Question

Which example best represents the adhesion, cohesion, and surface tension of water?

Answer 1

The best example that represents the adhesion, cohesion, and surface tension of water is that water droplets forming a bead-like shape over a glass table. Cohesion: Water is pulled in to water. Adhesion: Water is pulled in to different substances. Adhesion and cohesion are water properties that influence each water particle on earth and furthermore the connection of water atoms with particles of different substances

Answer 2

To represent adhesion, consider droplets of water that fall onto a window as it is raining. These drops 'stick' onto the window until they evaporate or until are big enough to roll down the window. To represent cohesion, consider how water droplets rolling down a window quickly combine with other droplets to form a stream of water that flows down the window. To represent surface tension, consider a razor blade placed flat on it's side and it appears to 'float' on the water. However if placed in an upright position, it does not remain on top of the water.
