What is the attraction between molecules of different substances called?

Explanation:
Adhesion is the attraction between molecules of different substances. This explains phenomena like water clinging to glass or plant cell walls, which enables capillary action where liquid rises against gravity. Cohesion, by contrast, is the attraction between like molecules (water to water), helping droplets form and stay together. Hydrogen bonds are a specific, strong type of intermolecular force that can contribute to adhesion in some cases, but adhesion refers to the broader idea of different substances sticking to each other. Ionic describes attractions between oppositely charged ions, not the general interaction between different substances.
