Question

the attraction between two different things, such as one water molecule sticking to a molecule of a different substances - for example, water sticking to a paper towel.

the attraction between two like things, such as one water molecule sticking to other water molecules - for example a drop of water sticking to another drop of water.

Explanation:

The first description (attraction between two different things, e.g., water and a paper towel) is the definition of adhesion. The second description (attraction between two like things, e.g., water molecules to each other) is the definition of cohesion. Assuming the question is to identify these terms (though the exact question isn't fully clear, but based on the definitions):

For the first box (water sticking to paper towel - different substances): This is adhesion.
For the second box (water molecules sticking to each other - like things): This is cohesion.

If the task was to match these definitions to terms (adhesion and cohesion), the first is adhesion, the second is cohesion.

Answer:

First description: Adhesion (attraction between different substances, e.g., water and paper towel).
Second description: Cohesion (attraction between like substances, e.g., water molecules to each other).
