Water sticks to glass due to______

Options

A. adhesive forces between water and glass.
B. cohesive forces between water and glass.
C. cohesive forces between water molecules.
D. cohesive forces between glass molecules.

Explanation

To answer the question "Water sticks to glass due to______," we can analyze the options provided and understand the concepts of adhesive and cohesive forces.

### Step-by-Step Solution:

1. **Understanding Adhesive Forces**:
- Adhesive forces are the attractive forces between unlike molecules. In this case, they refer to the attraction between water molecules and glass molecules.

2. **Understanding Cohesive Forces**:
- Cohesive forces are the attractive forces between like molecules. This means they refer to the attraction between water molecules themselves or glass molecules themselves.

3. **Analyzing the Options**:
- **Option 1**: Adhesive forces between water and glass - This option suggests that the sticking of water to glass is due to the attraction between the two different substances.
- **Option 2**: Cohesive forces between water and glass - This option is incorrect because it refers to the attraction between different substances, which is not cohesive.
- **Option 3**: Cohesive forces between water molecules - This option refers to the attraction between water molecules themselves, which does not explain why water sticks to glass.
- **Option 4**: Cohesive forces between glass molecules - This option is also incorrect as it refers to the attraction between glass molecules, which is not relevant to the sticking of water to glass.

4. **Conclusion**:
- The correct answer is **Option 1: Adhesive forces between water and glass**. This explains that water sticks to glass because of the attractive forces between the water molecules and the glass molecules.

### Final Answer:
Water sticks to glass due to **adhesive forces between water and glass**.
