Without seeing the specific graphic you are referring to, I can guide you on how to determine which property of water it might be illustrating.
-
Cohesion refers to the attraction between molecules of the same substance. It is responsible for water droplets forming and explains why water has a high surface tension.
-
Adhesion refers to the attraction between molecules of different substances. It explains how water can climb up the sides of a glass (capillary action).
-
Electronegativity relates to the ability of an atom to attract electrons. While it's a property of water's molecules due to the polar nature of water, it doesn’t manifest visually in the same way as cohesion and adhesion.
If the graphic shows water molecules sticking to each other or forming a droplet, that would demonstrate cohesion. If it shows water interacting with other surfaces or climbing up a tube, that would demonstrate adhesion. If it depicts both behaviors, then it illustrates both cohesion and adhesion.
Based on this analysis, you can determine which property is being demonstrated in the graphic you have.
