Compare the density of water at `4^(@)C` with that below and above `4^(@)C`.

Explanation

To compare the density of water at 4°C with that below and above 4°C, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Density**:
- Density is defined as mass per unit volume (Density = Mass/Volume).
- For a given mass, if the volume increases, the density decreases, and vice versa.
