What phenomenon is the result of water molecules' attraction to each other?

• A. Density
• B. Surface Tension
• C. High Specific Heat
• D. Capillarity

Answer: (B)

The phenomenon resulting from the attraction of water molecules to each other is known as surface tension. This occurs because water molecules are polar, leading to strong hydrogen bonds between them. At the surface of the water, molecules experience a net inward force due to the cohesive nature of these hydrogen bonds, which causes the surface of the water to behave like an elastic sheet. This is why small objects, insects like water striders, or even droplets can be held on the surface without sinking. Surface tension plays a crucial role in many biological and physical processes, such as how some organisms move on water, how liquids interact with solids, and how various phenomena related to liquids are observed in nature. This cohesive force is distinct from other phenomena related to water, such as density, high specific heat, and capillarity, all of which describe different properties and behaviors of water but are not directly linked to the molecular attraction at the surface.
