How does surface tension occur in water

Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible. Surface tension is what allows objects with a higher density than water such as razor blades and insects (e.g. water striders) to float on a water surface without becoming even partly submerged. At liquid–air interfaces, surface tension results from the greater attraction of li… WebJan 30, 2024 · Surface tension of water can cause things to float which are denser than water, allowing organisms to literally walk on water (Figure 2 ). An example of such an organism is the water strider, which can run …

WebJun 8, 2024 · Figure 2.16. 1: Surface Tension: The weight of the needle is pulling the surface downward; at the same time, the surface tension is pulling it up, suspending it on the surface of the water and keeping it from sinking. Notice the indentation in the water around the needle. These cohesive forces are related to water’s property of adhesion, or ... WebFIGURE 2. Next, explain the role of surfactants to students. A surfactant is a substance that reduces the surface tension of a liquid. For instance, a small puddle of water on a desk has high surface tension. But adding a surfactant such as dish soap to the puddle would reduce its surface tension and cause the water to spread out more.
