State whether the following statements are true or false. In case a statement is false, write the corrected statement in your notebook
Cutting a log of wood into pieces is a chemical change. (True/False)

Explanation

**Step-by-Step Solution:**

1. **Understanding the Statement**: The statement given is "Cutting a log of wood into pieces is a chemical change." We need to determine if this statement is true or false.

2. **Identifying the Type of Change**: When we cut a log of wood, we are altering its size and shape but not its chemical composition. The wood remains wood, just in smaller pieces.

3. **Defining Physical vs. Chemical Change**:
- A **physical change** involves a change in physical properties (like size, shape, or state) without altering the chemical composition of the substance.
- A **chemical change** involves a change that results in the formation of new substances with different chemical properties.

4. **Analyzing the Cutting Process**: Cutting wood changes its physical form (from a large log to smaller pieces) but does not change what the wood is chemically. Therefore, this is a physical change.

5. **Conclusion**: Since the statement claims that cutting wood is a chemical change, and we have established that it is actually a physical change, the statement is false.

6. **Correcting the Statement**: The correct statement should be: "Cutting a log of wood into pieces is a physical change."
