State whether the following statements are true or false: Cutting of a log of wood is a reversible physical change.

Explanation

To determine whether the statement "Cutting of a log of wood is a reversible physical change" is true or false, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Physical Change**:
- A physical change is a change that does not result in the formation of a new substance. The original substance remains the same, even if its form or appearance changes.

2. **Analyze the Action of Cutting Wood**:
- When a log of wood is cut, it is divided into smaller pieces. However, the wood itself is still wood; no new substance is created.

3. **Determine Reversibility**:
- A reversible change is one that can be undone, meaning the original state can be restored. For instance, if you freeze water into ice, you can melt it back into water.

4. **Evaluate Cutting of Wood**:
- In the case of cutting a log, while you can physically join the pieces back together (e.g., using glue), you cannot restore the log to its original state as a single, intact log. Therefore, it is not reversible in the true sense.

5. **Conclusion**:
- Since cutting a log of wood is a physical change but not a reversible change, the statement "Cutting of a log of wood is a reversible physical change" is **false**.

### Final Answer:
The statement is **false**.
