Why does the entropy of a solid increase on melting?

Explanation

**Step-by-Step Solution:**

1. **Understanding Entropy**: Entropy is a measure of the degree of randomness or disorder in a system. Higher entropy indicates a greater degree of disorder.

2. **Solid State Characteristics**: In a solid state, molecules are closely packed together in a fixed arrangement. The intermolecular forces are strong, which restricts the movement of the molecules. This results in a low degree of randomness.

3. **Melting Process**: When a solid melts, it transforms into a liquid. During this process, the strong intermolecular forces that hold the molecules in a fixed position are overcome by thermal energy.
