Question

3-4 sentences how cohesion and surface tension allows small insects to “walk on water

Answer 1

Cohesion refers to the attraction between molecules of the same substance, while surface tension is the result of this cohesive force at the surface of a liquid. In water, cohesive forces between water molecules create a surface tension strong enough to support small insects like water striders. These insects distribute their weight over a larger area, preventing them from breaking the surface tension, allowing them to "walk" across the water without sinking. This unique adaptation enables them to navigate aquatic environments efficiently while avoiding predators.
