State the third law of thermodynamics.

Explanation

### Step-by-Step Solution

1. **Understanding Entropy**:
- Entropy is defined as a measure of randomness or disorder in a closed system. Higher entropy indicates more disorder, while lower entropy indicates more order.

2. **Relation of Entropy with Temperature**:
- There is a direct relationship between entropy and temperature. As temperature increases, the entropy of the system also increases. Conversely, if the temperature decreases, the entropy decreases as well.
