How does the entropy change occur in the process of melting of a solid ?

Explanation

### Step-by-Step Solution:

1. **Definition of Entropy**:
- Entropy is a measure of the disorder or randomness in a system. The higher the entropy, the greater the disorder.

2. **State of Matter**:
- In the solid state, particles are closely packed together in a fixed structure, which results in low entropy due to minimal disorder.
