What is the attraction between molecules of different substances?

Explanation:
Adhesion is the attraction between molecules of different substances. It explains why a liquid spreads out and sticks to surfaces it touches, like water clinging to glass or plastic. This is different from cohesion, which is the attraction between like molecules (water to water) and is responsible for things like water droplets staying whole and surface tension at the surface. The term “water molecule” isn’t the attraction itself; it’s just an example of a molecule involved, not the interaction being described.
