Question
Which of the following describes surface tension in water?
Solution
Surface tension in water is a property that arises due to the cohesive forces between water molecules. These forces create a "film" on the water's surface, making it behave somewhat like a stretched elastic sheet. This is why small objects, like insects or paper clips, can sometimes float on the surface of water without sinking. The water molecules at the surface are pulling together, creating a tight network that can support the weight of these small objects. This is also why water droplets form spheres - the surface tension pulls the water molecules into the shape that has the smallest possible surface area, which is a sphere.
