Adhesion is best described as which of the following?

• A. A property of water that helps moderate Earth's temperature
• B. The process by which a crystalline lattice forms
• C. The process that contributes to the transport of water and dissolved nutrients in plants by causing water molecules to tug on other water molecules
• D. The clinging of one substance to another substance

Answer: (D)

Verified step by step guidance

1. Understand the concept of adhesion: Adhesion refers to the attraction between molecules of different substances. This is different from cohesion, which is the attraction between molecules of the same substance.
2. Consider the role of adhesion in biological systems: In plants, adhesion helps water molecules stick to the walls of plant vessels, aiding in the transport of water and nutrients.
3. Differentiate between adhesion and other properties of water: While adhesion involves different substances, cohesion involves the same substance, and both are crucial for processes like capillary action in plants.
4. Evaluate the given options: The first option describes a property of water related to temperature regulation, which is not adhesion. The second option describes crystallization, which is unrelated to adhesion.
5. Identify the correct description: The correct description of adhesion is 'The clinging of one substance to another substance,' as it accurately defines the process of adhesion.
