Attraction of water molecules to polar surfaces is known as

Options

A. Adhesion
B. Tensile strength
C. Surface tension
D. Cohesion

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the term that describes the attraction of water molecules to polar surfaces.

2. **Identifying Key Terms**: The key terms here are "water molecules," "polar surfaces," and "attraction."

3. **Exploring Options**: We need to evaluate the provided options to find the correct term:
- **Adhesion**: This is the property of water molecules binding to the molecules of many polar compounds. Since water is polar, it tends to adhere to other polar surfaces.
- **Tensile Strength**: This term refers to the resistance of a material to being pulled apart. It is not related to the attraction of water molecules.
- **Surface Tension**: This is a property of the surface of a liquid that allows it to resist external forces. While it is related to water, it does not specifically describe the attraction to polar surfaces.
- **Cohesion**: This refers to the attraction between similar molecules, such as water molecules attracting to each other, not to polar surfaces.

4. **Conclusion**: After evaluating all options, the correct answer is **Adhesion**, as it specifically refers to the attraction of water molecules to polar surfaces.

**Final Answer**: The attraction of water molecules to polar surfaces is known as **Adhesion**.
