The boundary between liquids, like water, and gases, like air, is an ordered arrangement of hydrogen bonding of water molecules to each other at the surface and below the surface, but not with the molecules of gas in the air above the surface. This phenomenon is known as surface tension and is largely due to which property of water?
| cohesion |
| adhesion |
| heat of vaporization |
| evaporative cooling |
Homework Answers
The high surface tension of water is due to its cohesion forces of attaction between molecules. When the two molecules of water comes closer, the oxygen atom of one molecule is electrostatically attacted to hydrogen atom of other molecule. This electrostatic attraction is primarly due to the cohesion forces.
Hence, option A
