A potter shapes pots out of clay (Process 1). He then bakes the pots in an oven (Process 2). Which of the following statements is correct?

Options

A. Process 1 is a reversible, physical change while process 2 is an irreversible, physical change.
B. Process 1 is an irreversible, physical change while process 2 is an irreversible, chemical change.
C. Process 1 is a reversible, physical change while process 2 is an irreversible, chemical change.
D. None of these

Explanation

To determine the correct statement regarding the processes involved in shaping and baking pots, we can analyze each process step by step.

### Step-by-Step Solution:

1. **Identify Process 1**: The potter shapes pots out of clay.
- In this process, the potter takes clay and molds it into the desired shape.
- **Hint**: Think about whether the clay can return to its original form after being shaped.

2. **Determine the Nature of Process 1**:
- The shaping of clay is a **physical change**. This is because the composition of the clay remains the same, and it can be reshaped back into its original form if needed.
- **Hint**: Consider if the change can be reversed easily.

3. **Identify Process 2**: The potter bakes the pots in an oven.
- In this process, the shaped clay pots are subjected to heat in an oven.
- **Hint**: Think about what happens to the clay when it is exposed to high temperatures.

4. **Determine the Nature of Process 2**:
- Baking the pots causes a **chemical change**. The heat causes the clay to undergo a transformation, resulting in a hard, permanent structure that cannot revert back to its original clay form.
- **Hint**: Ask yourself if the change can be undone or if it results in a new substance.

5. **Conclusion**:
- Process 1 is a **reversible physical change** (shaping clay).
- Process 2 is an **irreversible chemical change** (baking the pots).
- Therefore, the correct statement is that Process 1 is reversible and a physical change, while Process 2 is irreversible and a chemical change.

### Final Answer:
- The correct statement is: Process 1 is a reversible physical change, and Process 2 is an irreversible chemical change.
