less than 1.2× 10−5 mm Hg throughout the period of experimentation), ranging from 438.4±0.3 dynes per cm at 12.5°C to 423.9±0.6 dynes per cm at 67°C, have been found by a modified flat-drop method. In evaluating them Worthington's equation σ ... WebThe model of a liquid surface acting like a stretched elastic sheet can effectively explain surface tension effects. For example, some insects can walk on water (as opposed to floating in it) as we would walk on a trampoline—they dent the surface as shown in Figure 2(a).
