surface tension is a strong version of which property of water

Surface tension is a strong version of cohesion , which is the attraction between water molecules.

Quick Scoop: Core Idea

  • Surface tension happens because water molecules at the surface are pulled strongly toward other water molecules below and beside them.
  • This inward pull is due to cohesion (water attracted to water), largely caused by hydrogen bonding between water molecules.
  • So, when a question asks “surface tension is a strong version of which property of water,” the answer is: the cohesive property of water.

Why Cohesion Matters Here

  • Cohesion makes water molecules stick together, and at the surface this sticking-together becomes especially strong, forming a kind of “skin” that is observed as surface tension.
  • This is why water can bead up on a penny, form nearly spherical droplets, or support a paperclip or water strider on its surface without breaking.

TL;DR: Surface tension is essentially a strong expression of water’s cohesion (attraction of water molecules to each other due to hydrogen bonding).
