Question

what is adhesion? the attraction between two different kinds of molecules the attraction between 2 of the samekind of molecules same as cohesion the dissolving process

Explanation:

To determine the correct definition of adhesion, we analyze each option:

• The first option: Adhesion is defined as the attractive force between two different types of molecules. For example, water molecules adhering to the surface of a glass (where glass and water are different substances).
• The second option: The attraction between two of the same kind of molecules is cohesion (e.g., water molecules sticking to other water molecules).
• The third option: Adhesion and cohesion are distinct; cohesion is for like molecules, adhesion for unlike, so this is incorrect.
• The fourth option: Adhesion is not the dissolving process (dissolving involves a solute spreading in a solvent, different from molecular attraction between different substances).

Answer:

A. the attraction between two different kinds of molecules
