Two test tubes X and Y are filled with water and mercury, respectively. After these two liquids were poured, water drops on the inner walls of X were observed but no mercury drops in Y were seen. Give reasons.

Explanation

To answer the question about why water drops were observed on the inner walls of test tube X (filled with water) but no mercury drops were seen in test tube Y (filled with mercury), we can break down the explanation into clear steps:

### Step-by-Step Solution:

1. **Understanding Adhesive and Cohesive Forces**:
- **Adhesive Forces**: These are the forces that attract different types of molecules to each other. For example, the attraction between water molecules and the glass of the test tube.
- **Cohesive Forces**: These are the forces that attract similar molecules to each other. For instance, the attraction between mercury molecules themselves.
