Why liquids diffuse slowly as compared to gases?

Explanation

### Step-by-Step Solution:

1. **Understanding Diffusion**:
- Diffusion is the process by which molecules spread from an area of higher concentration to an area of lower concentration.

2. **Molecular Arrangement in Gases vs. Liquids**:
- In gases, the molecules are far apart from each other, which allows them to move freely and quickly.
- In liquids, the molecules are much closer together, which restricts their movement.
