The melting point of naphthalene is `80^(@)C` and the room temperature is `30^(@)C`. A sample of liquid naphthalene at `100^(@)C` is cooled down to the room temperature. Draw a temperature time graph to represent this cooling. In the graph, mark the region which corresponds to the freezing process.

Explanation

To solve the problem, we need to create a temperature-time graph for the cooling of naphthalene from 100°C to room temperature (30°C). The melting point of naphthalene is 80°C, which is crucial for marking the freezing process on the graph.

### Step-by-Step Solution:

1. **Identify Initial and Final Temperatures**:
- Initial Temperature (T_initial) = 100°C (the temperature of the liquid naphthalene).
- Final Temperature (T_final) = 30°C (room temperature).
