Surface tension

11/11/2015 Surface Tension has a library of instrument types for measuring it. Systems based on drops, on bubbles DuNouy Rings and Wilhelmy Plates. The rings and plates work by measuring force. These are the subject of this article "Surface Tension -Rings, Bubbles, Drops and Plates".

This tension force is also called surface tension: For liquids the work ΔW hoop done on the hoop and the work ΔW int required for the surface increase are equal: Figure 3: model experiment on surface tension: Inside a U-shaped wire frame a liquid film is being stretched by the force F acting on a hoop surface tension that you can try yourself. Figure 3 This apparatus, consisting of a C-shaped wire frame and a wire slider, can be used to measure the surface tension of a liquid. Table 1 Surface Tensions of Common Liquids Liquid Surface Tension γ (N/m) Benzene (20 °C) 0.029 Blood (37 °C) 0.058 Glycerin (20 °C) 0.063 Mercury (20 °C) 0.47

25 Sep 2014 ... Surface or interfacial tension is a force per unit length or energy per unit area, which originates from the difference between the intermolecular ... For this reason the surface tension is defined as 'the amount of force (Nm) necessary to expand the surface (m2) of a liquid by one unit'. Therefore, the surface ...

"Surface Tension" was a wild ride, fast paced and high on action. "Surface Tension" starts with a bang and never lets up. Jake is a high school student and a serious cyclist. While out training for a bike race, he sees a plane crash, then is injured and wakes up in the hospital. Surface Tension. Surface tension is measured as the energy required to increase the surface area of a liquid by a unit of area. The surface tension of a liquid results from an imbalance of intermolecular attractive forces, the cohesive forces between molecules:
