Which term refers to the attraction between different substances?

The term that refers to the attraction between different substances is adhesion. This phenomenon occurs when molecules of different substances interact due to attractive forces, such as hydrogen bonding or van der Waals forces. For example, when water molecules adhere to the surface of a glass, this adhesion is significant in various biological processes, including the movement of water in plants through capillary action.

In contrast, cohesion refers to the attraction between molecules of the same substance, such as water molecules attracting each other. A solution is a homogeneous mixture of two or more substances, and acids are substances that can donate protons (H+) in a chemical reaction. The concept of adhesion is crucial in understanding how different materials interact, particularly in biological contexts and processes.
