What is entropy change? What is the change of entropy with change of (i) temperature and (ii) pressure? Correlate the behaviour with the randomness.

Explanation

### Step-by-Step Solution

1. **Definition of Entropy Change**:
- Entropy change, denoted as ΔS, is a measure of the degree of randomness or disorder in a system. It quantifies how much the arrangement of particles in a system changes when a process occurs.

2. **Entropy and Temperature**:
- The change in entropy with respect to temperature can be expressed using the formula:
\[
